不同强度及粗骨料对混凝土断裂能影响的实验研究

Experiment Researching on Aggregate in Different Strength and Coarse Aggregate Having Impact on Concrete Breaking Energy

对不同强度的卵石及碎石混凝土进行了三点弯曲的实验。结构表明,混凝土的强度是影响混凝土断裂能的主要因素,而相同强度不同骨料的混凝土,其断裂能也有所不同,由卵石做骨料的混凝土强度略高。

The bending experiments at three points to pebble and macadam concrete in different strength have been conducted. Results show that the concrete strength is a chief major factor affecting the concrete breaking energy ,while different aggregate concretes in the same strength have also different breaking energy. But, the strength of concrete as aggregate with pebble is slightly high.
