GRC It is a new building decoration material and glass fiber reinforced concrete, which can be said to be an upgraded version of ordinary concrete building materials. There are specific data on the technical parameters of this new concrete building material. Today Baotou GRC Let's share the configuration method and parameters of waterproof concrete.
Waterproof concrete can be divided into four types according to the preparation method:
1. Improved graded waterproof concrete;
2. Ordinary waterproof concrete with more cement and ultra-fine powder filler;
3. Waterproof concrete mixed with additives;
4. Waterproof concrete with special cement.
The impermeability grade of waterproof concrete is determined according to the ratio of its large acting head to the small wall thickness of the building. Its construction requires even pouring, avoiding segregation, adequate vibration, strengthening wet curing, and strict control of water cement ratio. It is mainly used for projects and structures often affected by pressure water.
Waterproof concrete grade: P4, P6, P8, P10, P12.
GRC waterproof concrete refers to the concrete with good impermeability. The impermeability of concrete can be improved by changing aggregate gradation, reducing water consumption, and adding appropriate additives. The pouring quality shall be uniform and dense, and proper wet curing is required to prevent dry shrinkage cracks. Waterproof concrete is a kind of concrete with high impermeability and waterproof requirements.
