摘要:
优良韧性是钢纤维混凝土这一新型结构工程材料的显著特点。本文总结了钢纤维混凝土的各种有代表性的弯曲韧性指数,对它们的应用进行了分析与评价,并根据材料的脆性特点讨论了钢纤维混凝土的韧性指数体系。
An excellent toughness is the significant properly of steel fibre reinforced concrete which is a new type of structural material. Various representative indexes of the bending toughness of steel fibre reinforced concrete are summerized and their application is analysed and appraised. The toughness index system for steel fibre reinforced concrete is also discussed on the basis of the brittleness of materials.
