低水胶比机制砂高性能混凝土的最优配比的确定

Optimal proportion of low water-binder ratio manufactured-sand high-performance concrete

本文采用调优操作最优化方法、正交试验设计法、综合评分法对低水胶比机制砂高性能混凝土的配合比进行了系统的试验研究,并用MATLAB统计软件进行计算,成功配制出工作性和抗压强度都较好的低水胶比高性能混凝土。对影响低水胶比机制砂高性能混凝土工作性和力学性的主要因素进行了分析,确定出配制低水胶比机制砂高性能混凝土的最显著影响因素和最优配合比,所得结论为低水胶比机制砂高性能混凝土的进一步研究与应用提供了参考。

This paper applies the optimal method of evolutionary operation,orthogonal design and comprehensive assessment to experiment and research on the proportioning of low-water-binder ratio manufactured-sand high-performance concrete in a systemic manner.Statistical software ＂MATLAB＂ is also used for calculation purposes in this paper to successfully compound low-water-binder manufactured-sand high-performance concrete with good functions and compressive strength.I also analyze various factors effecting the functions and mechanical properties of low-water-binder manufactured-sand high-performance concrete,and find out the most fundamental elements and optimal proportioning of compounding it.My conclusion provides some insights for further research on and application of low-water-binder manufactured-sand high-performance concrete.
