很大一部分基础设施,特别是桥面,暴露在恶劣的环境条件下,并出现早期恶化。因此,建筑中使用的一些材料和设计标准不允许在没有干预的情况下达到结构的预期寿命(超过75年)。为了显著提高基础设施的耐久性,有希望的方法是修订正常强度混凝土(NSC)在服役条件下的设计标准,并促进纤维混凝土(FRC)的使用。与NSC相比,FRC在力学性能和耐久性方面有了显著的改善。然而,在使用中严重缺乏适用的设计标准,阻碍了这些材料在加拿大的充分利用。
英文摘要
Large proportion of infrastructures, particularly bridge decks, are exposed to severe environmental conditions and present an early deterioration. Thus, some materials and design criteria used in construction do not allow reaching the expected lifetime of structures (over 75 years) without intervention. Promising methods to extend significantly the durability of infrastructures are to revise design criteria in service conditions for normal strength concretes (NSC) and promote utilization of Fibre Reinforced Concretes (FRC). Compared to NSC, FRC presents significant improvements in terms of mechanical properties and durability. However, a crucial lack of adapted design criteria in service impedes full exploitation of these materials in Canada.
