Scope of use of waterproofing agent Technical characteristics of waterproofing agent
According to the editor’s understanding, the cement waterproofing agent is a chemical additive that is added to the cement. When the cement solidifies and hardens, the volume expands, which plays the role of compensating shrinkage and tensioning steel bars to generate prestress and fully filling cement gaps. .
Application scope of waterproofing agent
Used in basements, bathrooms, reservoirs, purification pools, tunnels, roofs, floors, walls and other waterproofing projects.

Technical characteristics of waterproofing agent
1. The calcium sulfoaluminate expansion agent component of this product has the effect of compensating concrete shrinkage to resist cracking; curing concrete in water for 14 days limits the expansion rate to ≥ 0.015%, while general waterproofing agents can only resist penetration, not resistance to cracking. crack.
2. The high-efficiency water-reducing agent component of this product can reduce the concrete-water-binder ratio, increase the workability and compactness of the concrete, further reduce the shrinkage rate of the concrete, fill the internal porosity of the concrete, and improve the impermeability level and resistance to The effect of compressive strength.
3. This product varies with the construction season. The compound retarder and other components can reduce the hydration heat of concrete and reduce temperature difference cracks, thereby pouring large volumes of concrete, constructing concrete in summer, or adding early strength agent or anti-freeze The agent can be used to pour early-strength, frost-resistant and crack-resistant concrete in winter.
4. When using this product to compensate for shrinkage concrete to build a reinforced concrete structure of more than 60 meters, the post-pouring tape can be left out, and the post-pouring tape can be replaced by an expansion reinforcement tape, and the concrete can be poured continuously. It can solve the trouble caused by the cleaning and deburring of the post-pouring joints during construction; it also solves the disadvantages that the post-pouring joints must be poured after 60 days, the construction period is long, and there are many hidden dangers of leakage.
