摘要
研究低掺量情况下混杂(钢-聚丙烯)纤维混凝土各组分对混凝土性能的影响及程度,采用正交试验设计方案,找出混杂纤维低掺量情况下,混凝土在满足强度、工作性(施工性能)、耐久性各方面优良性能时的较优配比,对混杂纤维高性能混凝土进行优化设计。
The article introduces the influence and level of each miscellaneous(steel-polypropylene)fiber concrete constituent under the condition of low mixture on the concrete performance.It is to use the orthogonal test design scheme and to find out the more optimized mixture ratio of the concrete at the excellent performances of meeting the strength,the construction feature and the durability under the condition of low mixture of miscellaneous fibers,and to carry out the optimized design of miscellaneous fiber high-performance concrete.
