Waterproof concrete can be divided into four types according to the preparation method.

Waterproof concrete refers to concrete with good impermeability. Improve the impermeability of concrete by improving aggregate grading, reducing water consumption, and mixing appropriate admixtures. The quality of the casting is required to be evenly dense and requires proper wet curing to prevent dry shrinkage cracking. Waterproof concrete is a kind of concrete that has high impermeability and meets waterproof requirements.

Waterproof concrete can be divided into four types according to the preparation method:

1. Improve the grading method waterproof concrete;

2. Increase the amount of cement and ordinary waterproof concrete using ultrafine powder filler;

3. Waterproof concrete with admixture;

4. Waterproof concrete with special cement.

The waterproof concrete impermeability rating is determined by the ratio of its maximum acting head to the minimum wall thickness of the building. Its construction requires uniform pouring, avoiding segregation, sufficient vibration, enhanced moisture maintenance, and strict control of water-cement ratio. Mainly used in engineering and structures that are often subjected to pressurized water.

Waterproof concrete grade: P4, P6, P8, P10, P12 five levels
