- 摘要:
- 本文着重讨论以525#水泥配制C50、C60高强混凝土的配合比设计特点。通过采用高效减水剂降低水灰比、适当增加水泥用量、降低砂率、改善集料级配等综合措施，不仅使混凝土强度、和易性等指标满足设计要求，同时兼顾了混凝土的经济性。
This paper mainly introduces the design features of C50 and C60 grade high strength concrete using 525# cement. By taking comprehensivenmeasures as to reduce water/cement ratio by using high performance water reducer, to moderately increase the amount of cement, to lower sand ratio and improve the grading of aggregates, not only the indexes of the strength of concrete, and the easiness in mixing the concrete meet design requirements, but also the economy of the concrete is considered.1996,3(3): 14-18 收稿日期：1996-1-30分类号：TU528参考文献：
