摘　　要：提高混凝土强度等级 ,以适应现代土木工程向大跨、重载、高耸发展的需要 .文中讨论提高混凝土强度等级对结构性能的影响 ,通过强度价格比的对比 ,分析提高混凝土强度可获得的技术经济效益 .同时 ,阐述如何采用强度较高的混凝土 。For promoting the strength of concrete so as to meet the need of developing civil engineering towards large-span and heavy load and high-rise, the authors discuss the effect of rising strength level of concrete on its structural behaviour; and analyse technical and economical benefit of rising strength level of concrete by comparing its strength-price ratio; and suggest to adopt concrete with higher strength so as to promote technical progress and sustainable development of building trade.

关 键 词：混凝土 强度等级 结构性能 强度价格比 技术经济效益 建筑材料 技术经济分析
