混凝土取芯方向与芯样抗压强度关系试验研究

Research on the connection between the coring direction and the compressive strength of concrete core

通过试验制取了取芯方向与混凝土浇筑成型方向平行或者垂直的大量混凝土芯样,推定出了在同条件养护状态下取芯方向对芯样强度有一定影响,当进钻方向与混凝土成型方向平行时,比与成型方向垂直时取出的芯样强度要高1.051倍,对工程实践具有指导意义。

Under the same condition,core-drilling direction had a certain effect to the concrete compressive strength through a large concrete core samples whose core-drilling was parallel or vertical to concrete casting molding direction.The strength of core samples whose core-drilling was parallel to casting molding direction was 1.051 times than whose core-drilling was vertical to casting molding direction.This result has in- structive significance to the project practice.
