混凝土是建筑行业常用的材料。混凝土中广泛使用的原材料有水泥、细骨料、粗骨料和水，其中常见的细骨料是河砂。但是，现在的河砂是在很大的速度消耗和膨胀，由于这是一个有效的替代品的需要。采石场粉尘已被发现是沙子的经济替代品。本文对采石场石粉部分替代混凝土中细骨料的研究进行了探讨。M20级混凝土配合比设计采用IS设计，适用于常规混凝土和替代配合比。在立方体、圆柱体和梁上制备了常规和20%、40%、60%采石场粉尘替代的试样。固化28天后，对试样进行测试，以达到其最大的压缩，拉伸和弯曲强度。绘制图表，并将结果与控制混合物进行比较。结果表明，用采石场粉尘有效地替代砂是可能的。
Concrete is the commonly used material in the construction industry. The widely used raw material in the concrete are cement, fine aggregate, coarse aggregate and water, of this common river sand is used as fine aggregate. But, now-a-days river sand is at great rate of depletion and expansive, due to which there was a need for an effective alternative. Quarry dust, has been found as an economic alternative for sand. In this paper, we have investigated the study of quarry rock dust as partial replacement of fine aggregate in concrete. Mix design has been developed for M20 grade using IS design for conventional concrete and replaced mix. Specimens on cubes, cylinders and beams were prepared for both conventional and 20%, 40%, 60% replacement with quarry dust. Tests were conducted on the specimens after 28 days curing to attain its maximum compressive, tensile and flexural strength. Graphs were drawn and results were compared with controlled mix. It is found that the effective replacement of sand with quarry dust is possible.
