介绍高抗冻和抗盐冻剥蚀性混凝土高等级公路的设计、试验和施工的情况。实验室和现场撒盐破坏均表明在保证等抗压强度、等水泥用量和坍落度的条件下 ,按抗冻 (包括盐冻 )耐久性设计的混凝土 ,其抗冻 (包括盐冻 )性与原施工混凝土相比有本质的改善 Describe the design, testing and construction of high-grade high-freezing and salty-denudated concrete roads. Laboratory and on-site saltwater destruction indicate that concrete designed for durability against freezing (including salt frost) has antifreeze (including salt frost) properties, such as guaranteed compressive strength, equivalent cement content, and slump Compared with the original construction of concrete has a substantial improvement
