Rubber Concrete

An innovative material, rubber concrete, is gaining traction in the market by blending concrete with recycled tyres. Although this composite may seem like an unlikely pairing due to the disparity in their inherent properties, it is being actively developed through various international initiatives, offering concrete a range of new and desirable characteristics. Recycled rubber from tyres presents several advantages for this innovative material. Unlike traditional concrete, rubber provides insulation, which enhances its thermal properties. Additionally, it is lightweight and resilient, with up to 2% elasticity. This unique combination of attributes makes rubber concrete effective at drainage, sound dampening, shock absorption, and vibration attenuation. Notably, it maintains comparable compressive strength to traditional concrete while also providing the added benefits of water absorption and drainage capabilities. The lightweight nature of rubber concrete not only reduces environmental impacts during transportation and handling but also conserves materials. Processed forms of worn-out tyres, such as graunlate and fine shreds (less than 25 mm), are seamlessly integrated into the mixture, enhancing sustainability while minimizing waste. The rubber concrete may also be recycled again through crushing and mixing into new blends.
