  • To dissolve polyvinyl alcohol, the material should be added to room temperature water under stirring. Disperse evenly and then heat up to accelerate the dissolution, which can prevent caking and affect the dissolution speed. The polyvinyl alcohol aqueous solution (5%) is very sensitive to borax and boric acid, which is easy to cause gelation. When the borax reaches 1% of the solution mass, irreversible gelation will occur.

  • Air-entraining agent, also known as air-entraining agent, is a hydrophobic surfactant. It is dissolved in water and added to the concrete mixture, which can generate a large number of tiny air bubbles during the stirring process. Air-entraining agents can improve the workability, water retention and cohesion of concrete mixtures, and improve the fluidity of concrete. In the mixing process of concrete mixtures, a large number of uniformly distributed, closed and stable micro-bubble admixtures are introduced.
