富含砖粒的再生混凝土试验研究

Experimental research on recycled-concrete with rich brick granule

通过试验,采用富含砖粒的再生骨料配制混凝土,根据所配制的再生混凝土需水量和力学性能,探讨了富含砖粒的再生骨料对混凝土性能的影响,同时通过CT扫描试验,分析了试件在不同荷载下内部结构变化情况,研究了再生混凝土细观损伤的特征及裂纹萌生和发展的重点分布部位,为进一步研究再生混凝土细观破坏机理和裂纹开展规律奠定基础。

Through experiments, applying aggregated recycled-concrete with rich brick granule, according to recycled-concrete water quantity and mechanical properties, the paper explores the impact of aggregated recycled-concrete with rich brick granule upon concrete performance. Through CT scanning test, it analyzes internal structure alteration conditions of experimental components under different loading conditions, and studies meso-damage characteristics of recycled-concrete and crack initiation and development distribution parts, which has laid a foundation for further studying meso-damage damage characteristics of recycled-concrete and crack initiation development law as well.
