What is silica density agent? Siliceous compacting agent is a high-performance green new admixture made of a variety of inorganic raw materials rich in cement active and reinforcing components through scientific and technical processes. So let’s learn a lot about the product information of silica density agent through this article.
1. Performance and function
Impermeability: This product is used to configure waterproof and resistant When dense concrete or mortar is used to prevent seepage and cracking, the anti-seepage grade can be increased by more than 3 times.
Denseness: Adding 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 waterproofing the goal of.
Water reduction rate: changes with the mixing amount. When 16% is mixed, the water can be reduced by about 18% in the mortar and the water in the concrete. 20%.
Strength: Adding this product can significantly increase the strength of concrete, reaching 70% in 3 days, reaching 28-day strength in 7 days, and 20% in 28 days. % about.
Save cement: 16% of this product can be used instead of cement, while the compressive strength and impermeability grade remain unchanged.
Usage: When the normal temperature is not lower than 0 ℃, this product can be directly mixed into concrete or mortar. To achieve uniformity, the mixing time needs to be extended by 1 minute.

2. Scope of application
Crack resistance and waterproofing of concrete used in tunnel linings, culvert frame structures, buildings and underground waterproofing projects;
Concrete bearings Platforms, bridge piers, slag-free track cast-in-place concrete track slabs, concrete bases and other projects;
Roofs, floors, walls, kitchens, bathrooms of industrial and civil buildings , basement and other waterproofing projects;
Moisture-proof and waterproofing projects for various pools, swimming pools, underground warehouses, civil air defense projects, subways, tunnels and other buildings;
Key projects such as railway bridges, tunnels, industrial plants, community civil buildings, water storage tanks, water towers, roads, and airport buildings.
3. Precautions
Add directly into the mortar or concrete mixer, the mixing time is longer than normal The mixing is extended for 30 to 60 seconds;
The concrete mix ratio design is the same as that of ordinary concrete, but the cement dosage should not be less than 300kg/m3;
Select fresh but not expired wafer salt or ordinary Portland cement, which has good cement activity and stability. The cement grade is generally P.0 32.5 or P.0 42.5;
The sand and quartz grades are good, the mud content is low and comply with relevant regulations;
The concrete must be vibrated Dense, no sliding vibration, no strong vibration, concrete and mortar should be compacted, fine stone concrete should be used in the house, small plate should be vibrated and then compacted;
Mortar or concrete should be covered with wet straw bags in time to strengthen moist curing. The general curing time is not less than 7 to 14 days. H-307 concrete curing agent can also be used for curing.
