Study of Macro level Properties of SCC using GGBS and Lime stone powderIJERD Editor
One of the major environmental concerns is the disposal of the waste materials and utilization of
industrial by products. Lime stone quarries will produce millions of tons waste dust powder every year. Having
considerable high degree of fineness in comparision to cement this material may be utilized as a partial
replacement to cement. For this purpose an experiment is conducted to investigate the possibility of using lime
stone powder in the production of SCC with combined use GGBS and how it affects the fresh and mechanical
properties of SCC. First SCC is made by replacing cement with GGBS in percentages like 10, 20, 30, 40, 50 and
by taking the optimum mix with GGBS lime stone powder is blended to mix in percentages like 5, 10, 15, 20 as

Experimental Investigation on the Concrete as a Partial Replacement of Fine a...IJSRD
This project work involves in an experimental study on the concrete by using stone dust and brick dust on the mechanical properties of the concrete. In this experimental study two types admixtures are used in preparation of concrete mix. Stone dust and brick dust are added from 0% to 25% by weight of fine aggregate with increment of 5%. A comparative analysis has been carried out for conventional concrete to that of the admixture concrete in relation to their compressive, split tensile and flexural strength properties. As the stone dust and brick dust content increases in cement concrete, the compressive and split tensile values are proportionally increasing. It is observed that at 20% of stone dust and brick dust is the optimum dosages for concrete mixture.
Durability of Bricks Cast With Industrial SludgeIOSR Journals
Abstract: Recovery of waste constituents from industrial waste is a cost effective solution in control of
environmental pollution. Present investigation deals with the feasibility of usage of sludge obtained from sand
beneficiation treatment plant in the production of bricks and their durability. The experimental results show that
the brick earth can be replaced with treatment plant sludge up to 40% by weight without loss in strength and
other brick characteristics considered satisfactory for conventional purposes. Apart from that when reference
specimens and test bricks (5% Sludge) were immersed in various concentrations of hydrochloric acid (HCl)
solution at different immersed ages, the loss of weight is found to be less in test bricks than that in reference
bricks. Hence, at 5% of replacement, the quality of bricks is superior to the bricks made from earth alone and
can be used for superior work of permanent nature.

Durability Studies on Concrete with Hypo Sludge as Partial Replacement of CementIJERA Editor
This paper summarizes the research work on the properties of hypo sludge when used as partial replacement for
Ordinary Portland Cement (OPC) in concrete. OPC was replaced with hypo sludge by weight at 0%, 5%, 10%,
15%, 20% and 25%. 0% replacement served as the control. Compacting factor test was carried out on fresh
concrete while Compressive Strength test was carried out on hardened 150mm concrete cubes after 7, 14 and 28
days curing in water. The results revealed that the Compacting factor decreased as the percentage replacement
of OPC with hypo sludge increased. The compressive strength of the hardened concrete also decreased with
increasing OPC replacement with hypo sludge. It is recommended that further studies be carried out to gather
more facts about the suitability of partial replacement of OPC with hypo sludge in concrete.
Use of Over-Burnt Bricks as Coarse aggregate in ConcreteEditorIJAERD
In modern construction industry number of materials are used and one of the materials is Brick. Regular
bricks are generally used in buildings or in some other engineering applications. In manufacturing of these bricks, a lot
of waste is produced in the form of over- burnt-bricks. The bricks being near to the fire in the furnace receives a
temperature more heat and eventually shrink and loose its shape, its color becomes reddish. These bricks can’t be used
in construction, directly because of their distorted shape dark color. hose over-burnt brick could be a source of recycled
coarse aggregate. The primary goal of this paper is to assess the suitability of incorporating over-burnt bricks in
concrete, by the partial replacement of natural coarse aggregate (NCA) with overburnt brick aggregate (OBBA) in a
ratio of 20%, 50%, and 100%. Initially, mix proportion of 1:2:4 and w/c of 0.57 was selected. By replacing NCA with
OBBA while using mix proportion of 1:2:4 and w/c of 0.57, the resulting concrete was found non-mixable and nonworkable. Thus, mix was designed (for targeted strength of 4ksi) for all replacement percentages. Slump test was
conducted for each replacement and the results show that by increasing replacement percentage the workability of
concrete decreases. the slump values are in between the range of 3–1.5 inches. For compressive strength the cylindrical
specimens of 6" x 12" were tested at 3, 7, and 28 days. For 20% replacement, the loss in compressive strength is 42.16%
for 3 days and for 7 and 28 days the loss is 46.96% and 61.37% respectively. For 50 % replacement, the loss in strength
for 3, 7 and 28 days is 29.73%, 30.87% and 58.29% respectively. For 100% replacement, the loss in strength for 3, 7 and
28 days is 48.65%, 55.65% and 69.19%.
Experimental Study on Concrete with Waste Granite Powder as an AdmixtureIJERA Editor
Granite fines which are the byproduct produced in granite factories while cutting huge granite rocks to the desired shapes. Granite fines are used as a filler material in the concrete, replacing the fine aggregate which will help in filling up the pores in the concrete. Filling up of the pores by granite fines increase the strength of the concrete and also a material which is abundantly to investigate the strength behavior of concrete with use of granite fines as an additive. Concrete is prepared with granite fines as a replacement of fine concrete in 4 different propositions namely 2.5%, 5%, 7.5% and 10% and various tests such as compressive strength, split tensile strength and flexural strength are investigated and these values are compared with the conventional concrete without the granite fines. It was observed that substitution of 7.5% of cement by weight with Granite fines in concrete resulted in an increase in compressive strength for both 7 & 28 days to 33.14 & 43.40 N/mm2 compared to 23.26 & 39.41 N/mm2 of conventional concrete. Tensile strength too followed a similar pattern with a 7.5% substitution with granite fines increasing the tensile strength for 7 & 28 days to 2.87 &4.19 N/mm2 compared with a 2.4 & 3.4 N/mm2 of conventional concrete. However flexure strength of 7.5% granite fine replacement exhibited a good improvement of flexural strength for 28 days to 6.34 N/mm2compared to a 3.35 N/mm2 of conventional concrete. Further investigations revealed that to attain the same strength of conventional concrete a 10% substitution with granite fines is effective. So it can be concluded that when locally available granite is a good partial substitute to concrete and improves compressive, tensile and flexure characteristics of concrete, while simultaneously offsetting the overall cost of concrete substantially.

The use of Recycled Concrete Aggregate (RCA) is gaining importance throughout the globe due to
the depleting sources of natural aggregate and disposal problem of demolished waste. The advancement in the
prestressed concrete technology and multistoried structures has given impetus for making concrete of high
strength. Also, it is well established that the fibers make concrete ductile. The aim of this research work is to
determine the suitability of glass fibers for use in structural recycled aggregate concrete of high strength. The
fresh and hardened state properties of partially replaced recycled aggregate concrete, with varying percentages
of glass fibers, are compared with the corresponding conventional aggregate concrete. The compressive, split
tensile and flexural strengths of M50 grade concrete with various replacement levels of coarse aggregate were
done . The maximum values of all these strengths were obtained at 1.5% of fiber content
Partial Replacement of Cement by Saw Dust Ash in Concrete A Sustainable ApproachIJERD Editor
Concrete industry is one of the largest consumers of natural resources due to which sustainability of concrete industry is under threat. The environmental and economic concern is the biggest challenge concrete industry is facing. In this paper, the issues of environmental and economic concern are addressed by the use of saw dust ash as partial replacement of cement in concrete. Cement was replaced by Saw Dust Ash as 5%, 10%, 15% and 20% by weight for M-25 mix. The concrete specimens were tested for compressive strength, durability (water absorption) and density at 28 days of age and the results obtained were compared with those of normal concrete. The results concluded the permissibility of using Saw Dust Ash as partial replacement of cement up to 10% by weight for particle size of range 90micron.

Huge quantity of Cotton stalk ash and rice husk ash are generating as a waste product in agriculture sector in India and many other developing countries every year. In lack of proper wakefulness and technology expansion, great portion of these by products remain unutilized causing severe disposal and environmental troubles. The main goal of this thesis is to examine the performance of M40 grade concrete with a mix ratio as per M40 grade and a water cement ratio of 0.425 Additionally, it aims to determine the compressive strength, flexural strength, and split tensile strength of concrete cement when cotton stalk ash and rice husk ash are used in place of cement. With various percentage like 10, 20, and 30 etc. of cotton stalk ash and rice husk ash well as with combined replacement of Cotton stalk ash and rice husk ash. and results that the workability of concrete was found to be reduced on enhance the Cotton stalk ash CSA , rice husk ash RHA by difference percentages. The Maximum increase in 53.67 N mm2 of compressive strength is obtained after the period 28 days with cotton stalk ash substituting 10 of the cement CSA . The maximum increase in flexural strength over the period of 28 days was 5.98 N mm2, with cotton stalk ash substituting 10 of the cement CSA . When 10 of the cement is replaced with cotton stalk ash, the significant increase in split tensile strength for 28 days is 4.23N mm2 CSA By substituting cotton stalk ash, rice husk ash for 20, 10 of the cement, the compressive strength as per this investigations for 28 days is observed 49.47 N mm2 CSA, RHA is not achieved highest value but achieve the target mean strength. The greatest results are achieved when cotton stalk ash are utilized, although at different percentages.

Cement is the main construction material for making concrete. It provides good bonding between aggregates and also provides strength. But at the time of manufacturing, cement releases high amount of CO2. In order to reduce the environmental impact and to improve the property of concrete, Palm ash concrete are used. Palm ash concrete containing palm ash as partial substitute for cement. The replacement percentages are 10%, 20%, 30%. In these investigations, compressive strength and durability of palm ash concrete and normal concrete were found out. Results are tabulated and discussed. The properties of palm ash concrete are also compared with the conventional concrete. The palm ash concrete is very economical and also ecofriendly concrete
Waste concrete is one of the most usable and economic kind of concrete which is used in many civil projects all around the world, and its importance is undeniable. Also, the explanation of constructional process and destruction of them cause the extensive growth of irreversible waste to the industry cycle, which can be as one of the main damaging factors to the economy. In this investigation, with using of constructional waste included concrete waste, brick, ceramic and tile and stone new aggregate was made. Also it was used with different weight ratios of cement in the mix design. The results of laboratory studies showed that the using of the ratio of sand to cement 1 and waste aggregate with 20% weight ratio (W20), replacing of normal aggregate, increased the 28 days compressive strength to the maximum stage 45.23 MPa. In the next stage, in order to develop the experimental results backpropagation neural network was used. This network with about 91% regression, 0.24 error, and 1.41 seconds, is a proper method for estimating results.
The results of an experimental investigation to study the effects of partial replacement of cement with fly ash in rubberized and coconut shell concrete. The percentage of rubber used in this study was 5% replaced with coarse aggregate and fly ash varies from 0-20% were replaced with cement in conventional concrete. One size of tire rubber chips are used of about 10mm.
Rubber is produced excessively worldwide every year. It cannot be discharge off easily in the environment as its decomposition takes much time and also produces environmental pollution. In such a case the reuse of rubber would be a better choice.
In order to reuse rubber wastes, it was added to concrete as coarse aggregate and its different properties like compressive strength, Tensile strength, ductility etc. were investigated and compared with ordinary concrete.
As a result it was found that rubberized concrete is durable, less ductile, has greater crack resistance but has a low compressive strength when compared with ordinary concrete. The compressive strength of rubberized concrete can be increased by adding some amount of silica to it.
Properties of concrete with coconut shells (CS) as aggregate replacement were studied. Control concrete with normal aggregate and CS concrete with 10-20% coarse aggregate replacement with CS were made. Two mixes with CS and fly ash were also made to investigate fly ash effect on CS replaced concretes. Constant water to cementitious ratio of 0.6 was maintained for all the concretes. Properties like compressive strength, split tensile strength, water absorption and moisture migration were investigated in the laboratory. The results showed that, density of the concretes decreases with increase in CS percent.
Workability decreased with increase in CS replacement. Compressive and split tensile strengths of CS concretes were lower than control concrete. Permeable voids, absorption and sorption were higher for CS replaced concretes than control concrete. Coarse aggregate replacement with equivalent weight of fly ash had no influence when compared with properties of corresponding CS replaced concrete
The mix design was targeted to be M15 grade of concrete. The mix proportion of concrete was 1:2:4 with water cement ratio of 0.45.The fresh and hardened properties of rubberized concrete produced at two different replacements ratios of fly ash compared to the conventional concrete without rubber and fly ash.
The test result indicate that there was a small reduction in the strength with the 5% replacement in rubber content as compared with the conventional concrete. However, the increase of fly ash from 10% to 20% improved the mechanical properties of rubberized and coconut shell concrete.
This study explores the effects of rubber particles and coconut shell on some properties of concrete.

After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

ABSTRACT
Conservation of natural resources and preservation of environment is the essence of any development. The
problem arising from continuous technological and industrial development is the disposal of waste material. If
some of the waste materials are found suitable in concrete making, not only cost of construction can be cut
down, but also safe disposal of waste materials can be achieved. So in our project, an attempt has been made to
assess the suitability of stone with waste tills in concrete making. In the laboratory tiles has been tried as coarse
aggregate has been used as partial substitute to conventional coarse aggregate concrete making and today many
researches are ongoing into the use of Portland cement replacements, using many waste materials like
pulverized fly ash (PFA) and ground granulated blast furnace slag (GGBS). Like PFA and GGBS a waste glass
powder (GLP) is also used as a binder with partial replacement of cement which takes some part of reaction at
the time of hydration. In this study, rice husk ash have been used as partially replacements to the cement Cubes
were cast and tested for compressive strength, and modulus of rupture after a curing period of 7,17,28 days. The
results indicated effectiveness of tiles as coarse aggregate by partial replacement of conventional concrete by 20
%, 30%, 50%and cement as rice husk ash with 10%,15% and 20% without affecting the design strength. Also
Combined RHA & Tiles replacement is in above percentage mixing. A total number of 81 cubes, and were cast
and tested .This paper recommends that waste ceramic tiles can be used as an alternate construction material to
coarse aggregate in concrete. Also recommended to cement is partially rice husk ash.

I. INTRODUCTION
Concrete is the world’s most consumed
material. Production of concrete relies to a large
extent on the availability of cement, sand and coarse
aggregates such as granite, the costs of which have
risen astronomically over the past few years. The
negative consequences of the increasing demand for
concrete include depletion of aggregate deposits;
environmental degradation and ecological imbalance.
Rising construction costs and the need to reduce
environmental stresses to make construction
sustainable, has necessitated research into the use of
alternative materials, especially locally available ones
which can replace conventional ones used in concrete
production. If some of the waste material are found
suitable in concrete making with use of waste tiles.
This study not only reducing cost of construction.
Also safe disposals of waste material can be
achieved. The use of cheaper material without loss of
performance is very crucial to the growth of
development of countries. this study also
experimental investigation done to study the effect
of partial replacement of cement on Rice Husk Ash
by 10%, 15% 20% and waste tiles by 20% 30% 50%
Numerous tests are performed on wet concrete such
as workability test, such as compaction factor test,
and slump cone test. The tests on hardened concrete
are destructive test while compressive test. The tests
on hardened concrete are destructive test while the
destructive test includes compressive test on concrete
cube for size (150 x 150 x 150) mm. In actual
practice, test on workability of wet concrete are
carried out to ensure uniform quality concrete only.
Strength is not a measurable at that stage with the
available technology. RHA has two roles in concrete
manufacture, as a substitute for cement, reducing the
cost and weight of concrete in the production of low
cost building blocks. The workability of RHA
concrete has been found to decrease but OPC
increases the workability of concrete so RHA and
OPC mix together in concrete to improve the
workability of concrete. The work presented in this
paper reports an investigation on the behavior of
concrete produced from blending cement with OPC

III. EXPERIMENTAL PROGRAM
The mix design is produced for maximum
size of aggregate is 20mm conventional aggregate
and crushed ceramic aggregate. The variation of
strength of hardened concrete using solid wastes as
partial replacement of conventional aggregate is
studied by casting cubes, until 50%. The concrete
was prepared in the laboratory using mixer. The
cement, fine aggregate and coarse aggregate and
solid wastes tiles and rice husk ash are mixed in dry
state and then the desired water quantity is added and
the whole concrete is mixed for 5 minutes, the
concrete is poured in the mould which is screwed
tightly. The concrete is poured into the mould in 3
layers by poking with tamping rod for cubes of

IV. RESULTS AND DISCUSSION
4.1 GENERAL
In order to assess mechanical properties of
concrete using waste tiles aggregates and cement by
RHA with partial replacement, suitable size
specimens were cast and tested at the appropriate
ages as per the guidelines of I.S 516-1959. Care was
taken to maintain accuracy of weight of the concrete
ingredients and well calibrated measuring devices
used to find the loads. This chapter presents the test
results and discussion.
4.2 COMPRESSIVE STRENGTH
Compressive strength has been found out at
the ages 7, 14 and 28 days after moist curing the
specimens continuously. The test results are
presented in table 6.1.
Strength of concrete mainly depends on
three factors viz.
i. Strength of coarse aggregate ;
Ii Strength of mortar matrix;
Iii Bond strength between mortar part and
coarse aggregate;
The result of the present investigation reveals
that the strength of concrete up to 25MPa is governed
by the strength of all the above factors.
Strength of concrete beyond the level is
governed by the strength of the aggregate alone.

V. CONCLUSIONS
Following are the conclusions can be made
based up on the studies made by various researchers:-
Waste tiles can be used to replace some of the
aggregates in a concrete mixture. This
contributes to reducing the unit weight of the
concrete. This is useful in applications requiring
nonbearing light weight concrete, such as
concrete panels used in facades, foot bath.
For a given w/c, the use of tiles in the mix
lowers the density, compressive strength and of
concrete.
The effect of water-cement ratio of strength
development is not prominent in the case of
RHA concrete. It is because of the fact that the
TILES aggregates reduce the bond strength of
concrete. Therefore, the failure of concrete
occurs due to failure of bond between the cement
paste and TILES aggregates.
Introduction of Tiles in concrete tends to make
concrete ductile, hence increasing the ability of
concrete to significantly deform before failure.
This characteristic makes the concrete useful in
situations where it will be subjected to harsh
weather such as expansion and contraction, or
freeze and thaw.
The inclusion of tiles aggregates in the concrete
of the buildings under investigation has been
