Coal bottom ash

This paper aims to study the effect of coal bottom ash (CBA) as a fine aggregate substitution at high levels on the mechanical properties and microstructure characteristics of concrete. CBA that sourced from a local coal-fired power plant in Vietnam was used to replace the natural sand (NS) in the concrete mixtures at different levels of 0, 30, 50, 70, and 100%.

This study addresses these issues by using recycled lightweight aggregates (RLWA) from waste polystyrene plastic as an alternative for coal bottom ash in the production of lightweight composites (LWC) incorporating ternary binder materials of cement, fly ash, and ground granulated blast-furnace slag.
