鋼繊維補強超高強度コンクリートの強度および耐摩耗性

抄録

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 abrasion resistance.
