PNF compound waterproofing agent
Product Presentation
PNF compound waterproofing agent is an admixture product composed of water reducing agent, plastic micro-expansion organic polymer and inorganic chemical components. This product can greatly improve the crack and impermeability of concrete, is an excellent concrete (mortar) composite multi-functional impermeability and waterproofing agent, can be applied to a variety of reinforced concrete construction technology, especially suitable for pumping process.
Main properties and dosage
1. The agent has the properties of micro-expansion, impermeability and crack prevention. After addition, swelling crystalline hydrate is generated due to hydration, which makes the mortar and concrete produce micro expansion and promotes the density of the structure. At the same time, in the case of constrained expansion, the appropriate compressive stress can be generated, which can offset the tensile stress caused by shrinkage and temperature difference of concrete, so as to effectively prevent the shrinkage and cracking of mortar and concrete.
2. The agent reduces the water-binder ratio of concrete by high efficiency water reduction, can significantly improve the workability of concrete, greatly improve the fluidity of concrete, prevent the concrete from bleeding and segregation, make the concrete appearance smooth and beautiful, and can significantly improve the strength of concrete at various ages.
3. It can improve concrete compactness, impermeability, freeze-thaw resistance, improve concrete durability, and prevent steel corrosion.
4. Good adaptability with different kinds of cement, especially suitable for Portland cement, ordinary Portland cement, slag Portland cement and other varieties.
Usage and precautions
1. Before the use of the product, the concrete test should be carried out according to the raw materials such as cement, sand and stone used in the project, combined with the on-site construction and design requirements, and the concrete mixing ratio and admixture amount should be determined.
2. Liquid products can be added with mixing water, powder products should be added when adding cement or after completion, and appropriately extend the mixing time.
3. This product has an obvious water reduction effect, should be used strictly according to the proportion of accurate weighing, especially in the rainy season construction must be based on sand, stone moisture content, timely adjustment
of water consumption, shall not add water at will.
