Scientists have developed an innovative concrete that consists of rubber from used tires, rather than traditional aggregates such as gravel or rock fragments. This solution is completely efficient and ecological.
Our results refute the popular theory about what can be achieved with recycled rubber particles in concrete. We have shown that this limitation, envisioned by decades of using large amounts of coarse rubber particles in concrete, can now be overcome. This technology involves the use of newly designed molds to compact the coarse rubber aggregate into fresh concrete, increasing the performance of the building material.Muhammed Muminul Islam of RMIT University, lead author of the study
How was innovative concrete created?
Innovative concrete is based on a technology developed by the professor. Yufei Wu of RMIT University and Professor. Yingwu Zhou of Shenzhen University. The new production process will unlock environmental and economic benefits. Several patents are currently pending to further protect this technology.
Since a large part of typical concrete is coarse aggregate, replacing it entirely with rubber from used tires can significantly reduce the consumption of natural resources as well as solve the major environmental challenge of what to do with used tires.a. Ji Lee from RMIT
Statistics show that around 1.2 billion waste tires will be disposed of annually worldwide by 2030. Greener and lighter concrete can significantly reduce manufacturing and operating costs of transportation.
This will be useful for a range of development projects, including low-cost housing projects in rural and remote areas of Australia and other countries around the world.a. Ji Li
The technological process can be easily scaled up, allowing to create precast concrete elements anywhere in the world. After successful testing, scientists at RMIT now plan to test how they perform in structural elements.
