摘要
无砟轨道施工过程中,自密实混凝土是重要的一个环节,在正式进行灌注前,需要通过揭板试验,来实地检验自密实混凝土工作性能,确定自密实混凝土的原材料及施工配合比,掌握自密实混凝土的性能指标和施工工艺参数,为自密实混凝土施工应用积累经验。
Self-compacting concrete is an important part in the construction of ballastless track. Before the formal infusion, it is necessary to pass the slab uncovering test to test the working performance of self-compacting concrete, determine the raw materials and construction mix ratio of self-compacting concrete, and master the performance index and construction process parameters of self-compacting concrete, to gain experience for self-compacting concrete construction applications.
