Technical characteristics
1. The calcium sulfoaluminate expansion agent of this product has the effect of compensating concrete shrinkage to achieve anti-cracking. Concrete in the water for 14 days to limit the expansion rate is greater than 0.015%, and general waterproofing agent can only anti-seepage, can not crack.
2, this product is of high efficiency water reducing agent components with lower concrete water cement ratio, increase the concrete workability and compactness, further reduce concrete shrinkage, fill the concrete internal porosity, to improve the permeability grade and high compressive strength.
3, the product with the different season, the construction of composite retarder and other components, is to reduce the concrete hydration heat, reduce the temperature cracks, thus pouring mass concrete construction of concrete, summer, or mixing early strength agent or antifreeze can casting winter early strength antifreeze cracking of concrete.
4. Use this product to compensate for the construction of the reinforced concrete structure of more than 60m, without leaving the sprue, to expand the belt instead of the post-pouring belt, and continuously pour the concrete. It can be solved that the cleaning and chiseling of the pouring seam can bring trouble to the construction. After the solution, the sprue must be poured in 60 days, the long period of construction, the leakage of hidden dangers.
