Sustainable Consideration of Concrete using GGBFS and Fly Ash

Abstract

Abstract: The economy of the nation is significantly influenced by the construction industries. The most common material used in construction is concrete. The fundamental components of concrete are cement, sand, aggregate, and water. Cement is the primary binder in concrete. 10% to 15% of the total volume of concrete is made up of cement. Large amounts of CO2 gas are released during cement production, which is very harmful to the environment. According to several studies conducted, waste products or by-products such as Fly Ash, GGBFS, silica fume, metakaolin, etc., can be employed as a cement substitute. In this study, the experimental evaluation of the compressive strength of concrete for M25 grade concrete using partial cement replacement with 10%, 15%, 20%, and 25% of GGBFS and Fly Ash is presented. For all blends, a W/C ratio of 0.5 is used. When the concrete has been cast and given a 7 and 28 day curing period, testing has been conducted. The possibility of using waste material in structural cones is the main topic of this study. Reduced cement use will result in less CO2 being produced, which will help to preserve the environment and be cost-effective. The use of industrial waste has evolved as aggressive construction material, thus feature as Sustainable construction.
