Mineral fillers and pozzolans

Microsit^® is a fly ash classified to very fine particle sizes (10µ or 20µ). The fineness of the spherical particle guarantees a higher pozzolanic reactivity and improves the rheology of mortars and concrete. Microsit is approved under DIN 1045-2 for concretes and can partially replace cement.
EFA Füller^® is a pure fly ash. Through its spherical form a better flow and a water reduction is obtained. It is classified as a concrete additive according to DIN EN 450.
Metaver^® is a specially calcined kaolin that reacts with the free Portlandite to form added CSH phases (calcium-silicate-hydrate; cement binder). This makes the cement matrix denser and gives unique properties, e.g. chlorine resistance, reduced efflorescence.
PowerPozz ^® is a white, amorphous, alumino-silicate which reacts aggressively with calcium hydroxide to form compounds with cementitious value. The product makes the cement matrix denser and gives unique properties, e.g. good thixotrophy, reduced efflorescence.
