Steel fibre reinforced concrete for structures dates back to 1925, but it is still widely unknown to engineers and contractors. Information is buried in codes, reports and standards; and this book presents the essential information to enable engineers to use steel fibre reinforced concrete, and achieve better results in a variety of conditions.The focus is on its most ready use, in flat horizontal cast in-situ applications -- such as ground bearing slabs, ground suspended slabs, suspended elevated slabs, and raft slab foundations for buildings, which offer more opportunities than three-dimensional structures. Prefabrication and paving is mentioned where it relates to the main applications. Material testing and structural testing are covered in order to explain how to design for these typical applications, and some attention is given to shrinkage and cracking, fire resistance of slabs and walls, and environmental benefits, as well as to future opportunities and challenges.
