摘要： The invention relates to a superplasticizer for a cementitious composition, such as cement paste, mortar or concrete, characterized in that it is in the form of surface-modified particles constituted of mineral nanoparticles covered with a polymer coating formed predominantly of polyalkyl oxides. It enables a good fluidity to be maintained, without retardation of setting, and also gives the mortar or concrete composition anti-shrink properties.

摘要： The invention relates to an anti-shrink agent for a cementitious composition, such as cement paste, mortar or concrete, characterized in that it is in the form of surface-modified particles constituted of mineral nanoparticles covered with a polymer coating formed predominantly of polyalkyl oxides. It makes it possible to reduce the shrinkage by more than 65%, without retardation of setting, and also gives the mortar or concrete composition superplasticizing properties.
