摘要
对再生混凝土粗集料(d≥5mm)的基本性能进行较为系统的试验和研究,主要内容包括相对粗糙度、表观密度、吸水率、含泥量、洛杉矶磨耗、压碎值和坚固性等,并将其与普通混凝土粗集料的相关性能进行对比分析,以寻找它们之间的差异,为废弃混凝土在道路工程中的应用提供参考。
The basic performances of RCA were investigated and analyzed,including roughness,apparent-density,water-absorption,mud-content,ratio of LA,etc,which were compared to those of NCA to search for the difference belween RCA and NCA,these tests could offer a reference for the use of RCA in road engineering.
