The invention relates to the use of polymeric microparticles, whose shells contain additional monomers for electrostatically and/or sterically repelling the microparticles, in hydraulically setting building material mixtures, for improving their freeze resistance and/or freeze-thaw resistance.
La présente invention concerne des microparticules polymériques dont la coque contient des monomères supplémentaires destinés à la répulsion électrostatique et/ou stérique des microparticules, notamment l'utilisation de ces particules dans des mélanges de matériaux de construction à prise hydraulique pour améliorer leur résistance au gel ou au gel-dégel.
