Anti-shrink additives

• Denka CSA #20 is an expansive additives which forms a stable crystalline structure within the cement matrix and gives a durable shrinkage reduction. The additive reduces shrinkage, heat of hydration and may increase strength. In Europe these additives are used mainly in shrinkage compensated mortars.


• Namex XA


• Namex XC


• Namex MOX

 Reactive pozzolanic fillers

• 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. 


• 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.

 Special binders

• Ecological binder


• Denka SC-1 is a very special accelerator for Portland cement which is supplied as an additive for finished products such as water stop and quick hardening mortar/concrete. It also supplies excellent hardening characteristics at low temperatures and very high early strength (depending on addition levels).
