Non corrosive reinforcement of concrete on the basis of artificial fibres
In the production of concrete elements non-corrosive or metal-free reinforcement is demanded quite frequently. The applications are various, such as concrete elements in corrosive environments, concrete structures with tightness requirements, reinforcement transitions at building joints, replacement of conventional steel reinforcement, reduction of the crack with by textiles near the surface of the concrete etc. As reinforcement for these applications essentially two systems are possible: (i) a fibre reinforcement additionally installed to the steel reinforcement on the basis of long fibres as a technical textile, and (ii) exclusive use of fibre-reinforced plastic-bars (FRP-bars) in concrete. 10 different beams made of bi and tri axial warp knitted and stitch-bonded fabrics and e-glass as well as carbon fibres have been used. The bon behaviour, fatigue strength and durability of the bars have been investigated. Non corrosive reinforcement of concrete on the basis of artificial fibres helps to design pretentious building constructions under severe conditions regardless of whether additional steel reinforcement is used or not. Especially where the environment requires to reduce the crack width, thermal conductivity and electromagnetic fields these non-steel materials show great efforts in reaching the desired properties of the building. Additionally the low thermal, magnetic and electric conductivity introduce special fields of usage like optimised cantilevered slab joints or the use in sensible areas like hospitals or storage ring accelerators.
