Summary Admixtures are included cement to improve the quality of cement. Mineral admixtures incorporate fly Ash FA, silica fume SF, ground granulated blast furnace slag GGBS, metakaolin MK, and rice husk ash RHA which have certain attributes through which they impact the properties of cement in an unexpected way. The detailed advantages of mineral admixtures are regularly

Science and Technology of Concrete Admixtures

Science and Technology of Concrete Admixtures

The effect of admixtures takes place at the paste level, and propagates through length scales to be felt at the macroscopic level of concrete. Thus studies on paste can provide correct relative properties at the concrete level for different admixed concrete, but cannot directly provide the absolute rheological properties of concrete.
