摘要
实验研究了爆炸冲击作用下混凝土触变后的强度和微结构特征.结果表明,混凝土触交后的微结构与爆炸荷载强度、混凝土含水量及骨料有关.触变后的混凝土强度高于正常凝结混凝土强度,提高程度决定于爆炸应力波强度和混凝土的微结构.
The strength and microstructure of con- crete after thixotropy under blasting are studied by tests. Results indicate that the microstructure of concrete after thixotropy is related to blasting, wa- ter content and aggregate of concrete. The strength of concrete after thixotropy is higher than that nor- mally congealed, and the increase of strength de- pends on the intensity of blast wave and microstruc- ture of concrete.
