Use of flexible sealing slurries for the aftertreatment of fresh concrete slabs

Abstract

The use of a slurry-type seal coating which is flexible after hardening, containing, as component a), a system having a proportion of hydraulic binder and, as component b), an elastifying plastic, for aftertreatment, over the whole area, of a concrete body having a residual moisture content >2 CM % is claimed. The claimed slurry-type seal coatings which contain, as component a), preferably a cement mortar and, as component b), a homo-, co- or terpolymer in the preferred form of a liquid polymer dispersion result in a higher strength and less shrinkage of the concrete body surface treated with them. The concrete bodies treated therewith are protected against seepage water, pressurised water and water splashes, in particular in areas exposed to wetness.
