1. Product introduction
High -performance silicon dense agent is composed of waterproof, penetration, crack resistance, expansion, dense components and other materials. High-performance concrete is of high quality and meets the requirements of HPC. At the same time, it can be used as an HPC admixture.
2. Properties and Dosage
This product is a powder material with a moisture content of <5%, and the dosing amount accounts for 3% of the cement weight.
3. Scope of use
Suitable for rigid waterproof concrete projects in construction, water conservancy, bridges, electric power, roads, airports, seaports and other projects. It is especially suitable for the construction of underground, roof and civil engineering projects with waterproof, moisture-proof and anti-seepage requirements, as well as the construction of water conservancy, seaports, electric power, roads and other engineering projects that require more than 500 freeze-thaw cycles.
IV. Implementation standards
The implementation standard for this product is JC474-2008 "Concrete Waterproofing Agent Standard".
V. How to use
In order to meet the user’s requirements for structural self-waterproofing, large concrete pouring projects such as underground box foundations, raft foundations, water plants, sewage treatment plants and swimming pools are prone to occur. To solve the problems of cracks such as dry shrinkage and temperature difference, we carefully launch Jade brand JH high-performance silica compacting agent, which can meet the purpose of compensating for shrinkage with a 14-day water expansion rate of 1.5×10-4.
JH high-performance silica The compacting agent has excellent waterproof, anti-permeability and shrinkage compensation properties, is non-flammable, non-toxic, non-polluting, non-corrosive and non-rusting, and has obtained the drinking water hygiene license from the Anhui Provincial Department of Health. The dosage is 3% of the cement dosage, the mechanical mixing time should be greater than 3 minutes, and the water consumption, construction management and maintenance methods should be strictly implemented in accordance with the relevant concrete specifications and regulations.
Concrete self-waterproofing projects such as raft or box-shaped underground foundations, basement structures, water plants, sewage treatment plants, culverts, tunnels, etc. should meet the following requirements:
1. Construction should be carried out in strict accordance with the design requirements. It is appropriate to use Portland cement or ordinary Portland cement larger than 325#. It is prohibited to use pozzolanic cement and slag cement, and it should comply with international (GB175-85) regulations. The coarse aggregate is medium and coarse sand, and the mud content should be Less than 2%; the mud content of the aggregate should be less than 1%.
2. Reducing water consumption is a prerequisite for reducing capillary pores and increasing density. Measures such as strict control of mass distribution, slump, and timely maintenance should be adopted during construction to avoid shrinkage cracks and temperature cracks.
3. Adding 3% JH siliceous density agent to cement is an effective method to improve waterproofing and impermeability and compensate for shrinkage.
4. Lead plates and rubber waterstops should be added to deformation joints, and steel plate waterstops should be added to construction joints and an additional layer of densifying agent waterproof mortar of 500 meters wide should be made (three times). The dosage of post-cast concrete density agent is 3% of the cement dosage.
6. Packaging, transportation and storage
This product is 30kg/bag. During transportation and storage, it should be protected from rain and sun to avoid moisture and clumping. </p
