100% Recycled Fibres for Concrete

全球每年用最优质钢制造的新轮胎帘线产量约为425万吨。制造过程产生约2%（85，000吨）的废物，其中大部分以高质量钢丝帘线的形式存在，但长度较短，作为轮胎加固材料没有经济价值。在混凝土结构中，在新拌混凝土中加入小的钢纤维是一种提高混凝土抗拉强度和韧性的公认方法。每年有超过1，000，000吨的纤维是由冷拉钢丝生产的。该项目的重点是消除市场障碍，并将这些大量的轮胎帘线废料转化为新的钢纤维产品，用于重负荷混凝土结构，如悬挂板，墙壁和隧道衬砌。为了实现这一目标，将进行研究和技术开发，以提高回收帘线生产的质量评估，将进行详细的生命周期评估，以证明高环保证书，以及结构测试，以确认这种新纤维的性能，并导致认证。这将消除目前的市场障碍，并确保这种创新纤维得到广泛和快速的市场接受。该项目将赋予废弃钢帘线第二次生命，作为混凝土建筑的钢筋，仅需生产新钢纤维所需能源的约1%，从而为循环经济做出贡献，并显着提高建筑行业的可持续性。

Global production of new tyre cord manufactured from the highest quality steel is approximately 4.25 million tonnes per annum. The manufacturing process generates about 2% (85,000 tonnes) of waste most of it in the form of high quality steel cord but in short lengths which have no economic value as tyre reinforcement. In concrete construction the addition of small steel fibres in to fresh concrete is a well established way of enhancing the concrete's tensile strength and toughness. Over 1,000,000 tonnes of fibre is manufactured from cold drawn steel wire for this purpose every year. This project focuses on removing the barriers to market and turning these significant volumes of tyre cord waste into a new steel fibre product for high value applications in heavily loaded concrete structures such as suspended slabs, walls and tunnel linings.To achieve this, research and technological development will be performed to improve the Quality Assessment of the recycled cord production, a detailed Life Cycle Assessment will be undertaken to prove the high environmental credentials, as well as structural testing to confirm the performance of this new fibre and lead to certification. This will remove current barriers to market and guarantee a wide and speedy market acceptance of this innovative fibre.This project will give the waste steel cord a second life as reinforcement for concrete construction, only requiring about 1% of the energy needed to manufacture new steel fibre thereby contributing to the circular economy and significantly improving the sustainability of the construction industry.
