Experimental analysis of changes in cement mortar containing oil palm boiler clinker waste at elevated temperatures in different cooling conditions

Changes in cement-based materials containing waste after exposure to elevated temperatures are an important aspect that should be studied in developing sustainable construction materials. Modified cement-based materials obtained using the industrial waste present robust engineering properties can le...
