What precautions should I pay attention to when using it?

Polycarboxylic acid water reducing agent is a commonly used concrete additive, which can effectively reduce the amount of cement in concrete, improve the fluidity of concrete and reduce the shrinkage of concrete. However, the use of polycarboxylic acid water reducing agent also needs to pay attention to some problems. The following is a detailed introduction to how to use the polycarboxylic acid water reducing agent. Firstly, the use of polycarboxylic acid water reducing agent should follow the following principles: 

1. Choose suitable varieties of polycarboxylic acid water reducing agent, according to the nature and requirements of concrete, choose suitable varieties of polycarboxylic acid water reducing agent.

2. Use the polycarboxylic acid water reducing agent in strict accordance with the instructions for use, and do not overuse or use improperly.

3. Consider the use of polycarboxylic acid water reducing agent in the design of concrete proportion, and reasonably control the water-cement ratio of concrete and the dosage of polycarboxylic acid water reducing agent.
   The use of polycarboxylic acid water reducing agent is as follows:

4. Before mixing the concrete, add the polycarboxylic acid water reducing agent into the water of the concrete and mix well.

5. In the process of concrete mixing, polycarboxylic acid water reducing agent should be added at the right time according to the need to ensure the fluidity and working performance of concrete.

6. In the process of concrete construction, pay attention to the slump and fluidity of concrete, and adjust the dosage of polycarboxylic acid water reducing agent in time.
   The precautions of the polycarboxylic acid water reducing agent are as follows:

7. The dosage of polycarboxylic acid water reducing agent should be reasonably controlled according to the nature and requirements of concrete, and should not be used in excess.

8. The use of polycarboxylic acid water reducing agent should follow the instructions for use, and should not be used improperly or exceed the use period.

9. The storage polycarboxylic acid water reducing agent should pay attention to moisture-proof, sun-proof, frost-proof, and avoid mixing with other chemicals. In conclusion, polycarboxylic acid water reducing agent is an important concrete additive, which can effectively improve the performance and working performance of concrete. However, when using polycarboxylic acid water reducing agent, we also need to pay attention to some problems to ensure the quality of concrete and the safety of the project.
   Polycarboxylic acid high-performance powder water reducing agent 26C produced by Tongrun is a powder water reducing agent made by adding liquid water reducing agent to various additives such as polymerisation blocking agent, anti-binding agent, etc., and then adding stabilising agent after pre-screening through spray drying tower and retaining the water reducing agent’s water reduction, slump preservation, durability, and various excellent properties that can be adapted to a wide range of construction environments.
