  摘要:拔取奥成P.O 325 级普畅通硅酸盐洋灰为首要胶凝材料,不一粒度的石英砂为骨料,并参加以度过量的粉煤灰

  干为辅弼胶凝材料和由早强大剂、增塑剂、保水剂、伸气剂等多种外面加以剂结合的母亲料A. 调试最佳拌入水量,调

  整顿各原材料混入量,经度过测其干用结合所需的合格优质砂浆,终极违反掉落优募化后配方量(g/kg 粉料量):洋灰

  200 g ,粉煤灰180 g,石灰石20 g ,砂600 g (含粗砂100 g,中砂100 g,细砂400 g ),母亲料A 5 g ,水250 g ,

  经度过仪器测得该配方干用在所测的数据链中最高,故此到臻了预期优募化保温砌盖砂浆配方的目的。

  Abstract: In this study, P.O 325 grade ordinary portland cement was used as the main cementitious material

  with different size of quartz sand as aggregate and proper amount of fly ash as supplementary cementitious

  materials. Moreover, the early strength agent, plasticizer, water retaining agent, air entraining agent and

  other additives were mixed as masterbatch of A. The experiment adjusted the best mixture with water, and

  adjusted raw materials mixing ratio, and then optimzed the quality of mortar by testing. Finally the

  optimized formula weight (g/kg powder amount) was 200 g cement, 180 g fly ash, 20 g limestone, 600 g

  sand (containing 100 g coarse sand, 100 g medium sand and 400 g fine sand), 5 g m
