The article looked at the quality and economics of compressive strength of sandcrete blocks produced in Ovia North East Local Government of Edo State, Nigeria. A total of 84 sandcrete blocks were batched from mix ratios of 1:6 to 1:18 and cured for 7 to 28 days. Results obtained showed that the minimum number of sandcrete blocks per bag was 15.36 at ratio 1:6 and maximum units of 41.70 at ratio 1:18. While material production costs ranged from 396.57 naira to 791.65 naira, corresponding to 41.70 and 15.36 blocks cast per bag, the corresponding compressive strengths ranged from 0.122N/mm2 to 1.404N/mm2 at 28-day curing period. The results indicated that these sandcrete blocks were below the recommended minimum strengths of 3.45N/mm2 and 2.45N/mm2 as per NIS 87:2007 for both load and non-load bearing cases. They also did not meet the standards set by National Building Code, 2006, of 1.75N/mm2.
