高性能混凝土在河北省北部地区桥梁中的应用研究

高性能混凝土是一种新型高技术混凝土，具有较好的耐久性、工作性、适用性、强度、体积稳定性及经济性。河北省北部地区受寒冷气候条件影响，桥梁混凝土冻害、腐蚀病害较普遍，针对该地区原材料实际状况，提出该地区主要原材料的技术指标要求，为高性能混凝土推广应用提供指导。

Application of High-Performance Concrete in Bridges in Northern Heibei

High-performance concrete is a new type of high-tech concrete with good durability, workability, suitability, strength, volume stability and economy. In the north of Heibei, influenced by the cold climatic conditions, the frost damage and corrosion disease of bridge concrete are prevalent. In accordance with the raw materials in these areas, their technical requirements are proposed which would provide guidance for the promotion and application of high-performance concrete.
