小直径混凝土芯样抗压强度应用性研究

Research on the Usability of Compression Strength of Small Diameter Concrete Sample

通过采用当地原材料进行试验,着重研究了Φ75 mm×75mm混凝土芯样强度值与150mm×150mm×150mm同条件的混凝土试块强度值之间的相关关系,建立了高径比为1的Φ75mm芯样强度与边长150mm立方体强度之间的修正系数,为采用小直径芯样测强和建立地区性测试规程提供了基础性资料。

According to the experiment of local material, the relationship between the concrete sample strength with the size 75mm×75mm and the size 150mm×l50mm×l50mm under the same conditions was researched. The modify coefficient between the column sample with the ratio of high/diameter l/Ф75mm and the cubic sample with the edge length 150mm was setup. The basic data was provided for the small diameter sample strength and local test regulation compile was provided.
