ZS-FS Permeable Crystalline Waterproof Material
Product introduction
Cement-based permeable crystalline waterproof coating is a powder waterproof material made of special Portland cement, refined quartz sand, etc. as the base material and infiltrated with various active substances. The product has catalytic activity. After encountering water, the active substance in the material penetrates into the concrete with water as a carrier, and can continuously produce chemical reactions to produce water-insoluble needle-like crystals with the cement hydration products. Fills the capillary channels and microscopic gaps inside the concrete, thereby improving the compactness and waterproofness of the concrete.
Based on this crystallization principle, even if the concrete structure is partially damaged and leaks, it will repair itself by crystallization after encountering water (0.4mm crack). No need to do other waterproof layer repairs, it has the characteristics and performance of waterproof, impermeability and self-repair, and has a strong anti-seepage pressure ability, the waterproof layer and the concrete surface form a complete system, which will not be separated and will not be hollowed out. Phenomenon. Because of its breathable and impermeable characteristics, it can be cured simultaneously with the concrete structure. Therefore, it has the effects of multiple self-healing repairs, improving impermeability and waterproofing for a long time.
Applicability
It is used for waterproof construction of tunnels, underground diaphragm walls, cable ducts, underground culverts, basements of industrial and civil buildings, bathrooms, reservoirs, pools, swimming pools, elevator shafts, etc.
Notes:
1. Pay attention to the weather forecast before construction, and prohibit construction in rainy days or under low temperature environmental conditions.
2. Store in a cool and dry place above 5℃, avoid long-term exposure to the air, and strictly prohibit contact with water. The shelf life is 24 months.
3. Should first deal with leakage points and gaps, and then carry out large-scale construction. For special waterproof parts, the dosage should be appropriately increased and strengthened.
4. This product is non-dangerous and meets the transportation requirements to avoid rain and damage to the packaging.
Subsurface treatment
The construction base surface should be firm, clean, smooth, free of clear water, dust, oil, shedding and other debris; fully wet the concrete base surface (no clear water) before construction, which can speed up the special characteristics of the product. The chemical reaction between the active substance and the substance in the concrete improves the adhesion between the waterproof material and the base surface.
Construction method
Brush construction: material/water ratio is 5:2;
Spraying construction: material/water ratio is 2:1;
Add water in proportions and stir until batter. After 10 minutes, stir again until the powder is completely free of particles. According to different base surfaces and construction site conditions, the ratio of material to water can be slightly adjusted, which generally does not affect the waterproof effect. The construction dosage is 0.8-1.8kg/m², and the coating thickness is 1.0±0.2mm. After the first layer is dry and solid, the second brushing is carried out. The coating direction of the second layer should be perpendicular to the direction of the first layer. In order to prevent cracks and chalking on the surface of the coating, the waterproof coating should be kept moist. After the construction, the coating should be sprayed and maintained with spray water. It needs to be sprayed 2-4 times a day. frequency. It must be protected from rain and frost within two days after construction. For applications under long-term water immersion, the waterproof layer should be cured for at least 14 days before water storage.
Internal admixture: In key projects, internal admixture can be adopted, and the admixture amount is 1.0-3.0% of the amount of cement in the concrete.
