摘要
文章主要介绍利用坍落扩展度、J环、L型盒、V型漏斗、U型箱、坍落扩展度到平均为500mm时的时间(秒数)T500及筛离析实验的办法来方便有效地评价自密实混凝土的高流动性、高稳定性和穿越钢筋间隙能力和自填充能力。
This paper mainly introduces how to make use of slump flow, J-ring flow, L-box, V-funnel, U-box,TS00 and other experiments in order to give effective assessments of flowability, passing ability and segregation resistance of SCC.
