低温时期混凝土路面施工研究

Study of Low Temperature Period Concrete Pavement

本文分析了混凝土冻害发生的原因,深入探讨了混凝土冻害的影响因素,从原材料的选择、配合比、混凝土的浇筑、养生等方面提出了混凝土的防冻措施,以完善低温时期的混凝土路面施工工艺,避免冻土地区公路发生冻害。

Analyzed the reasons of the occurrence of concrete frost,probes into the influence factors of concrete frost,through the choosing of raw materials,mixing ratio,concrete pouring and curing etc.To put forward concrete anti-freeze measures to perfect the low temperature period of concrete pavement construction craft,avoid the permafrost region highway happen cold.
