摘　　要：用有效芯祥试件混凝土的抗压强度值中的最小值确定单个构件混凝土强度推定值,其结果偏低,建议用芯样平均值或中间值作为单个构件混凝土抗压强度推定值,建议用芯样强度推定值不小于规定抗压强度的0.85倍,芯样最小值不小于规定抗压强度的0.75倍作为单个构件混凝土抗压强度混凝土合格评定标准。Appointing the minimal compressive strength of the core samples as estimated strength of single concrete element in CECS03:2007 Technical specification for testing concrete strength with drilled core is underestimated,suggesting the average compressive strength or the middle strength of the core samples as the estimated strength of the single concrete element,and the estimated compressive strength of the core samples ≥0.85 specified compressive strength as well as the minimal strength of the core samples ≥0.75 specified compressive strength as qualified criteria.。

关 键 词：抗压强度推定值 平均抗压强度 单个构件
