Abstract: High carbon fly ash is a waste material, which has not been adequately utilised. This research explored the possibility of utilising the material in conjunction with soil for wall construction of low cost housing. An optimum quantity of high carbon fly ash was added to the shell and a substantial quantity to the core of a shelled compressed earth block. Appropriate laboratory tests were conducted to investigate the behaviour and properties of the masonry unit. Results of Tests showed adequate compressive strength of 4.2 N/mm2 and a stable condition of masonry unit upon exposure to moisture. This is a part of the expanded construction opportunities of an on-going research in compressed earth technology.
