摘要

节土坝、防波堤和路面处于严重的磨损状态,结构往往会发生快速劣化。超过200mpa的超高强度混凝土,不论有无钢纤维,都有可能成为高耐磨性混凝土。研究了钢纤维掺量、水胶比和压实方式对超高强度钢纤维增强混凝土耐磨性和力学性能的影响。结果表明,在超高强砂浆中掺入钢纤维与热压密实相结合是改善超高强砂浆性能的有效方法

STRENGTH AND ABRASION RESISTANCE OF ULTRA-HIGH STRENGTH STEEL FIBER REINFORCED CONCRETE
Synopsis Soil saving dam, break water and pavement that are located in severe wearing condition are often subjected to rapid deterioration of structure. Ultra-High strength concrete exceeding 200 MPa with or without steel fiber, has a possibility of becoming high abrasion resistance concrete. The effect of addition of steel fibers, water-binder ratio and compaction method on abrasion resistance and mechanical properties of ultra-high strength steel fiber reinforced concerete were studied. It was concluded that, the combination of addition of steel fibers and using hot-press compaction for ultra-high strength mortar is particularly effective in improving
