Performance of concrete protectant

I. Concrete protectant can play the role of concrete protective layer, protect the internal steel corrosion, extend the life of the structure.

Two, the concrete protective agent needs to be in full contact with the concrete in order to achieve a good waterproof effect, so the surface of the concrete structure should be cleaned up first, such as slurry, dust. Cracks in the first repair with quick-setting cement and other good;

Third, it is a low-density waterproofing material of water agent, directly in the concrete grass-roots level can be evenly sprayed two times, without additional maintenance and so on. Construction cost is low, construction progress is fast;

four, penetration depth can reach about 3 centimeters. The impermeability grade reaches S11 or above.

V. Good acid and alkali resistance, corrosion resistance. Can resist the effect of temperature changes on concrete. Can resist the penetration of chloride ions on the concrete damage. Can enhance the compressive strength of the surface of the concrete structure;

Sixth, the concrete protective agent requires a stable effect. After construction, basically the same life as the concrete structure;

VII, can be constructed in the wet concrete work surface, but there can not be open water. Can be constructed in the back of the water surface;

eight, because it is a deep penetration crystalline waterproofing materials, so there will be no aging, lap is not tight, delamination sliding and other traditional problems exist;

nine, you can play a good role in the protection of concrete, reinforcing steel;

ten, completely environmentally friendly and non-toxic, can be done for swimming pools, sewage lagoons, waterworks, and other interior walls.

Xi, because it is a deep penetration crystalline waterproofing material, so it is not the surface sealing of water beads, but into hydrophilic.　Water-based penetrating concrete protector is a reactive inorganic silica compounds, its waterproofing mechanism is a chemical reaction with the free alkali and other active ingredients in the concrete, generating stable dendritic crystalline gel, effectively blocking the concrete internal microscopic cracks and capillary voids, so that the concrete structure has a long-lasting waterproofing function and better compactness and compressive strength. The depth of penetration is up to 20-30mm, and it can also effectively stop the erosion and destruction of concrete by acid and alkali substances, oil stains, seaweeds and salt.

Improve the durability of concrete: stop the water as a carrier of acid, alkali, salt, CO2, SO3 and other media on the erosion of concrete, extend the service life of concrete;

Bridges, building fa?ade protection: effectively prevent the water, de-icing salts, freezing and thawing on the corrosion and destruction of steel reinforcement; corrosion prevention function with a low rate of diffusion of chlorine ions; excellent depth of penetration, good breathable "Excellent penetration depth, good breathability;

Colorless and transparent, does not change the color and appearance of the grass-roots level;

Simple construction: do not level protective layer, do not sprinkle water maintenance, etc.;
