本文针对国内外绿色混凝土再生骨料的利用现状,指出绿色混凝土再生骨料的再利用势在必行,再生骨料的性能直接影响着再生混凝土的特性,因此研究好再生骨料的特性,对提高再生混凝土的质量非常重要。本文在参考国内外文献和课题试验的基础上,详细地阐述了再生骨料不同于天然骨料的基本性能,对再生混凝土骨料的性能包括级配、坚固性、吸水性等性能进行一些研究,最后对再生骨料的再利用提出了建议,供相关单位参考。
This paper aims at the utilization status of recycled concrete aggregates at home and abroad, and points out that the reuse of green concrete recycled aggregates is imperative. The performance of recycled aggregates directly affects the characteristics of recycled concrete, so the characteristics of recycled aggregates are studied. It is very important to improve the quality of recycled concrete. Based on the references of domestic and foreign literatures and research projects, this article describes in detail the basic properties of recycled aggregates that are different from natural aggregates, and conducts some studies on the properties of recycled concrete aggregates including gradation, sturdiness, and water absorption properties. Finally, suggestions were made for the reuse of recycled aggregates for reference by related parties.
