Abstract :
This paper consists of the experimental results carried out for utilization of waste foundry sand (WFS) in
High strength concrete. The waste foundry sand was replaced in the place of normal sand with four different
percentages (10%, 20%, 30%, and 40%). The several tests such as compressive strength, split tensile strength,
modulus of elasticity, flexural strength, ultrasonic pulse velocity (UPV), rebound hammer test, are performed for 7
days and 28 days to obtain the behaviour the concrete due to foundry sand. The temperature effects of concrete were
observed for the different temperatures such as (200, 400, 600, 800, and 1000℃) for 28 days. In this test results there
is sudden decrease in compressive strength due to the increase in percentage of foundry sand from 30%. But
moreover 10% to 20 % replacement of foundry sand almost have similar strength as to that of the control mixture.
