admixtures for high strength concrete

Feature

 

1.low alkalinity.High-efficiency expansive agent has a very low alkanite content (R2O<0.3%) which is beneficial to avoid AAR in concrete.

2.Short stable stage of expansion.The stable stage is more than 14 days,thus the ultimate strength is not affected.

3.Low dosage and high expansion capacity.The normal dosage of high-efficiency CSA expansive agent is 6%-8% by the weight of ordinary cement ,which is lower compared with other expansive additives such as CEA(their dosage are about 10%-12%by the weight of cement )in the market.

Product Uses

UEA high-efficiency concrete expanding agent can be used for concrete projects and cement products requiring crack prevention, seepage prevention, jointing, filling.

Especially suitable for: 

     1. Underground buildings, such as the subway, underground parking lot, underground garage, tunnel mine, civil air defense works, underground walkways, airports, etc. 

2. Build a pool pool, sewage treatment tank, water tower, oil tank, etc. 

3. Self-waterproof rigid roofing mortar moisture-proof layer 

4. Prefabricated member frame structure joint anchored pipe joint structure post-casting backfill rock foundation grouting material. 

5. Cement products, cement pressure pipes, waterproof roof panels, etc. 

6. Highway pavement, bridge concrete surface, culvert.

Operation Step

 

1.When using this product, the same amount of gelled material of concrete replaced, recommended dosage is 8-10%, and the post-pouring strengthening band concrete afterpouring, need appropriate

 parameters.

 

2.This product configuration of the concrete can be used from structure waterproof technology, making building and waterproof in one, external waterproof can be canceled. Make the structure more

simple.

 

3.Concrete with this product can use the long seamless design and construction technology of 

reinforced concrete. Reduce the construction process, make construction simpler, greatly shorten the time limit for a project. Can also be used to deal with the common concrete cracks.
