HCSA High Performance Concrete Expansive Agent (Clinker)
HCSA high-performance concrete expansion agent (clinker) is a high-tech product developed according to our factory's advanced process production line and unique science and technology under the personal guidance and support of relevant leaders and experts of China Building Materials Science Research Institute and China Concrete and Cement Products Association Waterproofing and Restoration Materials and Engineering Technology Branch. It is a science and technology cooperation project between our company and China Building Materials Research Institute, under the direct guidance of Professor Zhao Shunzeng of the National Building Materials Institute, its various performance indicators are better than the international industry level, and it is a high-quality product that fills the gaps in the industry at home and abroad.
The expansion performance is high, and the limited expansion in 7d water can reach 0.15~0.2, which is 4~8 times that of ordinary expansion agent.
2 expansion speed is appropriate, 3d water limit expansion can reach 70 ~ 80%,7d reached more than 85%.
3 Under the condition of absolute humidity, it can still maintain a large amount of expansion.
4 long-term performance is very stable.
