Propex Concrete Systems' Concrete Reinforcement Fibres Receive CE Marking

29/07/2008
Propex Concrete Systems' Concrete Reinforcement Fibres Receive CE MarkingThere are new European standards relating to fibres for concrete. As of 1st June, 2008, it is now mandatory for all fibre reinforcement products to have CE marking. Propex Concrete Systems' concrete reinforcement fibres (Novocon, Enduro and Fibermesh) have been granted CE marking. Enduro is the first macro-synthetic fibre to comply with these standards and have CE marking. Click here to read the information sheet. Visit www.propexinc.comPropex's steel fibres Novocon in general are engineered for long-term performance in the more demanding applications. They are designed specifically to enhance the concrete in its hardened state and provide improvements to the flexural toughness, impact resistance and flexural fatigue performance. Additionally, steel fibres provide excellent crack control and maximum load stability at the induced floor joints where it is most needed.There are essentially two different types of synthetic fibres available: macro-synthetic and micro-synthetic fibres.Propex's macro-synthetic fibres Enduro represent a quantum leap in fibre reinforcement technology. Manufactured from high performance polymers, they are designed to offer similar benefits to steel fibres but without the risk of corrosion. The design of these fibres allows for much higher dosage rates than micro-synthetic fibres, thereby infusing the concrete with added levels of crack control, toughness and durability.Propex's micro-synthetic fibres Fibermesh are formulated to address the early age cracking problems of concrete. The uniform distribution of micro-synthetic fibres effectively increases the tensile strain capacity of the early age concrete, thus discouraging the formation of plastic shrinkage cracks. The fibres provide a three-dimensional internal support system that inhibits plastic settlement and results in uniform bleeding. This reduction, or elimination, of plastic cracking enables the concrete to develop its optimum long-term integrity. A further advantage of micro-synthetic fibres is their ability to mitigate the explosive spalling tendancy of concrete during fires. Visit www.fibermesh.com 30/08.
