Jiangsu siliceous density agent manufacturer high-performance anti-crack and anti-permeability cement manufacturer direct sales

1. Product introduction

High-performance silica density agent is composed of waterproof, impermeable, anti-cracking, swelling, compacting components and other materials. When mixed with this product, ordinary silica compacting agent can be The concrete is changed into high-performance concrete, which is of excellent 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 less than 5%, and the dosage accounts for 3% of the weight of cement.

3. Scope of use

Special for grain depots

4. Implementation standards

The implementation standard for this product is JC474-2008 “Concrete Waterproofing” Agent Standards”.

5. How to use

Special silica density agent for grain depots. It has excellent waterproofing, impermeability and shrinkage compensation properties. It is non-flammable, non-toxic, non-polluting, non-corrosive, No rust, and 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 regulations of concrete.

The grain depot concrete self-waterproofing project 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 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 500-meter-wide dense agent waterproof mortar 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. It should be protected from rain and sun during transportation and storage to avoid moisture and caking. </p
