Steel Fibre Concrete for Bridge Deck and Building Floor Applications

This paper presents a comprehensive review of the use of steel fibre concrete for bridge decks and building floor slabs. The data shown cover both normal weight and lightweight concrete incorporating steel fibres. Emphasis is given to the mix proportioning of these two concretes to produce workable and compactable mixes without causing fibre bundling, segregation or bleeding. Both material and engineering properties of steel fibre concrete are then discussed in relation to their use in bridge decks and building floors. The structural behaviour of conventional reinforced concrete slabs containing steel fibres is then presented, with particular reference to deformation, cracking, service loads, and failure behaviour. The significant advantages of fibre concrete in structural members are highlighted. It is shown that durability of steel fibre need no longer pose a threat to their use in concrete structures. R.N.
