摘要
The self plating concrete cement composition comprises a rheological modifier mixture, which is characterized in that it comprises a combination of at least one first agent, which mainly increases the shear threshold of concrete selected from natural polysaccharide ether. A hydroxyalkylated ether, Hydroxyethylcellulose or hydroxypropyl compound is hydrophobically modified by impregnation with a hydrophobic side graft and at least one second viscous agent, which mainly improves the viscosity of concrete in the fluid state selected from the hydrophobic hydroxyalkylcellulose.2. It has a solution viscosity of less than 50 PASC% by weight and a recovery degree of about 500-4500 for poly (vinyl oxide);In order to limit or prevent the dynamic separation of particles in concrete when using the composition, the presence of fillers in concrete, especially in self plating concrete, can be made without reducing the expansion performance, sieve stability and compression performance. The dynamic separation of the concrete from the filled concrete, especially the concrete associated with water / cement.
