What are the usage and dosage of liquid polycarboxylate superplasticizer, and what should we pay attention to?

Our liquid PCE(Polycarboxylate superplasticizer) series is suitable for many kinds of concrete products. According to different customer requirements, we have different models of PCE. Dosage range: Generally, the dosage is 0.5-2% of the weight of the cementitious material The dosage and storage conditions of PCE should be attention; the instructions for use should be followed

Our liquid PCE(Polycarboxylate superplasticizer) series is suitable for precast and cast-in-place concrete, reinforced concrete and prestressed concrete in high-speed railways, passenger dedicated lines, industrial and civil buildings, roads, bridges, ports, airports and other engineering construction.

According to different customer requirements, we have KPS-102 high water reduction PCE, KPS-103 collapse-preserving PCE, KPS-104 hybrid PCE, and KPS-106 slow-release PCE. We will make recommendations based on different application areas and the materials of customers.

Dosage range: Under normal circumstances, the dosage is 0.5-2% of the weight of the cementitious material when converted to 20% solid content, and the recommended dosage is 1.0%. The specific dosage needs to be changed according to the customer's materials and environment.

Finally, the precautions for polycarboxylate water reducer are as follows:

1. The dosage of polycarboxylate water reducer and superplasticizer is precisely controlled according to the concrete strength grade, construction requirements, and specific conditions of use.

2. The use of polycarboxylate water reducer should follow the instructions for use and should not be improperly used or exceed the service life.

3. When storing polycarboxylate water reducer, attention should be paid to moisture-proof, sun-proof, and frost-proof, and avoid mixing with other chemicals.

In short, polycarboxylate water reducer is an important concrete additive, which can effectively improve the performance and working performance of concrete. However, when using polycarboxylate water reducer, we also need to pay attention to some issues to ensure the quality of concrete and the safety of the project.
