Compressive Strength and Thermogravimetric Analysis of Metakaolin Blended Cement

Abstract

Cement concrete is the most extensively used construction materials across the world. The environmental unfriendliness attached to the production of cement which is one of the major constituents of concrete demands persistent attention and the wide use of pozzolanic material as partial replacement of cement in concrete looks to be a promising supplement for cement in concrete production.  Based on past research works, metakaolin was selected and its compressive strength and thermal resistance as well as other properties were determined. The replacement percentage of metakaolin employed was 5%, 10%, 15% and 20% by weight of cement with a mix ratio of cement to sand to granite of 1:2:4 cured at 7 days, 14 days, 28 days and 56 days . The output of this research work shows that with respect to compressive strength and thermal resistance, the metakaolin blended cement examined here is not suitable as supplementary materials for cement in construction industry.
