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
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)
