Durus EasyShot fibre for concrete

Over the last two decades IGNIS has been used in many tunnels, primarily to provide passive fire resistance to the concrete structure, whether this is a segmental tunnel lining, sprayed or cast in-situ concrete.

Durus S500 is proving increasingly popular with designers, contractors and project owners. This synthetic macro-fibre has shown to be a valid alternative to conventional steel fibre reinforcement. With no need to change existing designs, a concrete mix using steel fibres can be replaced by a mix containing Durus S500 macro fibres. The workability will remain unchanged and often even be improved. Typical applications include the production of concrete tunnel segments and other precast concrete elements. The use of Durus S500 instead of steel fibres eliminates any risk of injuries to manufacturing operatives during dosing, de-moulding and handling of precast elements. Compliance with health & safety requirements during the production process and on the construction site are thus greatly improved.

Durus polypropylene macro-synthetic fibres have revolutionised concrete construction, eliminating the need for steel mesh or fibres in many applications. Durus EasyFinish offers superior performance and cost savings as well as health and safety advantages for concrete suppliers, contractors and designers alike. Durus EasyFinish synthetic macro fibre is extremely easy to handle and apply. The reinforcement comes ready mixed into the concrete or can be added on site – a major advantage over steel mesh, which can be placed incorrectly, affecting quality and production schedules. The fibres are inert to atmospheric conditions, the alkalinity of concrete, and moisture, and therefore 100% rust-free. This makes for a long service life of the finished fibre-reinforced concrete structure.

The Adfil micro synthetic concrete reinforcement portfolio includes a range of high performance monofilament polypropylene fibres. These serve as an alternative to crack control mesh. As such, the fibres enhance the surface properties and durability of cementitious products, significantly reducing the occurrence of plastic shrinkage and plastic settlement cracking.
