Product Description Product DescriptionMetakaolin is a highly active mineral admixture, which is amorphous aluminum silicate formed by low-temperature calcination of ultrafine kaolin. It has high volcanic ash activity and is mainly used as a concrete admixture. It canalso be used to produce high-performance geopolymers.PropertiesSpec.Test results for referenceRefractoriness, oC≥1790 Bulk Density, g/cm3≥2.48 L.O.I (%)≤0.25 Mullite Phase (%)55-65 Mohs Hardness7-8 Fines in sands,%≤0.3 PH Value6-8 ChemicalsAl2O3,%46-4846.62SiO2,%50-5250.81Fe2O3.%≤1.20.89TiO2,%≤0.70.60CaO+MgO %≤0.50.38K2O+Na2O,%≤0.50.38Detailed Photos Metakaolin is a highly active artificial volcanic ash material that can react with Ca (OH) 2 (CH) and water to produce hydration products similar to cement. By utilizing this characteristic, when used as an admixture for cement, the CH reaction generated during the cement hydration process can improve certain properties of the cement.
