摘要
沈铁高速公路改扩建起点接王家沟枢纽互通,终点接杏山枢纽互通,全线长度左线152.648km,右线153.086km。桥梁结构中有抗冻、抗渗、抗侵蚀要求的地面以上构件采用引气抗冻混凝土。介绍了引气抗冻混凝土的性质及配合比控制,阐述了混凝土缺陷的防治措施。
The starting point of reconstruction and extension of Shentie expressway is connected to Wan^jiagou interchange, and end point is connected to Xingshan interchange, with a total length of 152. 648km from left and 153.086km from right. Air - entraining frost - resistant concrete is adopted for ground with anti - freeze,impervious and anti - erosion requirement in bridge structure, nature and mix proportion control of air - entraining frost - resistant concrete are introduced, and prevention measures for concrete defect are elaborated.
