摘要
薄壁墩因结构特殊,受外界气温影响明显,施工时容易产生温度裂缝。通过大量试验,以混凝土抗裂性能为评价指标,优化混凝土配合比组成,成功配制出了适用于西部大温差地区某桥梁薄壁墩结构的高性能混凝土,为混凝土施工提供了有力的保障。
It was easy to produce temperature crack for thin wall pilla, which was effected obviously by outside temperature because of its special structure. In this article, high performance concrete applied to some thin wall pilla structure was worked out successfully in the west of china with big temperature gap by a large number of experiments, in order to improve cracking resistence and optimize mix of concrete, which will be helpful in improving concrete construction.
