A Review on Concrete Performance Towards Incorporation of Recycled Material - Coal

Abstract

The use of coal additives in concrete has acquired popularity in recent years due to their potential performance-enhancing benefits. The ability to mitigate aggressive ion penetration, a chemical reaction that can cause concrete to degrade and potentially fail, is one of their most significant advantages. This literature review concentrates on the effect of coal additives, specifically coal fly ash and bottom ash, on the performance of concrete, with an emphasis on its strength and resistance to chemical attack. The review investigates several studies that investigate the properties of coal additive concrete, including its compressive strength, durability, and chemical penetration resistance. The findings indicate that the addition of coal to concrete can improve its properties, resulting in enhanced performance and durability. However, certain limitations must be considered, such as variations in the properties of coal residue based on the source and combustion process, for which geochemical analysis can provide insight into the causes. To fully comprehend the potential of coal additives in concrete and to address any limitations associated with their use, additional research is required.
