This experimental investigation was carried out to evaluate the compressive
strength of concrete mixtures in which Silica Fume was added to Ordinary Portland cement
containing and Manufactured Sand. Cement was replaced with two variations of Silica Fume
by 6% and 8% and River Sand was replaced by Manufacture Sand in variations of 0%, 10%,
20%, 30%, 40%, 50%, 60%. Fourteen concrete mixes were prepared. Slump test was
performed to evaluate fresh behavior of the mix and compressive strength test was carried at
various ages to evaluate strength at 7 and 28days. The results showed significant
improvement in strength property at all ages because of the addition of silica fume to
Ordinary Portland cement.
