Abstract:
The present invention relates to cement-containing compositions which are characterized in that they have a proportion of organosilicon compounds of greater than 0.15% by weight, based on the proportion of cement, the organosilicon compounds being based on at least one organosilicon compound selected from the group consisting of the alkoxysilanes and at least one selected from the group consisting of the alkoxysiloxanes, to a process for the preparation thereof and to the use thereof.
