Abstract
In view of freze thaw cycles and vulnerability to frost damage of the concrete in the alpine area,how to im-prove the frost resistance of concrete is the key.This paper describes the study on the frost resistance of pavement concrete in alpine area,focusing on the effects of the water-binder ratio,sand ratio,adhesive materials and air content on the frost resistance of pavement concrete.The results show that on the premise of meeting the pavement concrete design index and field construction performance,increasing the amount of the adhesive materials,reducing the water-binder ratio,sand ratio and air content are conducive to improving the frost resistance of the pavement concrete.Ac-cording to the above design,the grade of the frost resistance of pavement concrete can reach F300.The study results have a certain guiding significance for the pavement concrete in alpine area.关键词
