UTILIZATION OF COAL ASHES FOR MANUFACTURING ECOLOGICALLY FRIENDLY BUILDING MATERIALS
The results of research and development related to the production of building materials containing high volumes of fly ash and bottom ash are presented. Coal ashes generated as a by-product of combusting coal in Israels power stations were considered as primary component in the industrial production of lightweight concrete. The coals are imported from different sources located in South Africa, Columbia and Indonesia. Although these ashes contain enhanced concentrations of natural radioactive materials, we developed a technology for producing concrete elements and structures which comply with national and international regulations setting limits on the activity concentrations of natural radionuclides in building products. In addition to the economic advantages of utilizing coal combustion products, which are usually regarded as problematic waste material, the large scale use of ashes (otherwise stored in piles and ponds near the power stations for long periods) has a potential for the reduction of environmental pollution in the vicinity of these power stations.
