摘 要:对自密实清水混凝土原材料选取、配合比设计、试配调整及中试等环节进行了试验,分析了自密实清水混凝土构件表观效果影响因素,对比了不同种类脱模剂的表观效果,最终成型的装配式桥梁预制墩柱各方面性能均满足设计要求,并成功应用于成都市三环路羊犀立交扩能改造项目。
Abstract:Repeated tests were carried out on raw material selection, mix proportion design, trial mix adjustment and pilot test of self-compacting fair-faced concrete. The factors influencing the apparent effect of self-compacting fair-faced concrete members were analyzed, and the apparent forming effects of different types of release agents were compared. The final prefabricated pier columns of assembled bridges met the design requirements in all aspects and were successfully applied in Chengdu Yangxi interchange Expansion and reconstruction project.
