Abstract

FaL-G is the product name given to a cementitious mixture composed of Fly ash (Fa), Lime (L) and Gypsum (G). It is low-cost and environmental-friendly material very useful even in rural housing industry. FaL-G in certain proportions, as a building material is an outcome of innovation to promote large-scale utilization of fly ash. It gains strength like any other hydraulic cement in the presence of water and it is water resistant when hardened. This paper addresses the technology of making FaL-G mortar compressed hollow blocks with low-calcium (Class F) dry fly ash as the base material. The FaL-G masonry hollow blocks were prepared without the use of conventional cement. Quarry dust and sand were used as fine aggregates as sustainable materials. The properties and compressive strength of FaL-G masonry hollow blocks were tested with different parameters. The experimental results reveal that the FaL-G hollow blocks are suitable to be used for the construction of masonry structures.
