High-performance silicone compacting agent, with excellent waterproof and anti-permeability and shrinkage compensation properties, non-flammable, non-toxic, non-polluting, non-corrosive and non-rusting; it also has micro-expansion Function, it can effectively control cracks that are prone to dry shrinkage, temperature differences, etc. in large concrete pouring projects. 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 specifications and regulations of concrete. Waterproof concrete self-waterproofing projects in grain depots, food depots, water conservancy, bridges, electric power, airports, seaports, 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 methods, slump, and timely maintenance should be adopted during construction to avoid dry shrinkage cracks. and temperature cracks.
3. JH siliceous density agent mixed with 3% 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, steel plate waterstops should be added to construction joints, and an additional layer of densifying agent waterproof mortar should be made 500 wide (three times) . The dosage of post-cast concrete density agent is 3% of the cement dosage. </p
