Silicone anti-cracking compacting agent is easily soluble in water. After stirring, it is evenly distributed in the concrete and chemically reacts with cement hydration precipitates to form crystals and gels. It reduces the volume shrinkage of concrete and improves the crack resistance of concrete, especially the crack resistance of large-volume concrete. At the same time, during the growth process, the gel fills and blocks the pores in the cement stone, cutting off the connection of capillary pipes, making the porosity inside the concrete smaller, and improving the compactness and impermeability.
Product Features
1. Improve the crack resistance, impermeability and Durability, fully improving long-term strength.
2. It has the functions of crack resistance, density and shrinkage compensation.
3. Water-resistant, oil-resistant, alkali-resistant, acid-resistant, high-temperature-resistant, low-temperature-resistant, and non-aging.
4. No anti-corrosion and no rust for steel bars
5. Harmless, odorless, No pollution, green and environmentally friendly.
Scope of application:
1. Bridges, tunnels, overpasses, industrial plants, residential areas and civil use Key projects such as buildings, water tanks, water towers, roads, and airport buildings
2. Crack resistance of concrete used in tunnel linings, culvert frame structures, buildings, and underground waterproofing projects Waterproof
3. Concrete caps, bridge piers, slag-free track cast-in-place concrete track slabs, concrete bases and other projects
4. Waterproofing projects for roofs, floors, walls, kitchens, bathrooms, basements, etc. of industrial and civil buildings
5. Various pools , swimming pools, underground warehouses, civil air defense projects, subways, tunnels and other building moisture-proof and waterproof projects.
Technical performance
1. Technical standards: JC474-2008 GB23439-2009;
1. p>
2. Low shrinkage: the mixture will not shrink and settle, and the anti-cracking agent can absorb internal stress and improve crack resistance;
3. Crack resistance: The anti-crack density agent is easily dispersed in the mortar to form a three-dimensional spatial structure, which effectively improves the phenomenon of poor hardening and cracking caused by excessive drying of concrete and insufficient moisture;
4. Impermeability: When used to configure waterproof and impermeable concrete, the impermeability grade can be increased to S8-18 or above;
5. Operability: Because the anti-crack densification agent has a slump-preserving effect, it reduces the frictional resistance of pumped concrete; anti-crack densification can increase the plasticity of concrete, improve construction operability, and improve work efficiency;
6. Compactness: It can reduce the porosity inside concrete by more than 40% and effectively reduce the number of capillary pores and macropores; dosage: 4-10%;
Construction Precautions
1. Add directly to the mortar or concrete mixer, the mixing time is Normal stirring is extended for 30-60 seconds, counting 2 and a half minutes or 3minutes. If manual stirring is required, the mixture must be evenly mixed;
2. The concrete mix design is the same as that of ordinary concrete, but the cement dosage should not be less than 300kg/m3;
3. Choose fresh but not expired waalate cement or ordinary waalate cement. The cement has good activity and stability. The cement label is generally P.032.5 or P.042.5;</p
