【摘要】 进行了一批聚丙烯腈纤维自密实混凝土工作性的测试试验,采用J环试验的测试结果表征自密实混凝土的工作性,对纤维自密实混凝土工作性及其相关因素进行灰色关联分析,进而得出相关因素的关联度排序,为纤维自密实混凝土工作性的试验研究提供基础性资料。更多还原

【Abstract】 Based on the workability test of polyacrylonitrile fiber reinforced self-compacting concrete,the workability of self-compacting concrete was denoted by the results of J-ring test.The workability of fiber reinforced self-compacting concrete and it’s correlation factors are analyzed by grey system theory.The analysis result can be applied to engineering practice.更多还原
