摘要
根据无砟轨道充填层对自密实混凝土的要求,介绍了自密实混凝土的性能指标,阐述了C40自密实混凝土的配合比设计方案,并通过现场灌板揭板工艺性试验,优化了混凝土配合比。
According to ballastless track filling sequence demands for self-compacting concrete, the paper introduces self-compacting concrete performance index, and describes C40 self-compacting concrete mixing proportion design scheme. Through in-situ pouring-plate technology exper-iment ,it optimizes the mixing proportion.
