Four points of water seepage of waterproof construction structure

Дата релиза :2016-05-13

1, underground waterproof impermeability grade 0.6 MPa anti-seepage concrete basement floor big volume, uninterrupted construction requirements, cannot leave construction joints, casting of continuous success. Waterproof construction

In order to ensure construction quality and waterproof waterproof concrete, to prevent the cracks will take the following main technical measures of construction.

2, impermeability of concrete plan

Manufacturer concrete manufacturers of concrete early planning, lab assignments. And have professional engineers hot calculation with the best mixed concrete, cement consumption optimization to a minimum. Targeted preventive measures are put forward at the same time, in order to prevent concrete crack. As far as possible to reduce the number of cement hydration heat, using R without cement. Per cubic meter of the amount of cement in the concrete should be control in less than 300 kg, to reduce the hydration heat and prevent moisture from the crack.

3, use 3 doping technique, in order to prevent the crack

Weihe power generation class Ⅱ (1) mixing fly ash, replacing part of cement to reduce heat of cement, cement heat release rate, slow progress in the later strength of concrete. Waterproof construction

(2) the HEA shrinkage compensating concrete impermeability and using new technology to progress the density of concrete.

(3) mixed smoke retarder, reduce water consumption, slow hydration time, progress of concrete pumpability and workability.

4, the improvement of construction technology:

Based on building waterproof bare, the corner of the basement wall, and contraction, due to the influence of temperature, especially prone to stress, have gathered bag ever experience caused by walling, is the best measures to prevent such cracks increase fracture stress of the reinforcement quantity just around the corner to accept, have gathered to avoid cracks. The Tag is waterproof construction
