提高水泥混凝土路面和机场道面基建投资的效益,在于延长路面与道面的使用期限。水泥混凝土路面过早的大修,常常是路表出现了不同程度的剥落,而混凝土不耐冻的组织结构是引起这种破坏的原因之一。解决水泥混凝土耐久性的问题,应考虑到原材料的性质、混合料组成、混凝土 Improve the investment benefits of cement concrete pavement and airport pavement infrastructure is to extend the use of pavement and pavement. Premature overhaul of cement concrete pavement often leads to different degrees of spalling on the road surface, while the structure of concrete that is not resistant to freezing is one of the causes of this damage. Solve the durability of cement concrete problems, should take into account the nature of raw materials, mix composition, concrete
