抗冻耐久水泥混凝土在沈平高速公路改扩建工程中的应用研究

摘要

结合辽宁省沈阳至四平高速公路改扩建工程建设,针对抗冻耐久水泥混凝土在公路工程中的应用,从水泥混凝土的配合比设计,抗冻、抗渗耐久性评定,施工工艺优化等方面进行阐述,论述了应用抗冻耐久水泥混凝土的注意事项,并对应用成果进行社会经济效益分析.%In combination with the reconstruction and extension project construction of Shenyang-Siping Expressway in Liaoning province, aiming at the application of frost-resistant and durable cement concrete in highway engineering, some matters like mix design of cement concrete, frost-resistant and anti-permeability durability evaluation, construction technology optimization and so on are elaborated, matters needing attention in the application of frost-resistant and durable cement concrete are discussed and the application achievement is made.
