| 摘 要： | 发展再生混凝土是我国当前处理废弃混凝土和发展绿色建材的重要途径之一，而再生粗骨料性能的优劣会直接影响混凝土的质量。通过试验手段，分析得到了再生混凝土粗骨料较天然骨料在颗粒级配、吸水率、密度和压碎指标等物理性能方面的差异，为我国今后制定再生混凝土的相关技术规程，大力发展再生混凝土，提供一定的参考依据。

| Abstract: | The development of recycled concrete is one of significant methods to deal with waste concrete and develop green construction material, however, the performance of recycled coarse aggregate has a direct effect on the property of concrete. Through tests on physical performance of recycled coarse aggregate, the differences between coarse aggregate of recycled concrete and natural aggregate are illustrated, such as grading, water absorption rate, density, crushing index and other physical performance, which is serving as a reference to establish related technical regulations, as well as develope recycled concrete. |
