OPC was replaced with these mineral admixtures at 5%, 10% and 15% by weight. 0% replacement served as the control. Compressive Strength test was carried out on hardened 150mm concrete cubes after at 1, 3, 7, 28, 45 & 56 days curing in water. Compression strength test confirms its suitability as a partial replacement mineral admixture.en-USStaff Publication - SoETStaff Publication - CEArticle
