Abstract

This paper evaluates the satisfaction of the minimum compressive strength requirement of laterized earth moist concrete for grade C20 of BS 8110 (1997) for use in reinforced concrete works, which is 20 N/mm2. Compressive strength test and water absorption tests were conducted with laterite partially replacing fine aggregate. Batching was by weight, mix ratio of 1:2:4 (cement: laterite/sand: granite) was used with a water/cement ratio of 0.3. sized concrete cubes were cast and cured for 56 days, then weighed and crushed. The result shows that the compressive strength of the earth moist concrete (EMC) at 0%, 10% and 20% laterite replacement for 28days respectively are , and . The compressive strength of the EMC 0%, 10% and 20% laterite replacement for 56 days respectively are , and . These indicate that increase in the compressive strength of all the EMC specimen is directly proportional to the increase in curing age but increase in the laterite replacement reduces the strength.
