Product introduction:
A concrete improvement admixture that can improve the compactness and impermeability of concrete gel, reduce early shrinkage of concrete, and effectively control concrete cracks.
High-density siliceous density agent is a concrete shrinkage-reducing, crack-resistant and waterproof density agent. It is a new green additive with low alkali, low dosage and high performance. This product can fill the capillary pores of concrete, block water seepage channels, improve the density of concrete, prevent or reduce shrinkage and cracking of concrete, and improve the anti-seepage ability of concrete structures. Suitable for concrete grades from C20 to C60. It is suitable for the construction of concrete moisture-proof, waterproof and anti-seepage projects in ultra-long structures without leaving any expansion joints.
Scope of application:
High-density siliceous compacting agent can be used for projects with high anti-cracking and anti-seepage requirements and a certain hydrostatic pressure, foundation projects, layer projects, repair projects, and post-casting It is suitable for large-volume concrete projects such as concrete, roads, bridges, airport pavements and requiring expansion joints to achieve structural self-waterproofing.
All civil engineering projects (construction, municipal administration, water conservancy, bridges, electricity, roads, airports, seaports) require non-shrinking, crack-proof and dense anti-seepage and waterproof concrete, especially for cast-in-place rafts of high-rise buildings It is more suitable for foundations, large water field projects, water diversion, water supply and drainage, and ground projects; at the same time, it has unique anti-freeze properties for concrete projects in cold areas that require resistance to freeze-thaw cycles.
Performance:
★ Water impermeability:
This product can improve the impermeability level when used to configure waterproof, impermeable and crack-proof dense concrete or mortar. More than 3 times.
★ 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, thereby achieving the purpose of waterproofing .
★ Water reduction rate:
It changes with the mixing amount. When 5% is added, the water can be reduced by about 18% in the mortar and 20% in the concrete.
★ Strength:
Significantly improve the strength of concrete, reaching 70% in 3 days, reaching 28-day strength in 7 days, and increasing by about 20% in 28 days.
★ Save cement: 5% of this product can be used instead of cement, while the compressive strength and impermeability level remain unchanged.
