再生骨料注浆料及注浆再生混凝土性能研究

Study on Properties of Recycled Aggregate Grouting Material and Grouting Recycled Concrete

针对旧水泥混凝土路基和基层裂缝、路面板底脱空等病害的加固和修复,通过试验研究了再生骨料注浆料的流动性和力学性能,并在此基础上进一步分析了注浆再生混凝土的力学性能。研究结果揭示了再生细骨料用量、环境温度与再生骨料注浆料流动性之间的关系,以及再生细骨料用量和水胶比对再生骨料注浆料、注浆再生混凝土力学性能的影响规律。

In view of the reinforcement and the repair of the old cement concrete roadbeds, the subgrade cracks, and the bottom cavity of pavement plates and so on, the fluidity and mechanical properties of the recycled aggregate grouting material are studied by the tests. Moreover, the mechanical properties of the grouting recycled concrete are further analyzed. The study results show the relationship among the recycled fine aggregate dosage, the ambient temperature and the fluidity of recycled aggregate grouting material, as well as the influence law of the recycled fine aggregate dosage and the water-binder ratio on the mechanical properties of the recycled aggregate grouting material and the grouting recycled concrete.
