Experimental Study of Strength & Durability of Concrete by Partial Replacement of Cement with Metakaolin

To achieve sustainability in construction world number of substitutions materials are used. Metakaolin is widely used green pozzolanas. Metakaolin is calcinied clay (koalite). It is obtained from raw material i.e. Kaolin Clay (very fine, white). There is very little emission of carbon dioxide whiles the production of Metakaolin as compared to cement hence it is called as green pozzolanas. Today many researches are ongoing for the replacement of Portland cement, using many waste materials like fly ash and GGBS. Like Fly ash and GGBS a Metakaolin can also use as a binder with the partial replacement of cement which take some part of reaction at the time of hydration reaction. Cement replacement by glass powder in the range 5% to 25% with an interval of 5% is to be study.Material was tested for its compressive strength and workability concrete prepared with partial replacement of Metakaolin showing significant improvement in their properties.
