Abstract: The present disclosure discloses an organic silicon nano-precursor medium transmission inhibitor and its preparation method and use. The organic silicon nano-precursor medium transmission inhibitor is composed of an organic silicon and its derivatives, a catalyst, a dispersant, a stabilizer, a surfactant, and water. The organic silicon nano-precursor medium transmission inhibitor in-situ generates nanoparticles during a hydration process. The nanoparticles not only have a hydrophobic function, but also can effectively fill the pores of the concrete, which effectively solves a problem in which a hydrophobic material in a state of full water cannot reduce the diffusion of an erosive medium. The problems such as uneven dispersion and poor stability of nanoparticles added can be effectively solved by in-situ generating the nanoparticles, thereby effectively improving the ion corrosion resistance performance of the concrete.

Abstract: The present application discloses a polyhydroxy aromatic intermediate, preparation thereof and use thereof in a polycondensate water-reducer with branched side chains. The polycondensate water-reducer with branched side chains has a branched side chain structure which provides a stronger steric hindrance. The synergistic effect of the branched side chains and the rigid skeleton of the aromatic ring greatly improves the water-reducing ability. Especially under a condition of low water/cement ratio, the improvement in water-reducing ability is more obvious. The branched polyether side chain is more conducive to the formation of a thicker water film layer, which has an obvious viscosity reduction effect. The conformation of the branched polyether side chain is less affected by different ionic environments in the pore solution in cement, and thus has a stronger adaptability to various raw materials.
