Performance of Concrete Materials Containing Recycled Aggregate from Construction and Demolition Waste in India

The recycling and reuse of waste concrete in India have gained significant momentum as sustainable construction practices are increasingly prioritized. This abstract provides a concise overview of the current state of recycling and reuse of waste concrete in India, with a focus on the relevant provisions of the Indian Standard (IS) codes. India produces a substantial amount of construction and demolition waste, including concrete. The IS codes, such as IS 2386 Part 1:1963, IS 2386 Part 3:1963, and IS 456:2000, play a crucial role in guiding the testing, evaluation, and usage of recycled concrete materials. IS 2386 Part 1:1963 outlines testing procedures for aggregates, including recycled aggregates derived from waste concrete. These tests assess properties like particle size distribution, specific gravity, water absorption, and crushing strength to ensure the quality and suitability of recycled aggregates. IS 2386 Part 3:1963 provides methods for testing the compressive strength of concrete cubes made with recycled aggregates. This allows for evaluating the structural performance of recycled concrete. IS 456:2000, the Code of Practice for Plain and Reinforced Concrete, includes provisions for using recycled aggregates in concrete. It establishes maximum limits for replacing natural aggregates with recycled aggregates, ensuring the durability and strength of the resulting concrete. While the IS codes provide essential guidance, challenges remain, including awareness among stakeholders, standardized testing procedures, and the development of appropriate recycling infrastructure. In conclusion, adherence to IS codal provisions supports the recycling and reuse of waste concrete in India, promoting sustainable practices and contributing to a greener construction industry.

Effect of using sugar and gypsum as a retarder on concrete properties in Omani weather

This study deals with the retardation of cement setting time and workability in hot weather such as in Sultanate of Oman. Combination of sugar and gypsum was used as retarders. The aim of this study was to investigate the effect of retarders on consistency, setting time of ordinary Portland cement (OPC) paste and compressive strength of concrete cubes after 7 days of curing. OPC paste with a water cement ratio 0.4 to 0.5 was prepared by mixing 500 grams of ordinary Portland cement, a fixed amount of sugar of 0.02% by weight of cement with a combination of different gypsum of 1, 2, 3, 4, and 5% by weight cement and water. Sugar has a strong retarding effect, and this effect, controlled by Gypsum, can shorten the long setting time caused by sugar. The setting time of cement paste was reduced from 5.5 hours to 3 hours with an increase in Gypsum at a fixed amount of sugar. At a constant sugar content, increasing the gypsum content reduced the compressive strength from 31.5 MPa to 30.92 MPa.

Strength and durability characteristics of concrete blended with micro level fibres

Concrete is among the most used building materials, which is often produced using materials that are readily available locally. To fulfill the demands of modern building, the current trend in concrete technology is to make concrete stronger and more durable. The primary goal of this research is to examine the comparative analysis of mechanical parameters of different size cubes and to determine the durability parameters of concrete of grade M40 incorporated with various dosages of glass fibre and steel fibre in a micro size level. Concrete's durability and brittleness are both improved with the inclusion of fibres for a dosage of 0.1 to 1% of concrete volume. In this investigation we researched the compressive strength variations of 150 mm size cubes and 100 mm size cubes cast with 0.5% & 1% addition of glass and steel fibre. The ultimate compressive strength of concrete cubes with 1% addition of glass fibre at 28 days of curing is 49 MPa and 51 MPa for 150 mm size and 100 mm size cubes respectively. The various mix proportions are tested for different durability tests like acid resistance test, sulphate attack test, alkalinity of concrete and water absorption. The strength loss of mix with 0.5% addition of glass and steel fibres due to acid attack are 19% and 19.2% which is low compared to control concrete. Also the average strength loss of mix with 1% addition of glass fibre is low when compared to other mixes in a sulphate environment. The water absorption percentage is low for concrete mixes blended with glass fibres. The alkalinity of concrete varies with pH of 10.5 to 9.5 for various mixes. Through this experiment, it was discovered that glass fibre blended concrete outperformed control mix and mixes with steel fibres in terms of all strength and durability metrics.

An Engineering study was carried out for five stations in the Lower Zab basin, southwest of Kirkuk, to determine the viability of the Quaternary age sediments for concrete works. The geotechnical evaluation results included that the coarse aggregate's grain size analysis is identical to the gradient class (63.0 mm) according to the [1] classification. As for the gradation of fine aggregate for the sediments of the study area, the results of the granular gradient of the samples after matching them with the limits of AASHTO specification showed that they are identical to the specification with slight differences on some sieves. The elongation and flatness tests showed that the highest percentage of the longitudinal shape is (19.2%) and flat-shaped particles is (28.8%), within permissible limits according to British standard [2], the specific gravity for coarse aggregate was between (2.60 - 2.64) and saturated specific gravity (2.61 - 2.65), and the values of specific weight for fine soil ranged from (2.72 - 2.64) which is suitable for use in concrete works. The results of the laboratory test of the durability tests - The Los Angeles test for the samples showed that the highest percentage for weight loss was (20%), which is suitable for use in the concrete according to the Iraqi standard [3], the results of the laboratory test for stability showed that the percentage of weight loss for coarse aggregate (gravel) by the effect of sodium sulfate solution and for the number of 5 cycles of the samples ranged between (8.3% - 4.1%), which is valid for use in concrete works according to the American specification [4]. The results of the resistance tests - the point load test for stations (S1, S3, S4) within the classification range of very strong - extremely strong, and the two stations (S2, S5) within the class strong - very strong - extremely strong compared to the classification of [5], and they are good for concrete works.

According to the Iraqi standard specification [7], the compressive strength values of the samples are suitable for regular unreinforced concrete, and in comparison with [8] classification, it was apparent that the concrete produced is of moderate endurance. And suitable for concrete works According to [9].

Study on Properties of Concrete After Incorporating Waste Materials

The effects of fly ash, Air Cooled Blast Furnace Slag (ACBFS), and silica fume on cement compressive strength are examined. The compressive strength of cement concrete is studied by the addition of fly ash, air-cooled blast furnace slag (ACBFS), and silica fume. The effect of fly ash, ACBFS, and silica fume on the compressive strength of concrete was investigated. The cement content of the concrete was reduced by 25%, 22.50%, 20%, and 17.50%, respectively; fly ash was used to replace 20%, 40%, and 60% of the coarse aggregate; and fly ash was partially replaced by 2.5%, 5%, and 7.50% of the cement content. Contrarily, fly ash was left out of the mixing process for M30. The compressive strength of concrete cubes and beams aged 7 and 28 days was tested.

Experimental and damage modeling research on compression‐shear behavior of carbon fiber recycled aggregate concrete

AbstractThe application potential of recycled aggregate concrete has been realized with the development and utilization of waste concrete. Fibers are added to concrete made with recycled coarse aggregate to enhance its mechanical properties and broaden its application possibilities. Additionally, in practical applications, parts of structural elements are frequently under compression‐shear stress. As a result, the normal stress ratio k (k = σ/fcu, where σ is axial compressive stress, and fcu is concrete cube compressive strength), coarse aggregate replacement rate, and carbon fiber content are used as design parameters to examine the compressive‐shear mechanical properties of carbon fiber recycled aggregate concrete in this paper. The results show that the normal stress ratio and fiber content affect the whole compression‐shear process curve, shear strength, peak shear displacement, and damage evolution. A compressive shear damage model that takes into account the aggregate replacement rate, normal stress ratio, and fiber content is established. And there is good agreement between the experimental findings and the calculation model.

Bearing Capacity of UHPC-Filled High-Strength Elliptical Steel Tube Composite Columns with Encased High-Strength H-Shape Steel Subjected to Eccentrical Load

In order to investigate the bearing capacity of composite columns composed of ultra-high performance concrete, (UHPC)-filled high-strength elliptical steel tube with encased high-strength H-shape steel (HUCFESTCs) were subjected to eccentric load. Forty-four HUCFESTCs were designed with varying parameters: yield strength of the steel tube (fy), yield strength of the H-shape steel (fy1), concrete-cube compressive strength (fcu), steel tube thickness (t), eccentricity (e), slenderness ratio (λ), the section area of the H-shape steel (AHS), and long–short axis ratio (ψ). Based on a bilinear elastic–plastic constitutive model of steel that considered stress hardening and a nonlinear constitutive model of UHPC, 44 HUCFESTCs models were established by ABAQUS software. The influence of different parameters on the ultimate bearing capacity of the HUCFESTCs was analyzed. The whole process of HUCFESTCs under eccentric load was studied, and the typical failure modes of HUCFESTCs are described. The results show that the main failure mode of the HUCFESTCs subjected to eccentrical load is bulging outward of the steel tube, the buckling of the H-shape steel, and crushing of the concrete in the middle part of the column and the inner part of the H-shape steel. The stiffness of HUCFESTCs increases gradually with the increase in fy, t, and e. The ultimate eccentrical compression bearing capacity of HUCFESTCs improves gradually with increases in fy, t, fy1, AHS, ψ, and fcu, but it decreases gradually with increases in λ and e. By using statistical regression and introducing the reduction coefficient of eccentricity, the calculation formula for the eccentric bearing capacity of HUCFEST columns is developed, which can provide a basis for the application of HUCFESTCs in practical engineering.

Analysis of Cube Compressive Strength on Concrete with Recycled Aggregate and Rubber Particles

This paper analyzed the cube compressive strength of concrete containing recycled aggregate as part of coarse aggregates and rubber particles as part of fine aggregate, simultaneously. The effect of content of both aggregates on concrete compressive strength was studied. 25 sets of samples were made with a constant water/cement ratio of 0.39. Cube compressive strength of different samples at age of 28 days were obtained in accordance with relevant standard. Influence of replacement ratio of recycled aggregate and rubber on strength was investigated basing on the analyses of testing data and microstructure inspections, respectively. Results indicate that both recycled aggregate and rubber particles weaken the compressive strength of concrete while rubber particles plays a more important role. Replacement of fine aggregate over 20 vol% by rubber particles should be used carefully.

Destructive and Non-Destructive Testing of the Performance of Copper Slag Fiber-Reinforced Concrete.

Concrete technology is adopted worldwide in construction due to its effectiveness, performance, and price benefits. Subsequently, it needs to be an eco-friendly, sustainable, and energy-efficient material. This is achieved by replacing or adding energy-efficient concrete materials from industries, such as ground granulated blast furnace slag, steel slag, fly ash, bottom ash, rice husk ash, etc. Likewise, copper slag is a waste material produced as molten slag from the copper industry, which can be used in concrete production. Copper slag can perform roles similar to pozzolans in the hydration process. This paper extends the comparative study of copper slag concrete with polypropylene fiber (PPF) subjected to destructive and non-destructive testing. Under destructive testing, compressive strength of concrete cubes, compressive strength of mortar cubes, splitting tensile tests on cylindrical specimens, and flexural tests on plain cement concrete were conducted and analysed. Ultrasonic pulse velocity and rebound hammer tests were performed on the samples as per IS13311-Part 1-1992 for non-destructive testing. The 100% replacement of copper slag exhibited a very high workability of 105 mm, while the addition of 0.8% PPF decreased the flowability of the concrete. Hence, the workability of concrete decreases as the fiber content increases. The density of the concrete was found to be increased in the range of 5% to 10%. Furthermore, it was found that, for all volume fractions of fiber, there was no reduction in compressive strength of up to 80% of copper slag concrete compared to control concrete. The 40% copper slag concrete was the best mix proportion for increasing compressive strength. However, for cement mortar applications, 80% copper slag is recommended. The findings of non-destructive testing show that, except for 100% copper slag, all mixes were of good quality compared to other mixes. Linear relationships were developed to predict compressive strength from UPV and rebound hammer test values. This relationship shows better prediction among dependent and independent values. It is concluded that copper slag has a pozzolanic composition, and is compatible with PPF, resulting in good mechanical characteristics.

Study on strength formation and frost resistance of concrete modified by molybdenum tailings

Solid waste tailing materials from molybdenum mining in China occupy extensive land areas and threaten the health of nearby residents. To address the risk and the increasing shortage of natural construction materials, using those tailings as a construction material is a potential option for the construction industry. Modified concrete mixed with other tailings materials has been widely studied. The application of molybdenum tailings modified concrete to cold regions needs to fully consider its durability. Through the concrete cube compressive strength test and rapid freeze-thaw cycle test after different standard curing time, the strength formation process and frost resistance of molybdenum tailings modified concrete are explored. On this basis, the optimal content of Mo tailing material was determined. Results demonstrated that the compressive strength and frost resistance of Mo-tailing-modified concretes increased first and then decreased with the increase in Mo tailing content. The optimal modification effect was achieved when the Mo tailing content reached 20%. Under that circumstance, the porosity of Mo-tailing-modified concrete was at a minimum before and after the freeze–thaw cycles, thus increasing mechanical and antifrost properties significantly.

Compressive strengths of concrete by partially replacing sand with iron-ore waste

Sand is extracted at a rate more than its restoration. Nevertheless, the availability of sand in the growing demand of the construction industry remains a challenge due to cost and quality problems. This study investigates the compressive strength of concrete by partially replacing sand with iron-ore waste. Experimental investigations were conducted to study the compressive strength, physical, mechanical and fresh property of concrete containing iron-ore waste. During the experiment, concrete cubes were prepared with 10-100% composition of iron ore waste to evaluate their compressive strength. Results from the experimentation revealed that, concrete cubes prepared by partially replacing sand with iron ore waste often yield a better compressive strength than a conventional concrete. More so, the densities of concrete cubes were observed to remain consistent but increased slightly, notably at 10% and 20% of waste replacement. Meanwhile, at 30% waste replacement, there was reduction in compressive strength at 28days curing age and this reduction continued as percentage iron ore increased towards 100%. Also, increase in compressive strength of concrete cubes was observed at 10-20% sand replacement with iron ore. It was therefore established that concrete produced under 10% and 20% replacement, can be utilized for all construction purposes requiring concrete.

Experimental study on surface wrapping strengthening of EPS particles and its concrete performance

Abstract Expanded polystyrene (EPS) concrete is a low-carbon green building material, which has the properties of thermal insulation, but its strength is not high at present. To improve the strength of EPS concrete, EPS particles were wrapped on the surface by magnesium phosphate cement, ultra-high performance concrete, and waterborne polyurethane, they were used to make concrete after aging, and then the strength and microproperties of concrete were tested. The test results show that the wrapping material form a shell structure on the surface of EPS particles; the hydrophilic property of the wrapped EPS particles and the uniformity of the concrete have been significantly improved; the contact between the wrapped EPS particles and the cement base has become more closer; the cube compressive strength of concrete is increased by 80–110%, the flexural strength of concrete is increased by 40–90%. The research results of this study are of great significance for EPS concrete used as structural material and fabricated lightweight wallboard.

Strength Characteristics of Rice Husk and Corn Cob Ash Blended Cement Concrete

The study investigates the mechanical properties of concrete incorporating Rice husk Ash (RHA) and Concorb Ash (CCA) as cementitious binders. Concrete cubes was prepared from a standardized prescribed mix of 1:2:4. The cement component in the reference mix was replaced with combined % weight of rice husk ash and corncob ash. The physical and chemical composition of RHA and CCA were examined as well as the workability and compressive strength properties of varying percentage of RHA and CCA blended cement concrete. Water–cement ratios of 0.6, was adopted for the reference and blended mixes. A total of 75 concrete cubes of different percentages by weight of combination of RHA and CCA to Portland cement in the order of 0%, 10%, 20%, 30%, and 40% were cast. The strength measurements of concrete were performed at the ages of 7, 14, 21, 28 and 56 days. The results revealed that compressive strength increased with increase in curing age but decreased as the RHA and CCA contents increased. The compressive strength of concrete cubes with the combination of RHA and CCA was lower at early stages but improves significantly up to 56 days. The highest compressive strength was 22.94N/mm2 and 26.27N/mm2 at 56 days for 0% and 10% combination of RHA and CCA respectivelyBased on the test results the study concluded that 10% RHA and CCA content is adequate as supplementary cementitious material for blended concrete.

Manufactured sand for the development of reinforced concrete spun pipes

Due to overexploitation of natural resources, the deficiency of river sand as a fine aggregate is a major problem and manufactured sand is replaced as a suitable alternative material. This paper investigates the influence of Manufactured sand as a replacement for fine aggregate material in the manufacture of RCC spun pipes. M35 grade concrete is prepared with cement, coarse aggregate, superplasticizers, and river sand is replaced with 50%,75% and 100 % manufactured sand. Test results shows that the compressive strength of concrete cubes with 50% replacement levels leads to higher compressive strength at early ages, and their reactivity decreases at later age strength. Test conducted on concrete pipes reveals that the load-carrying capacity of pipes with 50% replacement levels increases and delays the crack formation on the surface and postponed the ultimate failure. Similarly, the hydrostatic test also shows positive results with the addition of MSand. The cost of Manufactured sand is lower than the river sand and it is free from impurities such as silt and clayey matters and it gives a possible solution to the shortage of fine aggregate in the production of RCC pipes.

Health monitoring of cracked concrete structure by impedance approach

Cracks/damages in concrete structures are the core concern for reduction of service life of infrastructures. Therefore, the effective technique is required for the prevention of cracks growth to improve the durability of structures. The cracks growth can be minimised by the incorporation of bacteria in the cementitious materials. The development of calcium carbonate heals the cracks automatically without any kind of human effort. The health of structures can be monitored and the presence of damages/cracks can be determined using various structural health monitoring techniques. In this paper, the research is focused on the monitoring of concrete cubes to explore the effect of bacteria. Two types of cube specimens were considered such as control concrete and bacterial concrete cubes, respectively. The six cubes of control concrete and six cubes of bacterial concrete of dimension 150 × 150 × 150 mm were cast. The compressive load of 300 kN was applied on control concrete cubes and bacterial concrete cubes to induce the incipient cracks/damages. After inducing the damages in the cubes, these cubes were tested after 7 days and 28 days curing. It was observed that the compressive strength of bacterial concrete was increased with respect to the control concrete by 19 % and 23 % at 7 and 28 days, respectively. The Electro-Mechanical Impedance (EMI) technique was used for monitoring the development of strength in both the cubes continuously. Piezo-ceramic lead Zirconate Titanate (PZT) patches were used to extract the signature. Admittance signatures were determined to access the health of cube specimens. Any deviation in signature from the healthy state that is baseline signature designates the change in compressive strength of concrete cubes. The increased strength was quantified in terms of signature change. The proposed investigation is applicable for monitoring of bacterial concrete structures. The research paper will be resulted new research directions and develop sustainable advancements in concrete technology.

Experimental Studies on Strength Properties of M60 Concrete with Partial Replacement of Cement by GGBS and Fly Ash

Abstract: Among all the current construction materials, concrete occupies a unique position. Concrete is the most often utilised building material. Cement production emits CO2, which is harmful to the environment. One of the most crucial ingredients in concrete production is cement. Experiments were carried out to see how different percentages of Fly Ash and GGBS affected the mechanical qualities of M60 grade concrete. After 7, 14, and 28 days of curing, the compressive strength of concrete cubes with suggested replacement was determined. Compressive strength, split tensile strength, and flexural strength are all evaluated on the cubes, cylinders, and prisms. The primary goal of this study is to compare the fresh and hardened characteristics of M-60 grade control concrete with concrete prepared with varied ratios of fly ash and GGBS Keywords: GGBS, Fly Ash, Durability, Compressive Strength, Tensile Strength, Flexural Strength, Slum cone Test

Hysteretic Behavior on Asymmetrical Composite Joints with Concrete-Filled Steel Tube Columns and Unequal High Steel Beams

In order to acquire the hysteretic behavior of the asymmetrical composite joints with concrete-filled steel tube (CFST) columns and unequal high steel beams, 36 full-scale composite joints were designed, and the CFST hoop coefficient (ξ), axial compression ratio (n0), concrete cube compressive strength (fcuk), steel tube strength (fyk), beam, and column section size were taken as the main control parameters. Based on nonlinear constitutive models of concrete and the double broken-line stress-hardening constitutive model of steel, and by introducing the symmetric contact element and multi-point constraint (MPC), reduced-scale composite joints were simulated by ABAQUS software. By comparing with the test curves, the rationality of the modeling method was verified. The influence of various parameters on the seismic performance of the full-scale asymmetrical composite joints was investigated. The results show that with the increasing of fcuk, the peak load (Pmax) and ductility of the specimens gradually increased. With the increasing of n0, the Pmax of the specimens gradually increases firstly and then gradually decreases after reaching a peak point. The composite joints have good energy dissipation capacity and the characteristic of stiffness degradation. The oblique struts force mechanism in the full-scale asymmetrical composite joint domain is proposed. By introducing influence coefficients (ξ1 and ξ2), the expression of shear bearing capacity of composite joints is obtained by statistical regression, which can provide theoretical support for the seismic design of asymmetrical composite joints.

COMPRESSIVE STRENGTH BEHAVIOURS OF LAGOON–WATER CURED CEMENT-ALUMINIUM DROSS CONCRETE

This study investigates the compressive strengths of concrete cubes and reinforced columns cast with partial replacement of cement using 0- 25 wt.% Aluminum dross (AlDr) and cured in Lagoon water for 7-42days and 1-6 months respectively. The results indicated cubes with 5 wt.% AlDr, 10 wt. % AlDr and control possess strength of 15N/mm2,14.59N/mm2 and 13.48N/mm2 respectively at 28-day curing while at 42-day the results are 16.89N/mm2, 12.22N/mm2 and 16.96N/mm2 for control, 5 and 10 wt.% AlDr respectively. The 42-day compressive strength (79.48%) confirmed the performance at 28-day strength (75%). Control cube (74.6-95.5%) has higher crystallinity compared to cement (65.1-90.1%) and AlDr (62.4-74.0%) but at 15 wt.% AlDr concrete the crystallinity (78.1-96.2%) is superior with marginal crystal sizes variation (12.8-16.9). The strength (~9.5 N/mm2) with 10 wt. % AlDr column cured for 6 months was better than the control columns environment (~7 N/mm2) at 2-month.

Experimental Study on Slump and Strength Properties of Concrete by Replacement of Cement Using Banana Leaf Ash

Concrete is a composite material, made up of cement, fine aggregates and coarse aggregates. Cement is a basic constituent of concrete and it acts as a binding material. A major drawback in cement is that it emits Carbon dioxide in to the environment. Cement industry serves as the primary producer of carbon dioxide, a potent greenhouse gas. This project is directed to replace the cement in concrete partially by naturally available agro based materials. Here, the cement in concrete is replaced using banana leaf ash . Banana Leaf ash is finely powdered in to ash of fineness more or less equal to the fineness of cement. It is then added to the concrete mix of grade M25 partially by replacing 10% to the mass of cement. The properties and performance of the concrete (i.e., fresh and hardened properties of concrete) are examined before and after the replacement of banana leaf ash and reported. Workability, which is a property of fresh concrete, is estimated with the help of slump cone test. The workability value obtained for normal conventional concrete is low and with the banana leaf ash replaced concrete is medium workability. The compressive strength of concrete cubes is tested after period of 7, 14 and 28 days of curing. As a result, the compressive strength of the conventional M25 grade concrete at 7, 14 and 28 days are found to be 16.75Nmm-2, 20.17Nmm-2 and 23.41Nmm-2 whereas for concrete with banana leaf ash, the compressive strength is found to be 9.385 Nmm-2, 16.855 Nmm-2 and 26.37Nmm-2 . The increase in strength in banana leaf ash concrete at 28 th day is found to be 12.64%. The replacement of Banana leaf ash in concrete deteriorates the carbon emission and it is also a type of waste management.

Replacement of Sand by Quarry Dust in Concrete

The role of quarry dust in the construction of building and other structures to eliminate the demand of nature sand by using quarry waste to replace the use of natural sand. We are investigating the potential of using quarry waste and its effect on the strength and workability of concrete. Initially cement concrete cube was studied with various proportion of cement concrete +quarry dust (M20 & M25). The experimental result showed that the additional of quarry dust as fine aggregate ratio of 30%, 40% and 50% was found to enhance the compressive properties. The compressive strength of concrete cubes at the age of 7 and 28 days were obtained at room temperature. These raw materials of concrete, i.e., river sand and gravel, are also struggling to cope with the rapidly growing demand in many areas around the globe. The sources of good quality river sand and gravel are depleting very fast. According to United Nations Environment Program (UNEP) report, “Sand-rarer than one thinks”, published in March2014, sand and gravel has now become the most widely used natural resource on the planet after water. These are now being extracted at a rate far greater than their renewal. Crushed sands, fine aggregate produced from stone crushing, has become very popular in areas where natural sand is not abundantly available or where there is scarcity in the supply of natural sand. The Mumbai-Pune express highway was a project, where there is a difficulty in procurement of natural sand. This made the construction company to use crushed sand for making approximately 20 lakh cum of concrete necessary for the construction. However, such type of sands contains a large amount of micro-fines, i.e., particles finer than 75 microns, which can have an adverse effect on properties of concrete. So proportioning of different raw materials at the time of mix design is very important, when crushed sand is used in concrete The availability of sand at low cost as a fine aggregate in concrete is not suitable and that is the reason to search for an alternative material. Quarry dust satisfies the reason behind the alternative material as a substitute for sand at very low costIt is found that 40% replacement of fine aggregate by quarry dust gives maximum result in strength than normal concrete and then decreases from 50%. The compressive strength is quantified for varying percentage and grades of concrete by replacement of sand with quarry dust.
