The compressive strength of sandcrete blocks is affected by the mix proportion, quality of material used in making them, size, shape, and the mode of manufacture (i.e. hand or machine mould). Physical conditions such as method and days of curing, duration of time, temperature etc will also contribute to the strength of the block (Dhir, 1980).

Results from the compressive strength tests showed that all the sandcrete blocks were substandard, as they fall below the minimum permissible compressive strength valve recommended by Nigeria Industrial Standard (NIS-87). From the results, the mean compressive strength ranged from 0.653 Nmm-2 to 1.203 Nmm-2. In addition, the results of the sieve analysis
