Abstract
Abstract: In this study the influence of partial relief of Ordinary Portland cement by Metakaolin and Rice Husk Ash were delved. In the last decade the use of supplementary bonding accoutrements has come an integral part of high strength and high performance concrete blend design. Rice hull ash is a by- product material attained from the controlled combustion of rice hull which consists of non-crystalline silicon dioxidewith high specific face area and high pozzolanic reactivity. Metakaolin helps to reduce the quantum of calcium hydroxide, therefore performing in stronger and durable concrete. OPC was replaced with these mineral admixtures at 2, 4, 6 and 8% by weight. 0% relief served as the control. Compressive Strength test was carried out on hardened 150 mm concrete cells after at 7 and 28 days curing in water. Compression strength test confirms its felicity as a partial relief mineral amalgamation.
