Micro-filler, Microsit®

Microsit® is micro-fly ash produced by separation. It is used as a certified addition for cement-related high-performance construction materials. In addition to its filling effect in the micro field, Microsit® also improves the rheological properties of lime, mortar and concrete. Microsit® is especially suitable for the manufacture of construction materials which are subjected to chemical and physico-mechanical load, as well as for the production of highly free-flowing and self-compacting building materials, and extra-fine bonding agents for injection materials. Other areas of application include casting and filling compounds, injection and repair mortar. Due to its extreme fineness and its spherical grain form as well as its excellent processing properties, Microsit® is also being used as a filler in coatings and plastics.
