Study on the Effect of Replacement of Cement with Silica Fume Along With Recycled Aggregate
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 9
Abstract
Construction industry is witnessing a tremendous growth year by year. The increase in demand of the construction is causing many environmental impacts. To spot an example, 1 ton of cement production releases 1 ton of CO2 to the atmosphere. Apart from cement aggregate is an important constituent of concrete and extensive mining of the sources of aggregate is causing an ecological imbalance. Ecological sustainability and sustainable construction has to be given prior importance. This paper deals with the partial replacement of cement with silica fume and using a percentage of recycled aggregates as coarse aggregates. Experimental program includes two stages. In the first stage cement is replaced with 5%,7.5%,10%,15% silica fume and its percentage is optimised and in the second stage, with that optimised percentage of silica fume recycled aggregate is varied with 20%, 30% and 40%. Strength parameters studied includes compressive strength, flexural strength, split tensile strength.
