摘要
经研究大掺量粉煤灰自密实混凝土(HVFASCC)的配合比设计方法,建立了HVFASCC浆体含量计算模型,试配了HVFASCC,测定了其坍落扩展度和强度。试验结果表明,浆体含量计算模型适用于HVFASCC配合比设计;HVFASCC中应优先掺用聚羧酸盐减水剂,可不掺用细粉料。
The aim of this paper is to put forward a method for designing high volume fly ash self compacting concrete （HVFASCC）. The matrix volume calculation model was built by authors. HVFASCC were mixed, slump flow as well as strength of them was verified by experiments. The test results indicate thatmatrix volume calculation model may be used as a method for mix design of HVFASCC; polycarboxylate based superplasticizer is the first selection for HVFASCC; no use of powder filler is capable for HVFASCC.
