ABSTRACT:
A lightweight aggregate for use in concrete mixes with Portland cement consists essentially of bottom ash produced as a by-product of burning pulverized coal in a dry-bottom furnace. The ash is sized to remove particles substantially exceeding 3/8 inch in diameter. It is substantially free of iron pyrites and sulfur trioxide to provide a lightweight aggregate which is inert, non-reactive, and meets the requirements for such aggregate as defined in ASTM specifications C-330, C-331 and C-332. Methods of producing this aggregate material are disclosed, including a method for recovering the same from the waste product ash in a power plant sluicing pond. Concrete mixes and products are disclosed in which such ash consists of the lightweight aggregate.
