Low concrete rebound strength / low concrete surface strength What is the good way to reduce the concrete rebound strength / low concrete surface strength
First of all, the two points are emphasized: concrete strength, hardness and material immersion times (unit usage) and material contact reaction time. All construction techniques are similar, but they are adjusted according to the basic conditions. The basal condition determines Absorption (unit usage).
Zhengxiang Z2 Concrete Hardener (Enhanced) is a high-tech product developed by Tianjin Zhengxiang Technology Co., Ltd., which is used to solve the problems of low strength and low rebound strength of cast molding concrete. The rebound value can generally be increased by 5%-30% (about 2-10 rebound values), and the carbonization depth is reduced.
Concrete reinforcement range:
The concrete that has been poured into the concrete has a low strength due to curing, mix ratio, use of an admixture, freezing, and the like. Including: ground, walls, columns, bridges, tunnels, etc.
Zhengxiang Z2 concrete hardener use method:
1. Please stir before using this product.
2, the concrete surface is kept dry, such as high concrete surface density needs to be polished
3. In order to improve the rebound value of concrete, brush the Z2 material on the surface of the structure by roller coating, and repeat the painting repeatedly, with a single interval of 10-30 minutes to maintain the saturated wet state, so that the material fully infiltrates the interior of the concrete structure; In the following 2 days, the Z2 material is continuously applied according to the above method, and the structural strength is continuously increased.
4. The treated concrete will take effect in 1-2 days, and the best effect will be achieved in about 5 days.
