They have developed a new type of concrete made from tire rubber, a sustainable solution that can reduce costs and preserve the environment.

Previously, rubber particles from tires had already been used as a substitute for stone fragments used in concrete, but the result did not meet construction standards.

This time, all aggregates were replaced by tires, maintaining their mechanical properties. The result was a concrete that was lighter, more sustainable, and cheaper to produce and transport.

According to Mohammad Island, one of the scientists involved, the molding process was the key to success.

The technique involves new molds that compress the rubber in order to improve its constructive properties. Jie Li, the study's co-author, highlights the importance of the discovery due to its economic and environmental benefits.

He states that "as much of concrete is made from gravel aggregates, replacing this with tire rubber significantly reduces the consumption of natural resources and offers an environmental solution for used tires.

"By 2030, it is estimated that around 1.2 billion tires will be discarded annually, making reusing this material essential for protecting the environment.
