However, as normal concrete generally has low strength, the thickness of concrete slabs is large. Consequently, the self-weight of the bridge deck is heavy, which increases the dead load of the bridge. In addition, the concrete decks are vulnerable to cracking in negative bending moment zones....
超高性能混凝土(Ultra-HighPerformance Concrete),简称UHPC,国际上系指抗压强度在150MPa以上,同时具有超高韧性、超长耐久性的水泥基复合材料的统称。其中,最具代表性的超高性能混凝土材料为活性粉末混凝土RPC(Reactive Powder Concrete),最早由法国学者于1993年研发成功,主要由水泥、硅灰、细骨料、减水剂及钢纤维等材料组成,...
