Strength and Durability Properties of Concrete with Partial Replacement of Cement with Metakoalin and Marble Dust - A Review

Ordinary Portland cement (OPC) is conventionally used as the primary binder to produce concrete. The amount of the Co2 released during the manufacture of OPC due to the calcinations of limestone and combustion of fossil fuel is in the order of one ton for every ton of OPC produced. Attempts are made to reduce the use of Portland cement in concrete are receiving much attention due to environment-related. In the present study Metakaolin and marble duat used as a partial replacement for cement. Metakaolin is a calcinied clay and It is a Dehydroxylated form of the clay mineral Kaolinite. Stone having higher percentage of Kaolinite are known as china clay or kaolin was traditionally used in the manufacture of porcelain ceramic material. The particle size of Metakaolin is smaller than cement particles and where as Marble dust is obtained from cutting and manufacturing industries of marble. In India near about 3500 metric tons of marble dust slurry per day is generated. So, Marble dust is very easily available with very less cost. Kaolinite is also called as green pozzolana because it emits less co2. In this project an experimental work is been performed to determine mechanical properties of concrete with metakaoline and marble dust is replaced with cement with the known percentages such as 0%,10%,11%,12%,13%,14%,15% for the grade of M20.
