摘要
以新建兰新铁路第二双线新疆段高性能混凝土为研究对象,结合沿线气候特点,介绍了砂石原材料质量控制、沿线混凝土结构环境作用等级的划分以及配合比试验、原材料及混凝土温度、混凝土养护等方面的质量控制具体措施,对确保兰新铁路第二双线新疆段高性能混凝土的强度和耐久性具有重要意义。
Based on the study of high performance concrete in Xinjiang section on 2^nd double line of Lanzhou-Xinjiang railway, and weather along the railway, the author introdneed the sandstone quality control, rating divide of environment action for concrete structure along the railway, and detailed quality control measurement about mixture ratio test, temperature of materials and concrete, concrete curing and so on was introduced.
