摘要
采用全计算法对客运专线高性能混凝土进行了配合比设计,并在此基础上研究了粉煤灰掺量对混凝土力学性能及耐久性能的影响,试验结果表明,全计算法是一种更科学、更合理、更准确的配合比设计方法,为提高混凝土的耐久性,应该在保证混凝土早期强度的前提下尽可能多掺加矿物掺合料。
Utilizing overall calculation method mix proportion design of high-performance concrete in special railway line for passenger transportation is introduced The influences of additive amount of fly ash on mechanical properties and durability of concrete are analyzed, test results show overall calculation method is a more scientific, accurate and reasonable method for mix proportion design.
