SYW-14 expansion agent
1. Incorporating this product can greatly improve the anti-cracking and anti-seepage performance of concrete, and it also has the function of compensating for shrinkage.
2. The restricted expansion rate of the concrete mixed with this product is 0.02~0.04%, and the prestress of 0.2~0.7Mpa can be established in the concrete.
3. The alkali content is small, which can reduce the damage of the expansion agent to the concrete alkali aggregate reaction when mixed into the concrete.
4. This product is non-toxic, non-flammable, non-corrosive, and has no corrosion on steel bars.
1. The mixing amount of this product is 6-8% of the cement amount.
2. Mixing generally adopts the internal mixing method, adding this product together with cement, sand, stone and water and mixing well. The mixing time is extended by 30～60s.
