A Study On The Compressive Strength OF Concrete By Using Silica Fume As A Partial Replacement Of Cement

Abstract

Generally, Portland composite cement is most commonly used making concrete in construction work. A by- product silica fume is partially replaced with concrete to improve the durability, strength and mechanical properties of the concrete. A by-product silica fume are increased the strength and durability of the concrete. Silica fume is added to increase the self- consolidating strength and compressive strength of the concrete. In this present an experimental work which carried out by silica fume as an additional material for cement and determine cement for M20 grade of concrete. We added silica fume in the concrete to replace 0% 10% 20% 30% 40% 50% weight of cement at increase of 10% for cylinder mold and find out the compressive strength after 7 and 28 days. For 7 days the average compressive strength of the concrete to reach 12.00 Mpa. The highest compressive strength of the concrete found 12.00 Mpa. For 28 days the average compressive strength of the concrete to reach 19.84 Mpa. The highest compressive strength of the concrete found 19.84 Mpa.
