The range of strength for sandcrete blocks specified by N.I.S 74:1976 is between1.8N/mm 2 to 2.5N/mm 2 as the minimum strength. The blocks can cope with thermal and moisture conditions, and the problem of algae growth on the face of block work during construction is unlikely to affect the strength of the block (Edward, 1985). The compressive strength of hollow sandcrete block

Sandcrete - Wikipedia

Addition of coarse aggregates has been tried, since this is a cheap way to increase compressive strength, but since the cement content of sandcrete is small, so is the amount of water that is added to the sand/cement mix to cure it. Adding more solid materials makes the mix much less fluid, making it difficult to cast into blocks.
