Parameters
1. Waterproof mechanism
Concrete shrinkage-reducing, anti-cracking waterproof and compacting agent is a new generation of high-performance concrete and mortar waterproofing agent. When concrete and mortar are mixed with concrete shrinkage-reducing, anti-cracking, waterproofing and compacting agent, the pulling force of the hole solution on the hole wall is reduced by reducing the surface tension of the solution. In this way, the shrinkage formed by the loss of water from the capillary pores caused by drying is reduced. At the same time, the concrete shrinkage-reducing, anti-cracking, waterproofing and compacting agent can increase the viscosity of the pore water, enhance the adsorption of water molecules in the gel, and further reduce the final performance of the concrete. Shrinkage, prevent cracks and cracks in concrete, and improve the durability of concrete and mortar such as crack resistance, impermeability, frost resistance and corrosion resistance.
2. Function introduction
The application of shrinkage-reducing, anti-cracking, waterproof and compacting agent in concrete waterproof engineering can effectively improve the crack resistance, impermeability and durability of cement products, and fully improve the long-term strength.
1. This product has the functions of anti-cracking, compacting, and compensating for shrinkage.
2. Water resistance, oil resistance, alkali resistance, acid resistance, high temperature resistance, low temperature resistance, no aging.
3. Low chloride ion content, no corrosion or rust to steel bars;
4. Non-toxic, odorless, non-polluting, green and environmentally friendly.
3. Technical performance
1. Appearance: slightly yellow liquid.
2. Technical standard: JC474-2001.
3. Dosage: 2-3% (mass percentage of the cementitious material).
4. Impermeability: When this product is used to configure waterproof and impermeable concrete, it can increase the impermeability level by more than 3 times.
5. Compactness: Incorporating this product can reduce the porosity inside the concrete by more than 40%, which can effectively reduce the number of capillary pores and macropores.
4. Scope of application
1. Concrete shrinkage-reducing, anti-cracking, waterproof and compacting agent is especially suitable for high-performance concrete, high-strength concrete, silica fume concrete, and large-volume concrete to compensate shrinkage and drying shrinkage concrete to improve its impermeability and crack resistance.
2. Anti-cracking and waterproofing of concrete for tunnel lining, culvert frame structure, construction and underground waterproofing works.
3. Concrete caps, bridge piers, ballastless track cast-in-situ concrete ballast slabs, concrete bases and other concrete structures are impermeable and dense.
5. Matters needing attention
1. Dosage: Calculated according to the amount of cementitious materials, the dosage is 2-3%.
2. Mixing method: It can be directly added with mixing water to mix concrete or mortar for 2-3 minutes, or it can be diluted with 3-5 times of clean water and mixed with mixing water, concrete compound, sand and stone.
3. The composite blending effect of concrete shrinkage-reducing, anti-cracking, waterproofing and compacting agent and polycarboxylic acid-based high-performance water-reducing agent is better, and its shrinkage-reducing and anti-cracking effect will be increased by 20-30%.
4. Other technical requirements of concrete shrinkage-reducing, anti-cracking, waterproof and compacting agent concrete shall be implemented in accordance with the application technical specifications of ordinary waterproof and impermeable concrete. Wait.
5. Before use, it is advisable to do a trial mix test according to the design requirements, cement performance and environmental conditions to select the best technical effect.
6. If there is precipitation during storage, stir it before use.
6. Packaging and storage
1. This product should be stored in a cool place, and should be protected from sun damage during transportation. The shelf life is 180 days.
2. The concrete shrinkage-reducing, anti-cracking, waterproofing and compacting agent is a liquid product, packaged in 25kg or 220kg/piece plastic drums.
