Concrete siliceous density agent implementation standard: GB8076-2003. Function: 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. The frost resistance of concrete mixed with this product can reach 300 times. This product is suitable for concrete grades C20~C60. The dosage accounts for 16% of the cement weight. Densification principle: The concrete siliceous density agent uses sulfoaluminate minerals as the expanded dense and amorphous SiO2 components. The generated cement products 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.
Scope of use: All civil engineering projects (including construction, municipal administration, water conservancy, bridges, electric power, roads, airports, seaports) and other requirements that require non-shrinkage, anti-cracking and compactness Anti-seepage and waterproof concrete is 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 unique advantages for concrete projects in cold areas that require resistance to freeze-thaw cycles. Antifreeze properties. Performance and function, water impermeability: When this product is used to configure waterproof, seepage-proof and crack-proof dense concrete or mortar, it can increase the impermeability level by more than 3 times. Compactness: Incorporating this product can reduce the porosity inside concrete by more than 50%, which can effectively reduce the number of capillary pores and macropores, thereby achieving the purpose of waterproofing. Water reduction rate: It changes with the mixing amount. When 16% is mixed, the water can be reduced by about 18% in the mortar and 20% in the concrete. Strength: Adding this product can significantly increase the strength of concrete, reaching 70% in 3 days, 28-day strength in 7 days, and about 20% in 28 days. Save cement: 16% of this product can be used to replace cement, while the compressive strength and impermeability grade remain unchanged.
