1. Product Introduction
A small amount of shrinkage-reducing ingredients and organic surfactants are introduced into the penetrating crystal waterproofing agent to make it disperse more evenly. After being mixed into concrete, it reacts chemically with the compound products of cement, producing aluminum hydroxide, ferric hydroxide and other colloidal substances that block the capillary channels and gaps in the concrete, reduce the void ratio of concrete, improve its compactness, and also generate certain Expansive crystalline calcium sulfoaluminate hydrate, which not only has the function of filling and blocking capillary gaps, but also produces certain expansion properties, reduces or eliminates the volume shrinkage of concrete, and improves the crack resistance of concrete. The most prominent one is the crack resistance of concrete. Its characteristics are: automatic healing function of micro cracks of 0.3-1mm. Therefore, concrete mixed with a penetrating crystallized waterproofing agent has good physical properties such as waterproofing, antifreeze, anticorrosion, high strength, crack resistance, and durability, and truly achieves waterproofing and anticorrosion effects.
2. Recommended dosage
The recommended dosage is 4% of the weight of cement added to concrete, and 3% of mortar is appropriate.
3. Scope of application
This product is suitable for basements, large-volume civil air defense projects, roof waterproofing and impermeability, large-volume concrete anti-crack and impermeability, bridge concrete, tunnel impermeability concrete, tunnel anti-seepage Permeable concrete, sewage treatment plants, ports, wharf waterproof buildings, concrete with impermeable and anti-freezing requirements, etc.
IV. Construction Instructions and Precautions
1. The cement used should be ordinary Portland cement or slag Portland cement with a grade not less than 32.5. It is strictly prohibited to use expired or damp Clumped cement. For sand and stone, refer to the regulations for concrete.
2. Determine the amount of waterproofing agent according to the anti-permeability requirement level, mix it into the concrete, and extend the mechanical mixing for 2 minutes.
3. After the waterproof concrete is poured, it must be vibrated tightly and no vibration leakage, under-vibration or over-vibration is allowed.
4. After using cement penetrating crystallized waterproofing agent, no other additives can be added. If necessary, please contact our technical personnel.
5. Medium sand should be used as sand, the void ratio of the sand is ≤35%, and the mud content of the sand is <2%.
6. When the cement concrete enters final setting (watering and curing should begin about 10 hours after pouring), the curing period is the same as that of ordinary concrete.
7. Clean water should be used.
8. Maintain it according to the maintenance method of ordinary concrete. Cover the flat surface with wet straw mat or linen, etc., and keep it moist. The facade is maintained with mist water, and the water pressure should not be too high, at least three times a day. Continuous maintenance for 48 hours, several times a day when the weather is hot.
5. Packaging and Storage
This product is packed with plastic inside and braided outside. Each bag is 25kg. This product should be stored in a moisture-proof manner and has a shelf life of two years. </p
