北京交通大学研究人员开展了高温后高性能混凝土力学性能的试验研究,主要考察了不同类别高性能混凝土的抗压强度、劈裂抗拉强度和断裂能试验结果的差别。研究结果表明:高温冷却后,含粗骨料超高性能混凝土和活性粉末混凝土的抗压强度和劈裂抗拉强度随着经历温度的升高,均呈现先升高后降低的特点;而断裂能随着经
Beijing Jiaotong University researchers carried out the high-performance concrete after high temperature mechanical properties of the experimental study, the main study of different types of high-performance concrete compressive strength, splitting tensile strength and fracture energy test results of the difference. The results show that after high temperature cooling, the compressive strength and splitting tensile strength of ultrahigh performance concrete with coarse aggregate and reactive powder concrete exhibit the characteristics of first increasing and then decreasing with the increase of temperature; however, the fracture With the passage
