1. Function Henan Silica Density Manufacturer/News Information Silicea Density Price Silicea Density Construction Silica Density Dosage

Concrete silica 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. The frost resistance of concrete mixed with this product can reach 300 times. This product is suitable for concrete grade C20C60. The dosage accounts for 16% of the cement weight.

2. Densification principle

Concrete siliceous density agent uses sulfoaluminate minerals as Expanding dense and amorphous SiO 2 components, the cement products generated are mainly Afm and Aft, supplemented by water reduction and micro air entrainment to homogenize the internal structure of the concrete. It can be adapted to the construction of concrete moisture-proof, waterproof and anti-seepage projects for ultra-long structures of more than 150m without leaving any expansion joints.

3. All civil engineering projects (including construction, municipal administration, water conservancy, bridges, electricity, roads, airports , seaports) and other requirements that require non-shrinkage, crack-proof and dense anti-seepage and waterproof concrete, especially for cast-in-situ raft foundations of high-rise buildings, large water field projects, water diversion, water supply and drainage, and ground projects; at the same time, it is more suitable for cold areas Concrete projects that require resistance to freeze-thaw cycles have unique anti-freeze properties.

4. Technical effects:

Incorporating siliceous dense agent into concrete The concrete also implements the industry standard control value of JC474-92 “Concrete Expansion Agent”, and its dosage should change with the requirements of the impermeability design grade

2 Performance and Function

5. Performance and function

(1) Water impermeability: This product is used When configuring waterproof, impermeable and crack-proof 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 achieving the purpose of waterproofing.

(3) Water reduction rate: changes with the mixing amount. When 16% is mixed, the water can be reduced by about 18% in the mortar, and in the concrete Reduce water content by 20%.

(4) Strength: Adding this product can significantly increase the strength of concrete, reaching 70% in 3 days, and reaching 28-day strength in 7 days. It can be increased by about 20%.

(5) Save cement: 16% of this product can be used to replace cement, while the compressive strength and impermeability grade remain unchanged.

6. How to use:

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