摘要
混凝土的结构组分决定其力学性质,同时影响超声波在其中的传播。通过试验研究和数据处理分析,得到了对混凝土声-应力关系最为敏感的骨料粒径、骨料种类、水灰比和砂率,为混凝土工作应力声测技术的研究提供了试验基础。
The influence in the structural constituents in concrete will decide the mechanical property of the concrete and will meantime the propagation of ultrasounds in concrete. From the experimental studies and the analysis of the data available, the particle size, type of aggregate, water-cement ratio and sand percentage are derived, which are the most sensitive factors to the correlativity of ultrasound and stress in concrete, thus laying a experimental foundation for the research in the stress-ultrasonic technique for concrete testing.
