Study Towards Green Concrete for Better Sustainable Construction

Abstract

Concrete which has been made from waste of concrete that are eco friendly is termed as green concrete. 8 to 10% of world total CO2 emission comes from production of cement, when lime stone and crushed clay are heated at high temperature during the production. Green concrete uses waste material at least one of its component and environment destruction did not occur during the time of production. Researchers have conducted various experiments to find perfect solution for sustainable construction and from them green concrete is one. Here an effort has been made to inculcate the ideas about the mechanical and rheological properties of Green Concrete grade M25 by replacing cement with micro silica, fine and coarse aggregates with crushed recycled aggregates and crushed glass from 10 to 30% replacement by weight of the materials. And they have been compared with conventional mixed concrete. It has been observed that when cement, sand and coarse aggregate is replaced by 30% 0f micro silica, 20% crushed recycled aggregates and 30% crushed glass it has shown a better result in mechanical and fresh property with respect to conventional concrete.
