ANALYSIS FOR TEMPERATURE RISING OF CRTS Ⅱ TRACK BOARD CONCRETE FOR HIGH-SPEED RAILWAY
-
摘要: 通过分析不同施工环境温度,不同矿物掺合料及不同施工配合比条件下CRTSⅡ型轨道板混凝土温升过程,提出有利于加快轨道板预应力筋放张,缩短脱模时间,提高轨道板生产企业生产效率的措施。Abstract: By analyzing the process of temperature rising CRTSⅡ track board concrete in the conditions of different construction ambient temperature,different mineral admixture,and different concrete mix,it is put forward the measures for speeding up the tensioning of reinforced concrete,shortening ejection time of concrete and improving the economic efficiency of enterprises.
