摘要
针对我国现行钻芯法规程中没有对直径小于 1 0 0 mm的小芯样砼强度换算方法作出规定 ,而实际工程检测中不少结构或构件因钢筋分布十分密集 ,只能钻取直径小于 1 0 0 mm的芯样 ,为此我们借鉴国外有关标准 ,并结合工程实测 ,探讨小直径芯样砼强度试验应注意的问题及其与标准芯样强度之间的换算关系 .
No special provisions about the conversion formula of small diameter core sample was given in the specification for concrete core sample currently in force when the distance between reinforcing bars is shorter than 100 mm and only small diameter core samples can be acquired in such circumstance .To deal with this problem, some details concerning the experiment of small diameter core sample are discussed here and a strength conversion formula from small diameter core sample to standard core sample is given based on the related standards overseas, which has been verified by the site inspection.
