Comparative Study on Strength of Concrete by Partial Replacement of Fine Aggregate by Using M-Sand and Crushed Spent Fire Bricks

Abstract

Aggregates are the important constituents in the concrete composite that help in reducing shrinkage and impart economy to concrete production concrete is the most undisputable and indispensable material being used partial or full replacement of fine aggregates by the other compatible materials like sintered fly ash, crushed rock dust, quarry dust, glass powder and others are being researched from past two decades, in view of conserving the ecological balance. In this direction, an experimental investigation of strength was undertaken to use “Crushed Fire Bricks”, “M-sand” for partial replacement of fine aggregate in concrete.
