ENHANCING CONCRETE FLEXURAL STRENGTH: REPLACING CEMENT WITH FLY ASH AND BRICK KILN DUST

Abstract

Concrete is now an essential building material for creation of any type of structural elements, including inflexible pavement as well as beams, columns, slabs, bridges, and girders. Cement is the most essential binding component in the manufacture of concrete because, when combined with water, it can bind both Coarse Aggregate (CA) and Fine Aggregate (FEA). The terms (BKD and FA, which have certain binding qualities when mixed with water, are waste products, as indicated by the paper's title. The researcher's objective is to show how FA and BKD mixed in the percentages of 0%, 10%, 20%, 30%, and 40% are used to partially substitute Ordinary Portland Cement (OPC) of 43 grade during the production of M25 grade of concrete mix design and to calculate the Flexural Strength in accordance with Indian Standards (IS). The outcome of this research analysis demonstrates that FA and BKD can be employed in the manufacturing of concrete with the objective of lowering both emissions of greenhouse gases and cement concrete production costs.
