It is optimized for use in fine and coarse mortar formulations rich in additives and fillers. Technical characteristics and advantages The white Portland cement Dyckerhoff Weiss CONTACT is produced using a special manufacturing process and complies with DIN EN 197-1 (internal and external monitoring) under the standard designation CEM I 42.5 R (dw). It is characterized by a flat grain range and a high degree of whiteness without a yellow or green cast (a = approx. -0.6; b = approx. 2.5). At the Ev. Church of the Redeemer, centuries-old natural stones were replaced with a special adhesive based on Dyckerhoff Weiss CONTACT and restored. The adhesive is tailored to the mineralogy of the natural stone and to rapid work progress. The applications show the good processing of adhesives based on Dyckerhoff Weiss CONTACT on the wall as well as on the floor. It is known that fine mortar formulations with high levels of plasticizers require a sufficient amount of dissolved sulfate ions. Therefore, in contrast to Dyckerhoff Weiss DECOR, a sulphate carrier mixture is dosed during grinding, the vast majority of which consists of quickly soluble hemihydrate and anhydrite. This means that Dyckerhoff Weiss CONTACT is particularly well tolerated by additives. It is particularly effective in connection with superplasticizers and air-entraining agents. This has a positive effect on the rheological properties in flowing masses. The consistently low water requirement leads to a low shrinkage behavior.
