| 摘 要： | 混凝土由于受硫酸盐侵蚀和干湿循环作用,内部出现微损伤,性能发生劣化.目前国内外针对结构混凝土硫酸盐侵蚀和干湿循环作用对结构混凝土的损伤失效的研究都集中在力学性能方面,关于损伤和劣化规律特别是无损检测的实验研究较少.混凝土无损检测技术一般采用线性超声方法,用非线性声学方法检测混凝土损伤和劣化规律的研究才刚刚起步.岩石、混...

| Abstract: | When concrete is under sulfate erosion and the wet and dry cycles,the internal micro-damage and performance degradation occur.Studies on structure concrete that is under sulfate erosion and the wet and dry cycles is not enough,the research at present is focused mainly on the mechanical properties of structure concrete.There are few works on the internal micro-damage and the performance degradation of structural concrete.Concrete nondestructive testing techniques are generally using linear ultrasonic method.... |
