Broad range of additives

Denka SC1 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).
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.
Censperse ^® Retarders are fine, free flowing powders to improve dispersion in dry mixed cementitious and gypsum systems. They are specially formulated set-retarding additives based on fruit acids and their salts. A special treatment helps to prevent agglomeration during storage; therefore sieving or milling is not required prior to blending with cement, aggregates etc.
