This study aims to explore the potential benefits and challenges associated with incorporating silica sand as a fine material in concrete mixtures. Silica sand, known for its abundance and consistent particle size distribution, presents an opportunity to enhance concrete properties while potentially reducing costs. Through a series of laboratory experiments, this research will examine the impact of varying silica sand proportions on concrete's mechanical properties, durability, workability, and sustainability aspects. The findings will provide insights into optimizing concrete mix designs to leverage the advantages of silica sand, paving the way for more efficient and sustainable construction practices. The use of alternative aggregate like silica sand is a natural step in solving part of depletion of natural aggregates. The investigation on alternative material for concrete making started before half a century. Concrete made from silica sand waste as fine aggregate was studied for workability, compressive strength, Split tensile strength and Flexural strength. Further, study of its durability will ensure greater dependability in its usage. So here in this project, Silica sand had been used as replacement of fine aggregate by different percentage for making concrete of M-20, with w/c ratio 0.50 & 0.45. The percentage replacement will be 0%, 10%, 20%, 30%, 40%, 50% with natural fine aggregates. For making concrete OPC-53 grade cement is used. Cubes and beams will be casted and tested compressive strength, Split tensile strength, and flexural strength as well as for durability properties. Optimum replacement of silica sand can be used in structural concrete.
