Silica dense agent – concrete silica dense agent – waterproof silica dense agent

Concrete siliceous density agent hotline: 18055268997

1. Product introduction

Silica density agent

is composed of various materials such as waterproof, impermeable, anti-cracking, expansion, and dense components. It is compounded. The addition of this product can change ordinary concrete into high-performance concrete. It is of high quality and meets the requirements of HPC. At the same time, it can be used as an HPC admixture.

2. Characteristics and dosage

Concrete siliceous density agent is a powder material containing water. The rate is less than 5%, and the dosage accounts for 3% of the cement weight.

3. Scope of use

Silica compacting agents are used in construction, water conservancy, bridges, Rigid waterproof concrete projects for 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.

4. Implementation Standards

The implementation standards for siliceous dense agents are JC474-2008 "Concrete" Waterproofing Agent Standards".

5. Usage

In order to meet the user's requirements for structural self-waterproofing, for underground Large-scale concrete pouring projects such as box foundations, raft foundations, water plants, sewage treatment plants and swimming pools are prone to cracks such as shrinkage and temperature differences. We carefully launch Jade Brand JH high-performance silica dense agent to meet the needs The expansion rate in water for 14 days is 1.5×10-4 for the purpose of compensating for shrinkage.

Silica dense agent has excellent waterproofing, impermeability and shrinkage compensation functions. Non-combustible, non-toxic, non-polluting, non-corrosive, non-corrosive, 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 specifications and delineations of concrete.

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 is It 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 dry shrinkage cracks and temperature cracks.

3. JH siliceous density agent mixed with 3% cement is an effective way 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.

6. Packaging, transportation and storage

The packaging of concrete siliceous density agent is 30kg/ Bags should be protected from rain and sun during transportation and storage to avoid moisture and clumping.
