-The reduction in the sources of natural sand and the requirement for reduction in the cost of concrete production has resulted in the increased need to identify substitute material to sand as fine aggregates in the production of concretes especially in Concrete. Quarry dust, a by-product from the crushing process during quarrying activities is one of such materials.
Locally available quarry screening (quarry dust) was collected from „stone crusher industry. Quarry dust comprises of the smaller aggregate particles, so it was sieved and quarry dust passing from 4.75mm IS sieve and retaining on 150 micron IS sieve is used for the replacement of fine aggregate. The physical properties
quarry dust as 100% replacement of river sand. Quarry dust can be described as the residue or tailing material after the extraction and processing of rocks and that forms fine particles less than 4.75mm. Quarry dust constitutes 20-25 % of the output of rubble crushing (Information gathered form the quarry …
To overcome this problem, present study is focused on the suitability to utilize the quarry dust in Self Compacting Concrete (SCC) partially as fine aggregate with the natural fine aggregates. In this work, quarry dust is used as replacement of sand in a different level (0%, 15%, 30%, 45% and 60%) for producing the SCC.
Jun 01, 2018 Concrete used was prepared by replacing 25% and 100% of sand by weight with quarry dust. Also, conventional sand concrete was prepared as reference concrete for comparison. 100 mm cube and 100 100 500 mm plain beam specimens were prepared using concrete strengths ranging from 25 N/mm 2 to 47 N/mm 2 for the three replacement levels of 0% ...
shortage in many areas. Quarry dust can be used as an economic alternative to the natural sand. In this investigation an attempt is made to utilize quarry dust as a partial substitute for natural sand in producing concrete. Natural sand is replaced by Quarry dust at an interval of 5%, 10%, 15%, 20% and 25%. Mix proportions for M 20
The replacement percentages of Cement with GGBS are 20 %, 40 % and 60 % by weight and 25 %, 50 %, 75 % and 100 % of Quarry Dust are used as a replacement of Natural Sand. Various combination of GGBS and Quarry Dust were prepared using M30 Grade of Concrete. The effect on these replacement materials on Compressive Strength, Split Tensile ...
Dec 01, 2017 However, concrete with 25% sand replacement gave the highest (7.9% higher than concrete with no sand replacement) modulus of elastic of concrete. The equations to predict modulus of elasticity of quarry dust concrete based on the compressive strength derived in this study varies greatly from those proposed in standard codes of practice.
May 19, 2020 In one more investigation where natural sand is replaced 100% with quarry dust to study the physical properties, mechanical properties and durability of concrete made by quarry dust with done by R. Ilangovana , N. Mahendrana and K. Nagamanib .Mix design has been developed for M20, M30 and M40 grade of concrete for both conventional concrete ...

Jun 06, 2016 Quarry dust uses is not limited to highway projects, in construction projects that involves homes building, it is fast becoming popular too. Partial replacement of sand with quarry dust will make good concrete that is well desired in residential construction. The final product is strong bricks, slabs or tiles that are produced at lower cost ...
utilization of Quarry Dust by replacing sand would also reduce the pollution in environment and also reduce the cost of concrete. Keywords: - Quarry dust, Sand, Concrete, Compressive strength. INTRODUCTION:- Quarry dust is a byproduct of the crushing process which is a concentrated material to use as aggregates for
Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be replaced to the amount 25%. Its Availability is not a concern.
From the results, the concrete with 50% of quarry dust as partial replacement of river sand was selected as optimum percentage and used for further experiments. III. Optimization of Silica fume . After getting the optimum percentage of QD as 50%, 3 mix proportions have been prepared having QD as 40%, 50% and 60%.
Dec 01, 2020 The quarry dust has been used as a partial replacement for cement proportion at different levels of replacement (25%, 30% and 35%). Quarry dust was used as the main material in this project to measure the effectiveness of concrete performance. In this research, the quarry dust composition was determined by using X-Ray Fluorescence Spectrometer ...
determine the compressive strength of foam concrete by using quarry dust as partial sand replacement material. This report presents the feasibility of the usage of quarry dust as 10 %, 20 %, 30 %, 40% and 50% for sand in foam concrete. Mix design was formulated and developed for four different proportion of quarry dust in foam concrete. Get Price
River sand is most commonly used fine aggregate in concrete but due to acute shortage in many areas, availability, cost & environmental impact are the major concern (Ahmed et.al., 1989). To overcome from this crisis, partial replacement of sand with quarry dust can be an economic alternative.
Concrete Cube Made by Using Quarry Dust. The concrete cubes are prepared by using replacement of 10%, 20%, and 30% of quarry dust. These cubes are tested for compressive strength at 3, 7 and 14 days. Three cube specimens were tested at 3, 7, and 14 days in each percentage and obtained the compressive strength. 6.
Experimental Investigation on Replacement of Sand by Graded Quarry Dust in Concrete ... Compressive Strength of Concrete by Using Lateritic Sand and Quarry Dust CEX042. Use of Industrial Waste Red Mud in the Production of Self Compacting Concrete CEX043. Experimental Investigation of Fibre reinforced Concrete ...
According to the value of compressive strength collected, the value is high and it show that quarry dust suitable to use as sand replacement. All the value of compressive strength surpasses the minimum value of compressive strength for normal concrete that is 7N/mm. So, quarry dust can apply as sand replacement in concrete mix for construction industry.
