摘　　要：研究了铁板砂岩陶粒最大粒径、胶凝材料用量、砂率、矿物掺合料、外加剂、陶粒预吸水对铁板砂岩陶粒混凝土工作性能的影响规律。阐述了铁板砂岩陶粒混凝土拌合物浆体的特征以及工作性能的控制方法。基于对铁板砂岩陶粒混凝土的坍落度、扩展度、分层度和泌水度等因素的分析得出了对工作性能的评价方法。采用铁板砂岩陶粒混凝土配合比优化配制技术,配制出了工作性能良好的铁板砂岩陶粒混凝土。The effects law of the maximum particle size,cementious material dosage,sand ratio, mineral admixtures, additives, the pre-absorption of eeramsite on the working performance of iron sand ceramsite concrete were studied. The control method of working performance and characteristic of iron sand ceramsite concrete mixture slurry were set forth. Based on the analysis of slump,divergence,stratification,bleeding of iron sand ceramsite concrete,evaluation method of the work performance was considered. The iron sand ceramsite concrete with good working performance was prepared by using the mix ratio optimization preparation technology.
