A total of 32 cubes (150×150×150mm) were cast to permit the compressive strength to be observed at 7, 14, 21 and 28 days. Test results revealed that concrete produced from unwashed gravel has a better workability than crushed granite. Higher compressive strength at all period was observed with concrete produced from granite …
The results publicized that by taking 0% to 25% of Fly ash to the weight of cement that specimen when compared with conventional concrete the compressive strength is increased 32.63% by replacement of cement with 10% of Fly Ash for 28 days.

Quarry powder has been shown to boost the compressive durability of concrete. Mix M4 has split tensile durability of 3.9 ± 0.15 MPa and flexural durability of 3.6 ± 0.10 MPa when evaluated. Untreated sea sand and quarry powder will be better able to be used as a substitute building material as a result of this study's findings.
The paper presents results of study on concrete using quarry dust to replace sand at levels of 0%, 25%, and by weight. Design mixes were prepared to achieve concrete grades C25, C30, C35, C40 ...
It is reported that a significant improvement in compressive strength was observed on 10% replacement of cement by MK. The combined effect of flexural and compressive strength of concrete improved with the 15% replacement of cement. The optimum usage of MK was limited to 10–20% of cement [ 30 ].
Sand is often utilized as a fine aggregate in concrete, contributing 22 to 62% of the total mass. The quantity and features of sand in concrete have an impact on its workability, mechanical characteristics, and durability. Effective replacements are needed as natural silica sand becomes scarcer. By incorporating these by-products into concrete, …
