Green concrete by using high volume slag, recycled aggregate, recycled water to build eco environment

Author(s): Nayana AY, S Kavitha
Abstract: Manufacture and using of Ordinary Portland cement used in concrete industry produces 2.5 billion tons of CO2. Hence several researches are focused on use of waste materials which is having cementing properties, which can be added as a partial replacement of cement in concrete without compromising strength and durability of concrete. This decreases the consumption of cement thus reduction in carbon emission. GGBS is a byproduct, which is obtained by manufacturing of iron, which may be used as partial replacement of cement in concrete. In response to the global warming issues, green concrete for construction is an essential requirement. In the present project, an attempt is made to produce the green concrete by using the by-product GGBS, recycled aggregates and recycled water to reduce the carbon footprints. Firstly, cement is replaced by GGBFS 60%, 70%, 80% by weight and 100% recycled aggregate and 100% recycled water is used. Grade of the concrete is M25. As water is the primary requirement in the world, by using recycled water scarcity of water may be reduced and also Disposal of demolished material is a big issue. Hence recycled aggregate in concrete can be useful for environment protection. This project provides mechanical properties of concrete prepared with ordinary Portland cement and green concrete.
