Common Questions and Solutions

1. What is the recommended dosage of HPEG in concrete?

• Issue: Improper usage may lead to decreased concrete performance.

• Solution: The typical recommended dosage is between 0.2% to 1.0% of the cement weight. It is advisable to conduct small-scale tests in the laboratory to determine the optimal dosage.

2. How can the solubility of HPEG in water be improved?

• Issue: The solubility of HPEG in water can be affected by temperature and stirring speed.

• Solution: Ensure that HPEG is added at elevated temperatures and under appropriate stirring conditions. Using hot water or heated mixing equipment can enhance solubility.

3. What effect does HPEG have on the durability of concrete?

• Issue: Some users are concerned that HPEG may impact the durability of concrete.

• Solution: HPEG offers excellent flowability and crack resistance. When used appropriately, it can enhance the durability of concrete. Conduct long-term performance evaluations to ensure stability under various environmental conditions.

By using HPEG judiciously, the construction industry can significantly improve material performance, meeting the demands of modern building projects. If you have more questions or need technical support, please feel free to contact us!
