Abstract

A technology for comprehensive utilization of high volumes of coal ashes for production of lightweight concrete was developed at The Research Institute of The College of Judea and Samaria, Ariel, Israel. The technology is based on the combined use of bottom ash and fly ash in lightweight concrete, which enables the advantages of each kind of the ashes to be realized. The features of the suggested technology were confirmed under laboratory and field studies. The obtained binary concrete (with respect to coal ashes) is a beneficial material for production of masonry units. The current paper describes the results of testing the effect of concrete proportions on properties of the binary lightweight concrete and of combined use of coal ashes with waste fines from stone quarries as additive for ternary lightweight concrete. The use of these materials both controls the strength of the lightweight concrete containing highly porous bottom ash and lowers the concentrations of radionuclides226Ra,232Th and4°K in the lightweight concrete.
