[ We claim:] [1.] A mineral binder system, especially for the construction industry, comprising a mineral binder and a supplementing agent in dry powder form, wherein the supplementing agent comprises a finely divided, swellable layer silicate and an additive, wherein the percentage of swellable layer silicate in the supplementing agent is more than about 60 wt. % and the swelling volume of the layer silicate is about 5-50 ml, when measured in terms of a suspension of 2 g of the layer silicate in 100 ml water and wherein the percentage of the supplementing agent in the mineral binder system is about 0.01-5.0 wt. %, in terms of the total solids content of the mineral binder system.
