Application scope:
Mainly used for repairing concrete roads and factory cement floors, treating cement pavement peeling, sanding, freeze-thaw, salt erosion, exposed stones, honeycombs, and rough surfaces. This product is widely used for rapid repair of concrete in bridges, docks, water conservancy, high-speed rail, nuclear power, large-scale municipal engineering, and other fields.

Product Features:
1. High intensity.
2. Rapid strength growth: Standard maintenance state: The strength of the repair material can reach over 20Mpa after one day, and it can be opened to traffic in 2-4 hours under normal weather conditions.
3. Waterproof and anti-seepage performance superior to concrete: After pouring cracks with early strength repair materials, the micro expansion function of this product can fill and expand the slurry inside the cracks, providing sufficient waterproof and anti-seepage effects.

To prevent metal corrosion, it is required that the coating has an insulating effect, which can block water, oxygen, and other substances from penetrating through the coating from the external environment and reaching the metal interface. Inorganic pigments such as glass flakes and aluminum powder added to coatings can enhance the isolation effect of the coating. Corrosion inhibition and passivation effects of coatings: Anti corrosion coatings usually contain chemical anti rust pigments with corrosion inhibition and passivation effects, which interact with metal surfaces to produce new surfaces such as passivation and phosphating films. The electrode potential of these thin films is positive compared to the original metal, which partially or completely avoids the possibility of the metal surface becoming an anode.
4. The amount of water added is 16% to 18% of the weight of the repair material, which is 8-9 kilograms of water per bag of material
Construction method:
1. Before use, it is necessary to clean the loose materials and dust on the surface of the repaired concrete, and only when there is no visible water can construction be carried out.
2. When mixing, the repair material should be mixed evenly according to the water consumption provided in the instructions (i.e. 8-9 kilograms of water per bag) before pouring for construction. If the pouring area and volume are too large, a small amount of fine stones or large sand can be added to reduce concentrated exothermic reactions. Pour the mixed slurry into the area that needs to be repaired, compact and smooth it, and cover it with plastic film and water it for curing in a timely manner after the repair slurry has finally set. In winter, it is necessary to cover it with cotton felt for insulation protection.

Some are dug out from underwater and pumped in the form of mineral mud. According to the content of SiO2 and clay minerals in the ore, it can be divided into the following three categories: diatomaceous earth (SiO285%), clayey diatomaceous earth (SiO25%~85%), diatomaceous earth clay (SiO25%). Diatomaceous earth is a biogenic siliceous sedimentary rock mainly composed of ancient diatom remains. Its chemical composition is mainly SiO2, containing small amounts of l2OFe2OCaO, MgO, K2O, Na2O, P2O5 and organic matter. SiO2 typically accounts for over 8% and can reach up to 94%. The iron oxide content of diatomaceous earth is generally 1-1.5%, and the aluminum oxide content is 3-6%.
3. Road opening hours: Depending on the customer's design intensity and construction season, the fast opening hours are 2-8 hours.
Attention: This product is packaged in 50kg/bag (kraft paper composite bag)
Storage conditions: Dry environment for 12 months without affecting use

Waterproof materials should meet the following requirements: they can significantly reduce the water absorption of the stone; Maintain the permeability of water vapor to a certain extent; Deep penetration; Fully resistant; UV resistance; No health hazards to people. Organic silicon waterproof materials can fully meet the above requirements. Unlike molded coatings such as wax and resin, organic silicon waterproof agents do not block or seal the pores on the surface of the stone, but only form a thin film on the pore wall of the stone, and the entire pore is still unobstructed. In this way, on the one hand, the protective layer formed on the surface of the stone has a lower surface tension, which prevents water from spreading and wetting the stone. On the other hand, liquid water cannot penetrate into the stone through the capillary pores that form the protective layer, because as polar water, it can no longer interact with non-polar hydrophobic layers, despite being in contact with each other.
