预拌混凝土应用《混凝土强度检验评定标准》问题的讨论

Discussion on applying "Inspection and assessment standard for concrete strength" to pre-mixed concrete

《混凝土强度检验评定标准》GBJ107-87颁布实施后,预拌混凝土经过了快速的发展,在进行工程质量验收时,应如何科学评定其强度是否符合标准和设计的要求尚有待展开讨论,并完善标准。本文讨论了预拌混凝土在执行《混凝土强度检验评定标准》应用统计法评定强度时遇到的问题,以及可能遇到的验收风险。

After the issue of＂Inspection and Assessment Standard for Concrete Strength＂ （GBJ107-87）, the pre-mixed concrete industry develops quickly in recent years. When applying the standard to access inspection of construction engineering, there are some questions relating to how to scientifically judge whether the concrete strength can meet the design＇s demand and technical standards. In this paper, some questions about assessing pre-mixed concrete strength by statistical methods specified in GBJ107-87 and the possible risk of access inspection are discussed.
