Abstract

FaL-G is the product name derived from a cementitio us mixture composed of Fly ash (Fa), Lime (L) and Gypsum (G). It is a low-cost and environmental-friendly material. FaL-G in certa in proportions, as a building material is an outcom e of innovation. It gains strength like any other hydraulic cement in the pre sence of water. It is water resistant too. This pap er addresses the technology of making FaL-G mortar compressed hollow blocks with l ow-calcium (Class F) dry fly ash as the base materi al. The FaL-G masonry hollow blocks were prepared without the use of conv entional cement. Quarry dust and sand were used as fine aggregates as sustainable materials. The properties of FaL-G maso nry hollow blocks were determined for different par ameters. The experimental results reveal that the FaL-G hollow blocks are sui table to be used for the construction of masonry st ructures.
