L-800 rheological testing apparatus of concrete mixtures was used to study influences of pre-water absorbed time and mortar wrapped method on workability of self-compacting lightweight aggregate concrete.
针对自密实轻骨料混凝土拌合物在大流动度条件下,易于分层而导致工作性不良的现象,采用自行设计的L-800混凝土拌合物流变性能测定仪,研究预吸水和表面裹浆法两种轻骨料预处理工艺对自密实轻骨料混凝土拌合物工作性能的影响。
