PROPERTIES OF FAL-G HOLLOW MASONRY BLOCKS

Niranjan PS, Radhakrishna

Abstract: FaL-G is the product name derived from a cementitious mixture composed of Fly ash (Fa), Lime (L) and Gypsum (G). It is a low-cost and environmental-friendly material. FaL-G in certain proportions, as a building material is an outcome of innovation. It gains strength like any other hydraulic cement in the presence of water. It is water resistant too. 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 of FaL-G masonry hollow blocks were determined for different parameters. The experimental results reveal that the FaL-G hollow blocks are suitable to be used for the construction of masonry structures.

Keywords: fly ash, lime, gypsum, quarry dust, sand, mortar, hollow blocks.
