Over the past year, the topic of rare earths has been constantly in the news for their geopolitical and domestic importance to the future of technology, the economy, and defense. They influence war strategy in Europe and trade policy in Asia. The US and the world need these materials for cell phones, electric cars, computers, energy, space exploration, and countless other uses.
For those of us in the mining industry none of this is new. Yet mention “mining” and public reaction is not one that generally associates the products or the people with innovation, high tech, or advanced education. Quite the opposite.
The reaction is similar for aggregates and concrete. Ask anyone how these products are used and the answers might mention construction of buildings, roads, bridges, foundations, homes and every instance of infrastructure imaginable. Such uses are innumerable and indispensable to our civilization but don’t usually register in the realm of renowned technology.
For example, there are advancements in concrete technology that are revolutionizing the industry and are either in use already or underway. One of the latest developments is that concrete may soon be used as an energy storage system. By combining cement with other ingredients, including electrolytes, concrete can make walls, sidewalks and other structures store and release electrical energy so that concrete doubles as a giant “battery”.
Between energy storage, carbon sequestration, and self healing, sustainability now means that concrete is multifunctional. Imagine roads that can charge electric vehicles or eliminate salting, and homes and buildings that power themselves off the grid.
This is only one example of many that makes mining a leader in next world technologies.
