ABSTRACT: Concrete is a versatile construction material. Its most critical property is the compressive strength. The basic constituents of concrete are a cementitious material and aggregates. The most common type of cementitious material used for concrete in Nigeria is Ordinary Portland Cement. The strength of concrete and the rates at which it is developed depends largely on the type and quality of cement. The rates of strength development of concrete using some selected brands of cement in the Nigerian market were investigated by means of laboratory tests. It was established that, the concrete develops an average of 26% of the 28 day strength in 1 day and 85% in 21 days. It is concluded that concrete develop strength rapidly at early age compared to later ages. Most cement brands in Nigeria develop strength at satisfactory rates.
