摘要:
原位单剪法检测混凝土抗压强度技术,是在混凝土结构面上钻成直径44 mm、深度40 mm的芯样,将装有左右卡头的剪切头套住芯样后,通过施加剪力将混凝土芯样在深度25 mm处剪断。用该处的混凝土抗剪强度推定混凝土抗压强度。The technique of in-situ single-shearing core for testing concrete compressive strength, drill a core sample with diameter 44 mm, depth40 mm, and snare the core with shearing-head, which has left and right part. By applying shear force on the core, and cutting off25 mmdepth. According to the core’s concrete shear strength, presume the core’s concrete compressive strength.
