A STUDY ON CRUSHED SAND AS AN ALTERNATIVE FOR NATURAL SAND IN HIGH PERFORMANCE CONCRETE

The main objective of this study is to examine the strength of High Performance Concrete using Crushed Sand (Manufactured sand). The natural sand was replaced by Crushed Sand in the proportion of 0%, 20%, 40%, 60%, 80% and 100%. A series of experiments were conducted in M60 grade HPC concrete to study the compressive strength, flexural strength, splitting tensile and modulus of elasticity. Water cement ratio is 0.32 and 10% of silica is also added. Based on the experimental results the replacement by 60% Crushed Sand exhibited the highest compressive strength.
