摘要
混凝土强度是混凝土结构安全性的重要指标。当前,混凝土强度检验评定实践存在混凝土试件的代表性和真实性受质疑、检测报告存在诱导性错误、将较小强度值的试件剔除后再评定检验批混凝土强度、检测推定无效试件代表的结构实体强度及将回弹法作为验收标准等问题。以某地工程建设实际为例,从实证方面分析并讨论了上述问题,最后从建设工程质量政府监管角度提出相应的建议。
Concrete strength is an important indicator of the safety of concrete structures. At present,evaluation of concrete compressive strength in practice exists that the authenticity and representativeness of the concrete specimen are questioned,and inductive error exist In the test report,and strength of the inspection batch is evaluated after the specimen of the smaller strength is removed,and the structural entity strength represented by the invalid specimen is detected and the rebound method has become an acceptance criterion. These problems are analyzed and discussed from empirical analysis with taking the actual construction of some areas as an example. Finally,the suggestion is provided from the perspective of government supervision in construction project quality.
