  • Abstract:

The purpose of this study is to verify whether purchased commercially produced sandcrete blocks contribute to
collapsing of buildings in Lagos State. 20 sandcrete block industries were visited in Ikeja, in which six was randomly
selected for the study. Eighteen Sandcrete Blocks were randomly selected and purchased, three blocks from each
Block Industry including the soil samples and transported to the Department of Civil and Environmental Engineering
Geotechnical Laboratory FUTA where the following Tests were performed: Sieve, Silt Clay, and Organic Content
Analysis. The Compressive Strength Tests (CST) was conducted at Materials Testing Laboratory “the Ministry of
Works” Ondo State. The results showed that the soil aggregates used for the production of all the 18 blocks purchased
were found suitable. However, the compressive strength for all the blocks was found (0.34 N/mm2 and 0.377 N/mm2) to
be below the requirement (2.5 N/mm2) of Nigerian Industrial Standard (NIS) 87:2000. This indicates that
commercially produced sandcrete blocks may have contributed to the problem of building collapsing in Lagos State.
