ASA - Anti shrinkage agent

ASA – controlled volumetric changes

Special additive ASA chemically modifies the course of hydration reaction and compensates for the concrete mixture shrinkage during setting and hardening. Using this additive, increased volume stability = lower tendency to crack generation is ensured. When used in floor materials (filling, self-levelling screed), the generation of cracks is reduced, as far as material is concerned. When used in filling materials (mortar, grouts), it also ensures filling and fixation of the areas concerned. In the long-term perspective, i.e. in the first few months - the use of the additive improves the shrinkage curve.
