Features: Chapter 4 and Chapter 6 of this standard are mandatory, while the rest are recommended. This standard replaces JC714-1996 《Rapid-hardening Sulfoaluminate Cement》 and JC435-1996 《Rapid-hardening Ferraluminate Cement》。 Compared to JC714-1996 and JC435-1996, the main changes are as follows:
---
---
- JC714 and JC435 are merged into one standard;
- Cement strength grade is changed to strength grade;
- Strength grade indicators are determined;
- Cement strength test methods are replaced by GB/T17671-1999 《Test Method for Strength of Cement Mortar》 instead of GB/T1771-1999 《Test Method for Strength of Cement Sand》, and the water-cement ratio and cement mortar flow range for strength tests in this standard are determined.
