Abstract
The study explored metakaolin as alternative material to cement. It compares the properties of
Ordinary Portland Cement (OPC) concrete and binary concrete containing metakaolin as partial
replacement of OPC. Two set of concrete samples; one with 10% Metakaolin (MK) replacing OPC
by weight, and the other without MK (100% OPC) as control, were produced. The samples were
tested for compressive and tensile strengths at 7, 14, 28 and 90 days. The result revealed that the
slump of the binary concrete was 26% lower than the control. However, the compressive and
tensile strengths of binary concrete were higher than those of control by 10.8% and 11.9% at
28days, and by 21.6% and 34.5% at 90 days, respectively. Therefore, the MK produced from
Kankara Kaolin can be used as Pozzolan to improve the strengths of concrete.
