| Abstract: | In this paper, with actual characteristics of Ningxia region, we selected lots of different labels, different strength cements for testing the actual strength, and calculated the range of cement＇s surplus coefficient Rc on the basis of ensuring the reliability of the strength of cement. Thereby it can make a guarantee for improving and enhancing the performance of concrete, and for educing material consumption. |
