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 ~ 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.

L'invention concerne l'utilisation de microparticules polymères, présentant un espace vide dans des mélanges de matériaux de construction assemblés avec de l'eau, 1 à 100% en volume de l'espace vide de ces microparticules étant rempli par de l'eau. De cette manière, une résistance au béton est améliorée contre les changements de gel et d'humidité, ces microparticules offrant également une protection améliorée du béton contre les actions du gel et de l'humidité, et se présentant sous un diamètre compris entre 0,1 et 1 ? et des dosages, qui sont inférieures de 1 à 2 fois l'ordre de grandeur présent dans la technique antérieure. En outre, la résistance à la pression du béton ainsi obtenu est considérablement améliorée, ce qui n'était pas le cas avant. L'invention concerne, de plus, des compositions contenant des microparticules polymères et des mélanges de matériaux assemblés par de l'eau, ainsi que des mélanges de matériaux durcis et obtenus lors de l'utilisation desdites compositions.
