The cement industry standards drafted by the Cement Research Institute of the Chinese Academy of Building Materials, and other four cement industry standards have been reviewed and approved, and have recently been approved for release by the relevant authorities. The numbers and names are as follows: Mandatory Standard: JC453-92 Self-stressing cement physics Test Method JC454-92 Recommended Standard for Granulated and Granulated Ca-Containing Liquid Slag in Cement: JC/T452-93 Cement Quality Grading Principle JC/T455-92 Cement Raw Material Ball Performance Test Method The above standard was adopted in January 1993. 1 It is implemented from the day. In addition, for the smooth transition of old and new standards, the
