一种新的检测技术——剪切拉拔综合法

A New Detection Technique——Cutting and Drawing Method

剪切拉拔综合法是在结构上钻制一个直径 44 mm、深度 65 mm 的试件,通过模拟立方体试件抗压破坏时呈现的劈裂抗拉与剪切形态,用采集到的剪切强度和拉拔强度换算混凝土抗压强度,全面反映混凝土中胶凝材料与粗细骨料在混凝土中的作用,用仅有钻芯法体积 7 % 的损害程度,达到或超过钻芯法试验结果的精度,是一种新的检测技术。

Cutting and drawing method that is a specimen with a diameter of 44mm and a depth of 65mm was drilled into the structure,by simulating the cube specimen compressive damage appears when splitting tensile and shear form,shear strength and drawing strength were collected with conversion of concrete compressive strength,fully reflect the gelling material and the thickness in the concrete aggregate in concrete,with only 7% volume more damage,meet or exceed the core method,the accuracy of experimental results,which is a kind of new detection technology.
