Abstract:
The metakaolin is a pozzolona material which is extensively used in concrete as a cementitious material. It is obtained by calcination of kaolinite. Usage of metakaolin enhances the properties of the concrete. The properties of metakaolin can be controlled which is not a property of other mineral admixtures. It acts a filler material and increases the hydration of cement. Creep and shrinkage are the long term defects in concrete which can be controlled by addition of metakaolin. Metakaolin at a dosages of 0%, 5%, 10%, 20%, and 30% were added to cement concrete. In almost all the cases metakaolin has given the good performance, it reduced the autogenous and drying shrinkage and also reduced both the basic creep and drying creep
