Masonry mortars, precast concrete and masonry units using coal bottom ash as a partial replacement for conventional aggregates

Granular coal combustion products are problematic waste materials whose use as aggregates in concrete has been extensively studied. However, its integration into other non-structural and elements not so widely documented. Masonry mortars, precast masonry units with different ratios of bottom ash replacing conventional have With the incorporation workability, density strength decrease whereas porosity, weight loss drying shrinkage increase. low replacement slight effects. The an internal curing water reservoir is proposed most promising future line research.
