Jiangsu siliceous density agent manufacturer, Zhejiang high-performance density agent, how much does it cost per ton, which Anhui silicon density density agent is the best?

1. Product introduction:

Add appropriate amount of concrete siliceous density agent into ordinary concrete, mix with water Hydrophobic gels and crystals are then generated, filling the capillary pores of the concrete, blocking the seepage channels, improving the density of the concrete, preventing or reducing shrinkage and cracking of the concrete, thereby improving the anti-seepage capability of the concrete structure. The concrete siliceous density agent makes the concrete slightly expand and dense, and has the functions of moisture-proof, waterproof, anti-seepage and anti-cracking. The anti-permeability grade of concrete mixed with this product can reach P20, and the frost resistance of concrete mixed with this product can reach 300 times. This product is suitable for concrete grades C20~C60. It can be adapted to the construction of concrete moisture-proof, waterproof and anti-seepage projects with long structures of more than 150m without leaving any expansion joints.

2. Scope of application:

Concrete siliceous density agent for silos and water storage Pools, water corridors, tunnels, dams, subways, underwater structures and other projects with high hydrostatic pressure requirements for cracking and seepage prevention, making it possible to achieve structural self-waterproofing, foundation engineering, layer engineering, repair engineering, post-casting Large-volume concrete projects with concrete, roads, bridges, airport pavements, parking lots and requiring expansion joints.

Civil engineering (including construction, municipal administration, water conservancy, bridges, electricity, roads, airports, seaports) and other requirements require non-shrinkage, anti-crack and dense anti-seepage and waterproof concrete , especially suitable for cast-in-place raft foundations of high-rise buildings, large water field projects, water diversion, water supply and drainage, and ground projects; at the same time, it has good frost resistance for concrete projects in cold areas that require resistance to freeze-thaw cycles.

3. Product performance:

1. Water impermeability: This product is used for configuration When waterproofing, impermeability and crack-proofing are used in dense concrete or mortar, the anti-permeability level can be increased by more than 3 times.

2. Compactness: Adding this product can reduce the porosity inside concrete by more than 50%, which can effectively reduce the number of capillary pores and macropores, thus To achieve the purpose of waterproofing.

3. Water reduction rate: changes with the mixing amount. When 5% is mixed, the water can be reduced by about 18% in the mortar and in the concrete. Reduce water content by 20%.

4. Strength: Significantly increase the strength of concrete in a short time, reaching 70% in 3 days, 28-day strength in 7 days, and 20% in 28 days. %about.

5. Save cement: 5% of this product can be used to replace cement, while the compressive strength and impermeability level remain unchanged.

4. Notes:

1. Use strictly according to the prescribed dosage, strictly control the water-cement ratio, and do not increase or decrease arbitrarily. When used in mortar, mix dry for 2 minutes first, then add water and stir;

2. When using this product, early maintenance must be strengthened to prevent concrete or mortar from losing water, which will affect cement hydration and slow down the later strength growth;

3. The product is used for mixing concrete or mortar with Portland cement, ordinary Portland cement, (GB1344-92) pozzolana cement and fly ash cement that comply with national standards (GB175-92). Other varieties should pass the test before they can be used. Use;

4. This product should be stored under dry conditions. If it becomes damp and agglomerates, it will deliquesce, but it will not lose its effectiveness and can still be used after drying and crushing.

5. How to use:

1. When the normal temperature is not lower than 0 degrees Celsius, This product can be incorporated directly into concrete or mortar. In order to achieve uniformity, the mixing time needs to be extended by 1 minute.

2. The dosage is 3-5% of the cement weight.
