Nanyang xingang paint co., LTD tells you how to prevent leakage of oil paint?

1. Underground waterproof and anti-seepage grade is 0.6mpa impermeable concrete basement floor with large volume and uninterrupted construction requirements, no construction joints can be left, and the pouring is successful continuously. Waterproof construction

Oily coating to guarantee construction quality and waterproof waterproof concrete, in order to prevent the following primary technical measures to be adopted in the construction of cracks.

2. Anti-seepage concrete collaboration ratio scheme

Concrete manufacturers advance concrete cooperation ratio scheme, experimental operations. And professional engineers calculate the best mix of concrete, cement consumption optimized to the minimum limit. Propose targeted prevention measures together to prevent concrete cracks. In order to reduce the hydration heat of cement, try to use R without cement. The amount of cement per cubic metre of concrete should be controlled at less than 300kg to reduce hydration heat and prevent moisture cracking.

3. Use doping technology to prevent cracks

When mixed with fly ash, it replaces part of cement to reduce hot cement, slow thermal release rate of cement, and late strength of progressive concrete. Waterproof construction

HEA compensation shortens the use of new technology to make concrete impermeable and dense.

Slurry mixed drainage retardant, water consumption reduction, time of slow hydration, pumpability and ease of moving concrete.

4. Technical improvement:

According to the construction, the corner of the outer wall of the basement is shortened. Due to the influence of temperature, especially the simple stress rendezvous, the wall cracks are formed. The best way to prevent this kind of cracks is to add the stress rendezvous that can be accepted within a few days.
