These blocks were made of cement 1.25 parts, lime 0.5 part, sand and gravel 6 parts, and were tamped from damp mixture. It is probably safe to assume that the minimum crushing strength of well-made blocks, 1 to 5, is 1,000 pounds per square inch at 1 month and 2,000 pounds at 1 year.
(PDF) compressive strength of sandcrete blocks | Orjinta,
The range of strength for sandcrete blocks specified by N.I.S 74:1976 is between1.8N/mm2 to 2.5N/mm2 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).
