高强混凝土结构的质量检验与验收

Qualities Checking and Acceptance of High Strength Concrete Structures

着重分析了《混凝土结构工程施工及验收规范》（ＧＢ５０２０４－９２）在高强混凝土质量检验和验收中存在的问题。采用匀质性指标（变异系数）分析，提出了高强混凝土质量检验和验收标准，很好地解决了规范中对平均强度要求过高或过低，而最小强度要求又偏低的突出矛盾。既简化了验收标准，又实现了验收标准随着混凝土强度等级提高而同步提高的目标。［

The problems existing in the qualities checking and acceptance of high strength concrete structure(HSCS)using Code for Construction and Acceptance of Concrete Structures(GB50204-92)have been studied. Depending on the analysis of index of uniformity (coefficient of variation), the standard of quality checking and acceptance for HSCS has been delivered.The contradiction which consists in the code,exorbitant or lacking average strength request- ing, and over-low minimum strength requesting, has been solved.The acceptance index is is simplified and the ac- ceptance standard would be raised with the concrete strength grade rising.
