摘要： The invention relates to copolymers based on phosphorous-containing monomers (A) and on macromonomers (B), to methods for the production thereof and to their use as additives for inorganic binding agent suspensions based on cement, lime, gypsum and anhydrite. The corresponding polymeric additives have, as flow agents, excellent water-reducing properties and hold the flowability of the concrete over a relatively long period of time (60 to 90 min.) to an almost unchanged level without having delayed action. In addition, the corresponding polymeric additives improve the processing and setting processes of the building materials produced with these additives by making possible earlier and higher resistances to pressure.

摘要： The invention relates to the use of polymer microparticles comprising a cavity in hydraulically binding building material mixtures, between 1 and 100 vol. % of the cavity of said microparticles being filled with water. In this way, a significant concrete resistance to changes in frost and dew states is achieved, said microparticles providing improved protection of the concrete against the effects of changes in frost and dew states, with a diameter of between 0.1 and 1 µ and doses that are smaller than those in prior art by between 1 and 2 orders of magnitude. Furthermore, the pressure resistance of the correspondingly hardened concrete is significantly improved, which was not the case before. The invention also relates to compositions containing polymer microparticles and hydraulically binding building material mixtures, and hardened building material mixtures produced using such compositions.
