Abstract

See full text

A comb polymer is used to increase the flow rate and / or reduce the viscosity of a mineral binder composition, wherein the comb polymer has a backbone comprising acid groups and sidechains attached to the backbone, and wherein a number average molecular weight of all side chains is 120-1,000 g / mol is, and a molar ratio of the acid groups to the side chains in the range of 0.5 - 2.
