Abstract :

A study is conducted to determine the engineering properties viz. Compressive Strength, and water absorption capacity by partial replacement of river sand in concrete. In recent days the demand for river sand is increasing due to its lesser availability. Hence the practice of partially replacing river sand with lime stone powder is taking a tremendous growth. It is also inferred from the literature that partially replacement of normal river sand with lime stone powder produces the appreciable increase in compressive strength by different variation of percentages of limestone powder replaced. The lime stone powder obtained from limestone quarries. The concrete are made using varying contents of lime stone powder as fine aggregate in ordinary Portland cement. The concrete cubes of M20 grade are made. It was found that at 0.50 water/cement ratio higher compressive strengths are obtained of concrete, and better workability for M20 mix, proportion. These results compare favorably with those of conventional concrete. The concrete was found to be suitable for use as structural members for buildings and related structures.
