Reuse of Tyre Fibres for Fire-Spalling-Proof Concrete ...

Jul 01, 2016  In WP2, concrete specimens, with and without Recycled Tyre Polymer Fibre (RTPF) have been tested at high temperature, showing that RTPF has a strong potential to replace manufactured polypropylene fibres for the mitigation of fire-induced spalling in concrete construction. In WP3, numerical heat transfer analyses were conducted.

REUSE OF TYRE STEEL FIBRES AS CONCRETE REINFORCEMENT

To attain economically viable and environmentally friendly tyre recycling, it is necessary to develop new applications and products, which will use tyre by-products (especially the steel cord) as raw materials. The authors demonstrate that the steel fibres recovered from used tyres can be used to reinforce concrete elements.

Feb 19, 2019  Thousands of tonnes of polymer and steel fibres are generated each year in Europe alone, as by-products of recycling (mainly for recovering rubber) of end-of-life tyres. These fibres are made of very high-quality materials but are highly contaminated (with rubber) and so are mainly buried as landfill or incinerated [ 21 , 22 ].

Feb 21, 2019  “Using waste materials in this way is less expensive, and better for the planet.” The fibres melt under the intense heat from a fire, leaving networks of tiny channels. This means that moisture trapped within the concrete is able to escape, rather than becoming trapped, which causes the concrete to break out explosively.

Disposal of Waste Tires EcoMENA

Mar 17, 2019  Disposal of Waste Tires. Tens of millions of tires are discarded across the Middle East every year. Disposal of waste tires is a challenging task because tires have a long life and are non-biodegradable. The traditional method of disposal of waste tires have been stockpiling or illegally dumping or landfilling, all of which are short-term solution.
