Abstract
A comb polymer is used for increasing the flow rate and/or reducing the viscosity of a mineral binder composition, where the comb polymer has a main chain including acid groups and there are pendent chains linked to the main chain, and where the average number-average molar mass of all of the pendent chains is from 120 to 1000 g/mol and the molar ratio of the acid groups to the side chains is in the range from 0.5 to 2.
