浅谈水泥新标准使用后对混凝土配比的影响

通过水泥新标准的学习并结合有关参考资料，对新旧标准进行了对比，找出了区别点，应用新旧标准下水泥强度的加归关系、新旧配合比设计规程、哈尔滨建材院对新旧标准下的不同水泥做的不同强度等级的混凝土试验检测结果，探讨了水泥对混凝土配比中设计的影响，指出了新旧水泥标准中的水泥用量在混凝土配比中的用量差别。

Simple discussion on the effect on concrete ratio after the use of cement new standard

Through the study of new cement standard, combinin g reference data con cerned, new and old standard are contrasted, the difference is found. According to regression relations of cement strength under old and new standard, design re gulations of old and new match ratio, Ha'erbin Construction Material Institute g ive the detection result for concrete test of differential cement on various str ength grade under old and new standard. The effect of cement to the design of co ncrete ratio is discussed. At last, it is pointed out that the difference of qua ntity of cement in concrete match ratio under old and new standard.
