本文研究了DG系列高效活化剂对高掺量 (50 %～ 70 % )粉煤灰混凝土能的影响。通过系统的实验证明 ,研制的DG系列高效活化低标准粉煤灰 (Ⅱ级灰 )有良好的激活作用。分虽用 1 0 0Kg ,1 50Kg,2 0 0Kg,2 4 0Kg和 2 90Kg普水42 5#水泥结合DG系列活化剂配制出上有良好可泵性 (坍落度均在 2 0cm± 2cm)C 7.5 ,C 1 0 ,C 2 0 ,C 2 5 ,C 35级混凝土 (以2 8天强度计 ) ,56天强度均可提高一级标号 In this paper, the effect of high efficiency activating agent of DG series on the energy of high content (50% ~ 70%) fly ash concrete was studied. Through systematic experiments, it is proved that the DG series of high activation activated low standard fly ash (grade Ⅱ ash) has a good activation effect. Although with 200Kg, 150Kg, 200Kg, 240Kg and 2 90Kg Pushi 42 # cement combined with DG series activator formulated with a good pumpability (slump in 20cm ± 2cm) C 7.5, C 1 0, C 2 0, C 2 5, C 35 concrete (with 28 days intensity meter), 56 days intensity can be increased by a level label
