Metakaolin Cement Pozzolan

Product Snapshot

Product description
A high brightness (77/100 raw, >93/100 calcined) kaolin, with 50% of particles finer than 2 μm, low alkalis (K2O ~0.72%, Na2O ~0.10%), low iron content (~0.34% after magnetic separation, potentially lower with bacterial beneficiation), low titanium (~0.26%), high alumina (~35.1%), and a well ordered, crystalline structure.
Product uses
High Reactivity Metakaolin is a semi-calcined kaolin, used to enhance the performance characteristics of cement-based mortars, concretes, and related products. It contributes to increased strength, reduced permeability, greater durability, efflorescent control, and control degradation caused by Alkali Silica Reaction ("ASR").
