Expansion anticracking agent
Product features
1. Improve the crack resistance and waterproofing of concrete, add fiber to improve the crack resistance of concrete, add expansion components to participate in the hydration reaction to generate a large number of expansion of crystalline substances, filling the capillary channels, micro-cracks in the concrete, play a role in blocking the dense, improve the waterproofing performance of concrete, so that the concrete has the double advantages of compensating for the shrinkage and fiber crack-blocking.
2. Improve the compactness of concrete, the expansion component hydration products in the product, filling in the concrete, improve the compactness of concrete, increase durability.
3. Formulate compensatory shrinkage concrete, enhance the impermeability, can make the concrete structure to achieve the purpose of structural waterproofing, reduce the cost of external waterproofing materials and the cost of repeated maintenance later.
4. For extra-long concrete structure, it can realize continuous pouring, easy and fast construction, and save the cost of construction period.
5. The product is produced with low alkali raw materials.

Keywords:
classification:
Also known as high-performance fiber expansion anticracking agent, by adding fibers in the concrete to form a uniform chaotic support system, improve the crack resistance of concrete, the use of expansion components to participate in the hydration reaction to generate a large number of expansion of crystalline substances, filling in the internal capillary channels in the concrete, micro-cracks, to play a role in blocking the compactness of the concrete structure, and then improve the concrete's waterproof performance, so that the concrete has the double advantages of compensating for shrinkage and fiber crack-blocking, so as to achieve the purpose of self-waterproofing of the concrete structure. Concrete has the double advantages of compensating shrinkage and fiber crack-blocking, so as to achieve the purpose of self-waterproofing of concrete structure.
Scope ofapplication
Widely used in concrete structure waterproofing, engineering joint filling, continuous construction of long concrete structure, mass concrete field configuration of compensatory shrinkage concrete, prestressed concrete and other crack-resistant seepage requirements of the concrete project.
1. Underground buildings: such as subways, tunnels, underground parking lots, underground warehouses, tunnels, mines, civil defense projects, pits, piling and so on.
2. Waterproof structures: pools, swimming pools, water towers, storage tanks, large containers, grain silos, oil tanks, caves in the warehouse.
3. Plant, stadiums, large plazas, airport terminals, theaters, water conservancy and hydropower, offshore, ports, waterworks, power plants, reservoirs, dams, etc.
4. High-strength highway pavement, bridge concrete surface, culverts, etc.
