• Description/Remarks <!-- business info -->High-reactivity metakaolin (HRM) has high pozzolanic reactivity which makes it ideal for use in Portland cement blends and cement-based plasters, mortars and concrete. The particle size is similar to the particle size of cement, which promotes an intimate and reactive mix. It has also been successfully used and tested as a pozzolanic ingredient or activator in Geopolymer formulations. The pozzolanic reactivity is defined through the metakaolin’s ability to react with free lime as the by-product of Portland cement hydration. Addition of K40 METAKAOLIN to cement can improve curing rate, strength, durability, density and resistance to chemical attack. It also reduces alkali-silica reactions and efflorescence in the finished product. The white colour gives an attractive light finish.<!-- /business info -->
