利用自密实混凝土(Self Compacting Concrete)的高流动、抗离析性能好以及自流动等特点,采用大粒径的块石作为骨料堆积入模后,填充自密实混凝土,从而形成一种堆石混凝土(RFC)。文中研究制作了大尺寸自密实堆石混凝土试件,在500 t电液伺服试验机上进行抗压强度试验,对照已有的标准混凝土试件试验结果,研究大尺寸试件内部自密实混凝土与大粒径骨料(块石)之间的粘结状况和试件的整体力学性能。
Using self-compacting concrete (Self Compacting Concrete) high flow, good anti-segregation performance and self-flow characteristics, the use of large-size stone as aggregate into the mold after the accumulation of self-compacting concrete to form a pile Stone Concrete (RFC). In this paper, a large-size self-compacting rockfill concrete specimen was fabricated and tested on a 500 t electro-hydraulic servo testing machine. Comparing with the existing test results of standard concrete specimens, the effects of self-compacting concrete Particle size aggregate (stone) bonding between the state and the overall mechanical properties of the specimen.
