MetaKaolin for Cement Mortar and Concrete 

Lightweight Filler And Reactive Admixture: High Reactive Metakaolin   MKA 11 is metakaolin calcined from high quality Kaolin. It can react with calcium hydroxide which is the outgrowth of portland cement in the course of hydrating and product a new colloidal material, which is also called pozzolanic reactivity. As to the high effective pozzolanic reactivity, MKA11 can enhance the performance of concrete and mortar obviously.   The functions of MKA 11: - significant increase in compressive and flexural strength, especially early strength - reduce and eliminate the phenomenon of efflorescence - improve the resistance of permeability - enhance concrete durability - reduce and eliminate the reaction of alkali and silica (ASR) - enhance the resistance of chemical attack - good color adaptability as white color   The recommended dosage of MKA 11 is 5~15% of the weight of cement or cemen…
