摘要
通过对水泥、砂浆和混凝土不同性能的触变扰动试验 ,获得各自的触变规律 ,得出控制混凝土触变性能的参数 ,确定了最佳触变时间 ,分析了相关因素对混凝土触变性能的影响 ;最后通过爆炸冲击试验得出混凝土受高温高压作用下发生触变前后的结果 ,结合同步实现爆炸成型地下仓和混凝土仓壁的模型试验 ,为混凝土触变性能的应用提出理论基础。
? The thixotropy of fresh cement paste,mortar and concrete were gained after they were vibrated or agitated,the factros for controllng the thixotropy and the optimum thixotropy time of concrete were concluded.Based on the thixotropy tests under high temperature and high pressure with explosive shock method,and the simulated tests of building underground cavity and forming concrete support,a theoretical basis for the application of concrete's thixotropy is provided. 〔
