摘要
通过工程实践,介绍了机制砂掺加粉煤灰在隧道衬砌C20泵送混凝土中的选料、配合比要求、泵送的施工要求及性能指标,并用具体数据分析论证了机制砂掺加粉煤灰施工的良好经济效益和环保作用,为类似工程提供了施工经验。
Through the project practice,it introduces the construction requests and performance index of machine-made sand mixing fly ash in selection,adapted ratio requests,pumping of tunnel lining C20 pumping concrete,and using the specific data,it analyses and illustrates the good economical benefits and environment protecting action of machine-made sand mixing fly ash construction,and this supplies the construction experience to similar projects.
