混凝土结构实体强度现场检测技术探讨

Applicability Research on Testing Technology of Physical Strength of the Concrete Structure in Curtain Wall

通过混凝土结构实体强度不同检测方法—回弹法、超声回弹综合法、钻芯法,对同条件养护28d、600℃.d、60d、90d四个龄期的混凝土试块的检测结果进行比较,得出了混凝土结构实体强度不同检验方法检测结果的差异,提出了针对不同情况检测方式的选择方法。

By different testing methods of physical strength of the concrete structure -- rebound method, ultrasonic-rebound combined method, core drilling method, testing results of four instars concrete specimens of conservation of 28 days, 600℃·d, 60 days, 90 days on the same conditions were compared, differences of testing results by different detection methods of physical strength of the concrete structure were obtained, and the choice of testing methods according to different situations was put forward.
