INFLUENCE OF AGGREGATE REPLACEMENT UPON THE CHARACTERISTIC STRENGTH OF CONCRETE CONTAINING MALAYSIAN LATERITE

Abstract

Strength development of concrete indicates the significance of curing temperature in the activation of hydration process. This study addresses the effect of aggregate replacement upon the characteristic strength of concrete 
containing Malaysian laterite aggregate (MLA). In this study, MLA was utilized to partially replace of coarse aggregate at 0%, 10%, 20%, 30%, 40% and 50% (by weight of coarse aggregate) and cured at three different curing regime (water curing, natural curing and air curing) until the testing day. The results show that up to 30% in concrete mix, showed that the concrete is able to attain the targeted strength which is 30 MPa.
