EARLY SETTING for early covering
Whenever screed is laid, the question is asked: ‘When it will be set and ready for the next layer?’ According to German standard DIN 18560, this occurs when the residual concrete moisture (CM) falls below 2%, or below 1.8% in the case of heated screeds. With normal screeds and poor environmental conditions, this can actually take a number of weeks or even months. But time is money! With our screed systems, you can achieve early setting and covering. How? Screed dries thanks to two phenomena. One is hydration, during which water is chemically bound by the reaction with cement. The other involves the evaporation of excess water added in order to achieve the necessary application consistency. MC’s Powerscreed actively accelerates hydration while at the same time reducing the volume of surplus water. This means that the water-cement ratio is also positively influenced, leading to increased early and final strength values.
