In persuit of alternative ingredients to cement concrete constructioneSAT Journals
Abstract Due to rapid demand and growth in infrastructure, the natural resources are fast depleting. The production of cement and aggregates consume energy which are responsible for increase in concentration of carbon dioxide in atmosphere. On the other hand huge amount of wastes are generated in various fields which are not being utilized other than for landfilling, incineration and a very few reused having a recycle value. Some wastes are biodegradable while others are toxic or harmful to environment. Hence there appears to be an urgent need to search for alternative materials, which can replace existing ingredients partially or fully, thereby reducing energy consumption and reduced CO2 emission. This paper discusses some options which appear to be promising in this direction. Index Terms: Eco-Friendly Concrete, Sustainability, Substitutes for Binders, Substitutes for Aggregates

structural and modal analysis of an engine block by varying materialsIjripublishers Ijri
The largest part of the engine is cylinder block. The upper section of the cylinder block consists of cylinders and pistons. Crankcase is supported by the crankshaft and it is placed in the lower section. Aluminum cylinder blocks are lighter than the cast-iron cylinder blocks of the same size. Cylinder block, pistons, cylinder head, crankshaft and connecting rods are the major elements of the engine. IC engine cooling uses either a liquid or gas to remove the unnecessary heat from an internal combustion engine. For special purpose and small engines, air cooling makes for a lightweight and relatively simple system, if we use the materials with better waste heat dissipation it will help in achieving better efficiencies and long life of the engine.

he present paper deals with the effect of volume fraction of fillers on the thermal Properties of polymer composites. This work sees an opportunity of enhancement on insulation capability of a typical fiber reinforced polymer composite. To validate this mathematical model, a set of epoxy based composites, with fiber content ranging 4.38 to 20.10% of volume fractions have been prepared by simple hand lay-up technique. For preparing the composite, natural fiber i.e. Pine apple leaf fibers are incorporated in Epoxy Resin. Thermal conductivities of these composite samples are measured as per ASTM standard E-1530 by using the Unitherm™ Model 2022 tester, which operates on the double guarded heat flow principle at the temperature ranging from 30˚C to 150˚C. And also the Specific Heat of the powdered samples are measured by using Differential Scanning Calorimeter (DSC). By using the MATLAB the numerical analysis is carried out to find the value of Thermal Diffusivity with varying temperatures. It was observed that the thermal diffusivity varies with fiber concentration, but the variation of thermal diffusivity with varying temperature was not so significant.

With the growing quantity of pictures users distribute from node to node social networks, retaining confidentiality has turn out to be a foremost predicament, as declared by a latest wave of made known occurrences wherever users unintentionally shared individual profile. In radiance of these occurrences made necessitate of tools to assist users organize access to their distributed data is evident. In the direction of speak to this requirement, we suggest an Adaptive Privacy Policy forecast (A3P) scheme to facilitate users compile confidentiality settings for their pictures. We observe the responsibility of communal context, picture content, and metadata as possible sign of users’ confidentiality preference. We recommend a two-level structure which according to the user’s obtainable times past on the site, establishs the most excellent obtainable confidentiality policy for the user’s pictures being uploaded. Our solution relies on an image classification framework for image categories which may be associated with similar policies, and on a policy prediction algorithm to automatically generate a policy for each newly uploaded image, also according to users’ social features. Over time, the generated policies will follow the evolution of users’ privacy attitude. We provide the results of our extensive evaluation over 5,000 policies, which demonstrate the effectiveness of our system, with prediction accuracies over 90 percent.

In available practically proven Data clustering practices for eradicating same copies of replicated data, Data de-replication is one of significant mechanisms, and has been extensively practiced in cloud storage to diminish the quantity of storage space and accumulate bandwidth. To guard the privacy of responsive data though sustaining de-replication, the convergent encryption technique has been anticipated to encrypt the data before redirecting. For an improvised shielding of data safety, this paper formulates the primary effort to formally speak to the problem of approved data de-replication. Diverse from conventional de-replication systems, the discrepancy privileges of users are auxiliary considered in replica verification besides the data itself. In this we introduce several novel de-replication structural methods in sustaining approved replica test in hybrid cloud architecture. Safety examination demonstrates that our system is protected in terms of the description particular in the anticipated security model. As an evidence of perception, we execute a model of our anticipated approved replica check method and perform test-bed research using our model. We demonstrate that our anticipated approved replica check method acquire minimal overhead evaluated to standard procedures.

Ijri ece-01-02 image enhancement aided denoising using dual tree complex wave...Ijripublishers Ijri
This paper presents a novel way to reduce noise introduced or exacerbated by image enhancement methods, in particular algorithms based on the random spray sampling technique, but not only. According to the nature of sprays, output images of spray-based methods tend to exhibit noise with unknown statistical distribution. To avoid inappropriate assumptions on the statistical characteristics of noise, a different one is made. In fact, the non-enhanced image is considered to be either free of noise or affected by non-perceivable levels of noise. Taking advantage of the higher sensitivity of the human visual system to changes in brightness, the analysis can be limited to the luma channel of both the non-enhanced and enhanced image. Also, given the importance of directional content in human vision, the analysis is performed through the dual-tree complex wavelet transform , lanczos interpolator and edge preserving smoothing filters. Unlike the discrete wavelet transform, the DTWCT allows for distinction of data directionality in the transform space. For each level of the transform, the standard deviation of the non-enhanced image coefficients is computed across the six orientations of the DTWCT, then it is normalized.
Keywords: dual-tree complex wavelet transform (DTWCT), lanczos interpolator, edge preserving smoothing filters.

Conventional refrigeration system is a type of refrigeration systems which are costly; noisy, harmful gases released from a machine based on application of this type of system and it is required more maintenance. So, we need to go for unconventional refrigeration systems like vortex tube refrigeration system, which produce less vibrations and which require less maintenance and which are noiseless. It is required for our mechanical engineers to look for enhancing the performance of such vortex tubes. So as a part of my project work, I have chosen various sizes of vortex tubes and test their performances for finding out optimum performance.

Ijri te-03-013 modeling and thermal analysis of air-conditioner evaporatorIjripublishers Ijri
Air conditioning evaporator works by absorb heat from the area (medium) that need to be cooled. It does that by maintaining the evaporator coil at low temperature and pressure than the surrounding air. Since, the AC evaporator coil contains refrigerant that absorbs heat from the surrounding air, the refrigerant temperature must be lower than the air.
In our project we have modeling an air-cooled evaporator for a home 1.5ton air conditioner. Presently the material used for coils is copper and the material used for fins is copper or aluminum. A 3D model of the evaporator is done in parametric software Pro/Engineer.
To validate the temperatures and other thermal quantities like flux and gradient, thermal analysis is done on the evaporator coil by applying properties copper and suitable material like aluminum. And also we are varying inside cooling fluid Hydrocarbon (HC) and Hydro chloroflouro carbon (HCFC).The best material for the evaporator of our design can be checked by comparing the results.
Thermal analysis is done in ANSYS.

Water-cooled chiller systems have typically been designed around entering condenser water temperatures of 85°F with a Optimization of Water - Cooled Chiller – Cooling Tower Combinations The warm water leaving the chilled water coils is pumped to the evaporator of the chiller, where the unwanted heat from the building is transferred by the latent heat of vaporization of the refrigerant. The compressor of the chiller then compresses the refrigerant to a higher pressure, adding the heat of compression in the process. The high pressure refrigerant then moves to the economical condenser water flow of 3.0 USGPM/ton and a 10°F denser, where the unwanted heat is rerange. In recent years, there has been considerable debate on the merits of designing around lower condenser water flow rates with a higher range in order to improve system lifecycle costs. However, two other parameters must also be considered in any analysis - approach and design wet bulb. The question to be answered is: What nominal condenser water flow rate and approach is best from a first cost standpoint as well as from a full load energy standpoint at any given wet bulb.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

INTRODUCTION
Global warming and Environmental pollution is now a
global concern. Cellular Light Weight Technology blocks
can be used as an alternative to the red bricks, to reduce
Environmental pollution and Global warming.
It is produced by initially making slurry of Cement + Fly
Ash + Water, which is further mixed with the addition
of pre-formed stable foam in an ordinary concrete mixer
under ambient conditions. The addition of foam to the
concrete mixture creates millions of tiny voids or cells in
the material, hence the name Cellular Concrete.
Bricks remain one of the most important building materi-
als in the country. Brick making is a traditional industry
in India, generally confined to rural areas. In recent years,
with expanding urbanization and increasing demand for
construction materials, brick kilns have to grow to meet
the demand. It has directly or indirectly caused a series
of environmental and health problems. At a local level (in
the vicinity of a brick kiln), environmental pollution from
brick-making operations is injurious to human health,
animals and plant life. At a global level, environmental
pollution from brick-making operations contributes to the
phenomena of global warming and climate change. Also,
extreme weather may cause degradation of the brick sur-
face due to frost damage.
CLC blocks are environment friendly. The energy con-
sumed in the production of CLC blocks is only a fraction
compared to the production of red bricks and emits no
pollutants and creates no toxic products or by products.
It is produced by initially making a slurry of Cement +
Fly Ash + Water, which is further mixed with the addi-
tion of pre-formed stable foam in an ordinary concrete
mixer under ambient conditions. Based on the trial mix-
es, it is found that compressive strength of CLC blocks is
more than the compressive strength of conventional clay
bricks. The addition of foam to the concrete mixture cre-
ates millions of tiny voids or cells in the material, hence
the name Cellular Concrete.
MATERIALS AND ITS PROPERTIES
CEMENT AND ITS PROPERTIES:
Portland cement is the most common type of cement in
general use around the world, used as a basic ingredi-
ent of concrete, mortar, stucco, and most non-specialty
grout. It was developed from other types of hydraulic lime
in England in the mid-19th century and usually origi-
nates from limestone. It is a fine powder produced by
heating materials in a kiln to form what is called clinker,
grinding the clinker, and adding small amounts of other
Abstract
Burnt Clay Brick is the predominant construction material in the country. The CO2
emissions in the brick manufacture
process have been acknowledged as a significant factor to global warming. Now-a-days there are so many technologies
involved in the recent development of concrete. Cellular Lightweight Concrete (CLC) is one of the recent emerging tech-
nology in making concrete. The usage of Cellular Light-weight Concrete (CLC) gives a prospective solution to building
construction industry along with environmental preservation. By using this type of concrete, we have found so many
advantages when compared to the burnt clay bricks.
Cellular Light Weight Technology blocks can be used as an alternative to the red bricks, to reduce Environmental pol-
lution and Global warming. It is produced by initially making slurry of Cement, Fly Ash and Water with different mix
designs, which is further mixed with the addition of pre-formed stable foam in an ordinary concrete mixer under ambi-
ent conditions. The addition of foam to the concrete mixture creates millions of tiny voids or cells in the material, hence
the name Cellular Concrete.
The density is considerably reduced by using fly ash based cellular lightweight concrete than normal concrete and at
the same time, the strength is not affected by appropriate design mix. When we use this type of concrete we achieve
large volume by less amount of concrete. The manufacturing process of this type of concrete does not involve any high
cost techniques. Manufacturing process of CLC is similar to normal concrete and in this additionally foam generating
machine is used.

materials. Several types of Portland cement are available
with the most common being called ordinary Portland ce-
ment (OPC) which is grey in color, but a white Portland
cement is also available.
It is a fine mineral powder manufactured with very pre-
cise processes. Mixed with water, this powder transforms
into a paste that binds and hardens when submerged in
water. Because the composition and fineness of the pow-
der may vary, cement has different properties depending
upon its makeup.
Cement is made by grinding together a mixture of lime-
stone and clay, which is then heated at a temperature
of 1,450°C. What results is a granular substance called
"clinker," a combination of calcium, silicate, alumina and
iron oxide.
Cement complying with any of the fol1owing Indian
Standards may be used at the discretion of the manu-
facturer:
• 43 Grade ordinary Portland cement,
• 53 Grade ordinary Portland cement
• Rapid hardening Portland cement
• Sulphate resisting Portland cement
• Portland pozzolana cement and
• Portland slag cement.
Cement
PROPERTIES:
1. It possesses a high compressive strength.
2. It is a corrosion resistance material and atmospheric
agent has no appreciable effect on it.
3. It hardens with age the process of hardening continues
for a long time after the concrete has attained sufficient
strength. It is this property of cement concrete which
gives it a distinct place among building materials.
4. It is more economical than steel.
5. It binds rapidly with steel and as it is weak in ten-
sion, the steel reinforcement is placed in cement concrete
at suitable places to take up the tensile stresses. This is
termed as the reinforced cement concrete or simply as
R.C.C.
6. Under the following two conditions, it has a tendency
to shrink:
a. There is initial shrinkage of cement concrete which is
mainly due to the loss of water through forms, absorption
by surfaces of forms etc.
b. The shrinkage of cement concrete occurs as it hard-
ens. This tendency of cement concrete can be minimized
by proper curing of concrete.
7. It has a tendency to be porous. This is due to the pres-
ence of voids which are formed during and after its plac-
ing. The two precautions necessary to avoid this tendency
are as follows:
a. There should be proper grading and consolidating of
the aggregates.
b. The minimum water-cement ratio should be adopted.
8. It forms a hard surface, capable of resisting abrasion.
9. It should be remembered that apart from other materi-
als, the concrete comes to the site in the form of raw ma-
terials only. Its final strength and quality depend entirely
on local conditions and persons handling it.
FLY ASH AND ITS PROPERTIES:
Fly ash, also known as "pulverized fuel ash" in the United
Kingdom, is one of the residues generated by coal com-
bustion, and is composed of the fine particles that are
driven out of the boiler with the flue gases. Ash that falls
in the bottom of the boiler is called bottom ash. Fly ash is
generally captured by electrostatic precipitators or other
particle filtration equipment before the flue gases reach
the chimneys of coal-fired power plants, and together
with bottom ash removed from the bottom of the boiler
is known as coal ash. Depending upon the source and
makeup of the coal being burned, the components of fly
ash vary considerably, but all fly ash includes substantial
amounts of silicon dioxide (SiO2) (both amorphous and
crystalline), aluminum oxide (Al2O3) and calcium oxide
(CaO), the main mineral compounds in coal-bearing rock
strata.
Constituents depend upon the specific coal bed makeup,
but may include one or more of the following elements
or substances found in trace concentrations (up to hun-
dreds ppm):arsenic, beryllium, boron, cadmium, chro-
mium, hexavalent chromium, cobalt, lead,manganese,
mercury, molybdenum, selenium, strontium, thallium,
and vanadium, along with very small concentrations of
dioxins and PAH compounds.
In the past, fly ash was generally released into the atmos-
phere, but air pollution control standards now require
that it be captured prior to release by fitting pollution
control equipment. In the US, fly ash is generally stored
at coal power plants or placed in landfills. About 43% is
recycled often used as a pozzolan to produce hydraulic
cement or hydraulic plaster or a partial replacement for
Portland cement in concrete production. Pozzolan ensure
the setting of concrete and plaster and provide concrete
with more protection from wet conditions and chemical
attack.

EXPERIMENTAL INVESTIGATION
Process of casting clc blocks mix
The concrete mix design indicating the proportions of
various ingredients should be worked out carefully keep-
ing in view the desired physical properties of the finished
blocks.
Requirements of concrete mix design
The requirements which form the basis of selection and
proportioning of mix ingredients are:
• The minimum compressive strength required from
structural consideration.
• The adequate workability necessary for full compaction
with the compacting equipment available.
• Maximum water-cement ratio and/or maximum cement
content to give adequate durability for the particular site
conditions.
• Maximum cement content to avoid shrinkage cracking
due to temperature cycle in mass concrete.

CONCLUSION:
The initial findings have shown that the lightweight con-
crete has a desirable strength to be an alternative con-
struction material for the industrialized building system.
The strength of aerated lightweight concrete blocks are
low for lower density mixture. This resulted in the incre-
ment of voids throughout the sample caused by the foam.
Thus the decrease in the compressive strength of the con-
crete.
The foamed lightweight concrete is not suitable to be used
as non-load bearing wall as the compressive strength is
27% less than recommended. Nevertheless the Compres-
sive strength is accepted to be produced as non-load
bearing structure.
As Cellular light weight Concrete Blocks are less in
weights and Densities they can be called as light weight
blocks. Using these blocks can reduce the wall load on
the slabs, which in turn reduces the reinforcement in the
slabs and beams of the structure.
Generally we use can also customize the brick size in CLC
technology which can reduce the work time and wall will
be finished in short time. Construction of walls can also
be done by using wall panels same as the way of doing
shuttering work for the slab.
SCOPE OF FUTURE WORK:
In the future the usage of cellular light weight blocks will
be vast as it has many advantages compared to regular
bricks using in the present market and these bricks are
eco-friendly.
By using the cellular light weight concrete wall can be
constructed by using panels instead of casting blocks
with different mix proportions which is suitable for the
work. Mix proportions for the blocks and panels work
may vary mainly in water cement ratio.
Using the different mix proportions by changing the ce-
ment and fly ash percentages we can make the blocks
which can be used for the works like compound walls,
parapet walls etc. Flooring base course can be prepared
by the Cellular light weight concrete.
Tests like Nail test, water absorption test, thermal con-
ductivity tests can also be done for the blocks if neces-
sary.
In the future usage of Cellular light weight concrete will
increase and many other products can be arrived and
there is scope for constructing a simple non load bearing
structure like an independent house can be done only by
Cellular light weight concrete.
