High-performance siliceous compacting agent is composed of a variety of materials such as waterproof, impermeable, crack-resistant, expansion, and dense components. When mixed with this product, ordinary concrete can be Changed to high-performance concrete, it is of excellent quality and meets the requirements of HPC. At the same time, it can be used as an HPC admixture.
Characteristics and dosage: This product is a powder material with a moisture content of <5%, and the dosage accounts for 3-5% of the cement weight.
Scope of use: dedicated to grain depots (impermeable, dense and waterproof)
Execution standards: this The product execution standard is JC474-2008 "Concrete Waterproofing Agent Standard".
Usage: Special silica density agent for grain depots. It has excellent waterproof, anti-permeability and shrinkage compensation properties. It does not burn, pollute, corrode or rust, and obtained the drinking water sanitation 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 specifications and regulations of concrete.
The grain depot concrete self-waterproofing project should meet the following requirements:
1. It should be strictly Carry out construction according to 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 assembly methods, slump, and timely maintenance should be adopted during construction. , to avoid shrinkage cracks and temperature cracks.
3. Adding 3% 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 500-meter-wide dense agent waterproof mortar should be made. (Do this three times). The dosage of post-cast concrete density agent is 3% of the cement dosage.
