Pozzolanic reactivity and strength activity index of mortar containing palm oil clinker pretreated with hydrochloric acid

Palm oil clinker powder (POCP) is an agro waste material that is often overlooked due to its low pozzolanic reactivity and contaminated with impurities and organic carbon. Therefore this study was proposed to enhance the pozzolanic reactivity of palm oil clinker powder through a chemical pre-treatme...
