Silica sand is replaced at 20%, 40%, 60%, 80% and by weight of cement and the results are compared with the strength of conventional concrete. M25 grade concrete is taken for study.

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%, 60% and 70% with natural fine aggregates. For making concrete OPC-53 grade cement is used.

Dolomite-Silica sand is blended with M-Sand in fluctuating extents of 30%, 50%, and 70%. Fresh and Hardened mortar tests had been completed. Compressive and Flexural Brick-Bond Masonry tests have likewise been done. Results demonstrate that Dolomite-Silica Sand can be utilized as a partial replacement for M-sand up to 50%.

Pigments Fig. 1: Silica sand C. Objective and Need of the Study: Partially Replacement of fine aggregate with silica sand by volume. To investigate the fresh and hardened properties (slump test, compressive strength, Tensile strength & Flexural strength) of concrete for M20-M30 grade of concrete mix.
