The document experimentally investigates the durability properties of recycled aggregate concrete. Concrete mixtures were prepared with 0-50% replacement of natural coarse aggregates with recycled concrete aggregates. The compressive strength, split tensile strength, density, water absorption, acid resistance, and alkali resistance of the mixtures were tested. The results show that concrete with up to 30% recycled aggregate replacement exhibited comparable or slightly lower compressive and tensile strengths compared to a 100% natural aggregate control mixture. Water absorption generally increased and density decreased with higher recycled aggregate content.
The document studies soil cement blocks used for load-bearing masonry. Soil cement blocks with varying cement contents (6%, 8%, 12%) were tested to examine characteristics like compressive strength, water absorption, pore size, and elastic properties. Testing found that doubling the cement content from 6% resulted in over 2.5 times increase in strength. Water absorption was not greatly affected by cement content, but rate of absorption and pore size decreased with higher cement. Elastic modulus increased over 2 times when cement increased from 6% to 8%, but only marginally from 8% to 12%. The study aims to promote soil cement blocks as a lower-cost and more sustainable alternative to fired clay bricks for housing construction.

Strength behaviour of foundry sand on modified high strength concreteeSAT Journals
Abstract Metal foundries use a large amount of sand as part of the metal casting process. Foundry industries generally recycle and reuse the used foundry sand many times in casting process. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as "foundry waste sand." Like many waste products, foundry sand has beneficial applications to other industries. A mixture of silica sand coated with a thin film of burnt carbon and residual binder with traces of dust is termed as foundry sand. From the previous available literature it was found that replacement of sand by foundry sand by certain initial percentages gives a marginal increase in hardened properties of normal strength concrete. In the present work, fine aggregate is replaced by foundry sand with percentages and tests were performed for hardened properties of modified high strength concrete for all replacement levels.

A Study on self-Compacting Concrete Using Portland Slag Cement with Partial R...IJERA Editor
Concrete plays a vital role as a construction material in the world. In the present scenario, waste materials from various industries are added to the mix. Over 400 million tons of waste materials are being produced by various industries every year. Foundries successfully recycle and reuse the sand many times in a foundry. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as Foundry sand. Foundry sand production is nearly 6 to 10 million tons annually. There is a possibility of substituting natural fine aggregate with waste foundry sand which offers technical, economic and environmental advantages which are of great use in the construction sector. The construction industry is now slowly becoming aware of the environmental issues and other sustainable development issues for cement and concrete industries. It is looking for the ways and means to develop building products, which will increase the life span and quality. This thesis presents an experimental investigation on strength aspects like compressive, split tensile and flexural strength of Self Compacting Concrete (SSC) containing an industrial waste foundry sand. It is used as fine aggregate in varying proportions, replacing the fine aggregate with foundry sand as percentages of 0%, 25%, 50%, 75%, 100%. For this green SCC, all SCC tests are performed as per EFNARC guidelines i.e. slump flow, L-box, V funnel and T50 tests are carried out.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Several concrete mixes were prepared with 0-100% replacement of natural sand by waste tile sand. The mixes were tested for workability, compressive strength, and durability after 28 days of curing. The results showed that replacing natural sand with up to 40% waste tile sand improved the compressive strength by 13.04% and tensile strength by 22.63% compared to the control mix. However, strengths decreased with higher replacement levels above 40%. Therefore, waste tile sand shows potential as a partial replacement for natural sand in concrete.
The document experimentally studies the use of glass powder as a partial replacement for cement in concrete. Glass powder was used to replace cement at levels of 10%, 20%, 30%, and 40% by weight. The compressive, tensile, and flexural strengths of the concrete mixtures were then tested at ages up to 28 days and compared to a control concrete without glass powder. The results showed that glass powder can be used as a cement replacement up to a particle size of less than 75μm to prevent alkali-silica reaction, without negatively impacting the strength of the concrete. Using glass powder as a partial cement replacement provides an environmentally friendly way to utilize waste glass in concrete production.
Comparision of Strength For Concrete With Rock Dust And Natural Sand Concrete...IJERA Editor
The Quarry rock dust can be an economic alternative to the river sand. Quarry Rock Dust can be defined as
residue, tailing or other non-voluble waste material after the extraction and processing of rocks to form fine
particles less than 4.75mm. Usually, Quarry Rock Dust is used in large scale in the highways as a surface
finishing material and also used for manufacturing of hollow blocks and lightweight concrete prefabricated
Elements. This project presents the feasibility of the usage of Quarry Rock Dust as hundred percent substitutes
for Natural Sand in concrete. Design Mix for M30 and M40 has been calculated using IS 10262-2009 for both
conventional concrete and quarry dust concrete. Tests were conducted on cubes, cylinders and beams to study
the strength of concrete by using Quarry Rock Dust and the results were compared with the Natural Sand
Concrete. Cement motor ratios of 1:3 and 1:6 are prepared and observe the percentage of water absorption in
both Quarry Rock Dust and Natural sand for plastering.
A Study on self-Compacting Concrete Using Portland Slag Cement with Partial R...IJERA Editor
Concrete plays a vital role as a construction material in the world. In the present scenario, waste materials from various industries are added to the mix. Over 400 million tons of waste materials are being produced by various industries every year. Foundries successfully recycle and reuse the sand many times in a foundry. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as Foundry sand. Foundry sand production is nearly 6 to 10 million tons annually. There is a possibility of substituting natural fine aggregate with waste foundry sand which offers technical, economic and environmental advantages which are of great use in the construction sector. The construction industry is now slowly becoming aware of the environmental issues and other sustainable development issues for cement and concrete industries. It is looking for the ways and means to develop building products, which will increase the life span and quality. This thesis presents an experimental investigation on strength aspects like compressive, split tensile and flexural strength of Self Compacting Concrete (SSC) containing an industrial waste foundry sand. It is used as fine aggregate in varying proportions, replacing the fine aggregate with foundry sand as percentages of 0%, 25%, 50%, 75%, 100%. For this green SCC, all SCC tests are performed as per EFNARC guidelines i.e. slump flow, L-box, V funnel and T50 tests are carried out.

This document summarizes an experimental investigation on concrete with coarse aggregate replaced with waste concrete aggregate. Concrete mixtures were prepared by replacing the natural coarse aggregate with 10%, 20%, 30%, and 40% waste concrete aggregate. The compressive strength and flexural strength of the concrete mixtures were then tested at various curing ages. The results showed that concrete mixtures with up to 30% replacement of natural aggregate with waste concrete aggregate exhibited similar strength properties. However, strength was reduced with 40% replacement, with the 40% replacement concrete showing a 14.36% lower compressive strength and 27.45% lower flexural strength compared to the natural aggregate concrete. Therefore, the study concluded that up to 30% replacement can be considered optimal without comprom

This document presents the results of an experimental study on using quarry dust to replace sand in concrete. Quarry dust is a byproduct of the stone crushing process and can be used as a substitute for natural sand. The study tested different ratios of sand to quarry dust in concrete mixes to determine the optimal replacement ratio. Tests were conducted to measure the workability, density, and compressive strength of concrete mixes with 0-100% replacement of sand with quarry dust. The results showed that replacing up to 40% of sand with quarry dust increased the density and compressive strength of the concrete while still maintaining adequate workability. Replacing sand with quarry dust up to 40% produced equivalent or better results compared to

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

-----------------------------------------------------------------------------***--------------------------------------------------------------------------
Abstract—As a building material, the construction
industry consumes a considerable amount of natural
resources such as sand, gravel, crushed rock, and so on.
Aggregate is the most important component in concrete,
accounting for more than 70% of the matrix. Because of
the wide usage of concrete, mortar, and plastering
materials, the global use of natural sand is extremely large.
To examine the applicability and truthfulness of the Plain
cement-Natural sand mortar using Manufactured Sand,
Silica Sand, and Blast Furnace slag Sand in Indian climatic
circumstances, an analytical and experimental
examination was carried out. For the current study, four
distinct products from market leaders were investigated,
along with a control mortar.
Keyword: Natural sand, Manufactured Sand, Silica Sand,
Blast Furnace slag Sand, Suitability, ANSYS
1. INTRODUCTION
Cement mortar is a compound made by mixing cement,
a good amount, and water. Aggregates have a major impact
on both mechanical and rheological properties of cement
mortar. Materials such as particle size distribution, specific
gravity, shape, and surface roughness all have a significant
impact on the characteristics of the new mortar.
Mineralogy, modulus flexibility, durability, and aggregate
conversion rate are all known for influencing their
properties in a strong way. Sand mining has been banned
due to adverse impacts and environmental inequalities
caused by the removal of sand from rivers. As a result, the
price of natural sand has risen sharply. Under these
circumstances, the search for a viable alternative to
natural river sand that does not endanger the strength and
resilience of the mud becomes critical to allow for the
growth of the infrastructure while protecting the
environment.
One or more layers of mortar may be applied to a concrete,
brickwork, stone masonry or lathing surface for plastering.
It must be long-lasting and resistant to moisture
infiltration, as well as weather uniformly. It should also be
visually appealing. These attributes are determined by the
materials used, the mix composition, the degree of
mechanical bond between the plaster and the backing
surface, and the craftsmanship. Plastering does not
immediately increase structural member strength, but it
does help to keep the structure in good serviceable
condition until failure.
1.1. Natural River Sand
After washing it with clean water, natural sand with a 2.78
coneness module and compliant with zone II as defined by
IS: 383-1970 was used for testing. The gravitational pull of
this natural sand is estimated to be 2.55. The water
absorption rates and the moisture content of the used sand
were found to be 6 percent and 1.0 percent, respectively.
Due to a few of the above problems, natural sand (NS) is
weak in many respects when used for concrete production.
1.2 Manufactured Sand
Manufactured Sand (MS) is a product of crushing and
quarrying. As the aggregates are ground, the quarry is
produced in large quantities. Crushed stone sand, stone
sand, crushed sand, and fine crushed compound are some
of its names. Quarter finishes are a mixture of particles of
coarse sand, medium, and fine sand, and part of the clay /
mud known as the 'filler' range. The industry defines filling
equipment equipment as less than 0.075mm (75 microns)
in size.
1.3 Silica Sand
Limestone with silica and amounts of coal, clay, and other
minerals is what is known as silica sand. Quartz sand and
industrial sand are typical names for this material, which is
frequently employed in a wide range of construction
projects. Rust can be triggered by the presence of silica
sand in metal items. Many industrial applications use silica
sand based on the grain size and form of the sample being
used.
1.4 Blast Furnace slag Sand
The blast furnace is a metal mold that lowers the metal
into molten metal in the presence of coke and fluxes. In
addition to molten metal, the furnace produces slags
