【摘要】 制备出了一种快速修复路面用钢纤维混凝土,研究了钢纤维品种、施工工艺与粗骨料粒径对混凝土强度等性能的影响。发现不同品种的钢纤维对混凝土强度影响显著,钢纤维的长度与粗集料的最大粒径之间存在密切相关性,最优集料最大粒径可以根据钢纤维的几何尺寸计算出。并且提出了较优的混凝土施工工艺,该种混凝土的工程应用效果及耐久性良好。更多还原

【Abstract】 A kind of steel fiber concrete was prepared,which is used for rapid repairing of concrete road.The influences of steel fiber sort,mixing technology of fresh concrete and coarse aggregate size on the properties of steel fiber concrete were studied.The test results show that the steel fiber sort has important influence on the concrete strength,and the relationship between steel fiber length and coarse aggregate size is tied up,and the best aggregate size could be calculated by the steel fiber length.The best mixing technologies of fresh concrete were also put forward. The engineering application of the concrete proved behaviours well.更多还原
