Steel fibre<\/a> is used in concrete to control cracks and to make concrete behave less brittle after cracking. Steel fibres sit inside the mix as a distributed network. This gives the concrete some post-crack load capacity, especially in slabs and sprayed concrete. Many projects use steel fibre to reduce mesh handling time. Many projects use steel fibre to reduce floor repairs. These benefits show up most in industrial floors, pavements, sprayed concrete, plus precast elements.<\/p>\n\n\n\n

What is steel fibre reinforced concrete?<\/h2>\n\n\n\n

Steel fibre reinforced concrete (SFRC) is concrete that contains short steel fibres mixed through the whole batch. The fibres act like many small reinforcement elements. They bridge cracks as the concrete starts to open. This helps control crack width. It also helps the slab keep carrying load after first cracking, depending on fibre type and dosage.<\/p>\n\n\n\n

ASTM C1116 is the common supply specification for fibre-reinforced concrete. It covers fibre concrete delivered with ingredients uniformly mixed. It also defines Type I steel fibre-reinforced concrete<\/strong> and links it to steel fibre requirements in ASTM A820\/A820M.<\/p>\n\n\n\n

Steel fibres are used most in slab and pavement work. The Concrete Society highlights industrial floors and pavements as major applications. It also lists sprayed concrete, composite slabs on steel decking, plus precast elements as key applications.<\/p>\n\n\n\n
