钻入试验评定火灾后混凝土强度的改进方法

The improvement method of drilling test in the assessment of post-fire concrete strength

通过钻头钻入混凝土中来评定火灾后混凝土的强度具有一定的可行性,但只能得到构件某个受损深度上的平均强度。文章通过对钻头和试验方法的改进,能够测试到火灾后混凝土受损深度上强度的变化。

Using bits to drilling into the concrete to evaluate the strength of the post-fired concrete is feasible, but only the average intensity of a damaged depth of the component could acquire. In this paper, by the envisaged improvements of the drill and test methods of such measuring means, it is expected to be able to reflect the change of intensity in the damage depth.
