钢纤维增强聚合物高强混凝土疲劳性能的试验研究

Experimental Research on Fatigue Performance of Steel Fiber Reinforced Polymer High-strength Concrete

通过对钢纤维增强聚合物高强混凝土材料进行疲劳试验,研究钢纤维和聚合物乳胶的掺入对高强混凝土疲劳性能的增强的机理。结果表明,钢纤维和乳胶的掺入能够抑制裂纹的发展,提高混凝土的断裂韧性,使得在应力不变的条件下较大幅度地提高了高强混凝土的疲劳性能。

By testing the fatigue performance for the steel fiber reinforced polymer high-strength concrete,the reinforcing mechanisms of the fatigue performance of polymer emulsion and steel fiber are studied.The experimental results indicate that mix polymer emulsion and steel fiber in high-strength concrete can restrain the development of cracks and improve the fracture toughness of concrete.It makes great improvement on the fatigue properties of high-strength concrete.
