Australia engineers produce concrete from tyre, rubber and rocks

The study published in the Resources, Conservation & Recycling journal showed the tyres’ manufacturing process.

Lead author and Ph.D. researcher from RMIT University’s School of Engineering, Mohammad Momeen Ul Islam, stated that this work was revolutionary because it showed what could be done with recycled rubber pieces.

“We have demonstrated with our precise casting method that this decades-old perceived limitation on using large amounts of coarse rubber particles in concrete can now be overcome,” Islam said.

“The technique involves using newly designed casting moulds to compress the coarse rubber aggregate in fresh concrete that enhances the building material’s performance,” he added.

This advance builds on the breakthrough invention of this technique by fellow RMIT University Engineers Professor Yufei Wu, Dr. Syed Kazmi, Dr. Muhammad Munir, and Shenzhen University’s Professor Yingwu Zhou.

Cheaper materials, eco-friendly products

Study co-author and team leader, Professor Jie Li, stated that this production process will greatly benefit the environment and the economy.

“The greener and lighter concrete could also greatly reduce manufacturing and transportation costs,” Li said.

“This would benefit a range of developments including low-cost housing projects in rural and remote parts of Australia and other countries around the world.”

“As a major portion of typical concrete is coarse aggregate, replacing all of this with used tire rubber can significantly reduce the consumption of natural resources and also address the major environmental challenge of what to do with used tyres,” Prof. Li shared his thoughts.
