The need for nuturing of low cost building materials industry in developing countries has long been recognized throughout the world. costs of building materials. Therefore, construction of low cost housing has become more difficult. The objective of the research was to utilize minimal cost materials, such as coal combustion by-products (fly ash, bottom ash, etc.), for production of masonry blocks for low cost housing construction. The research was done in two phases. The first phase was designed to identify mixtures of fly ash and binder which would yield blocks of sufficient strength to withstand handling, transfer and long term exposure. The final phase was designed to determine the response of acceptable fly ash block mixtures, from Phase I study, to continued soaking in fresh water.
