The underwater coral reefs of the world are in grave danger. Due to pollution, climate change, and other negative factors, these diverse and fascinating ecosystems are facing extinction. It is estimated that 90% of Earth’s coral will die out by 2050. However, scientists and researchers are not sitting idly by. Efforts are underway around the world to provide the oceans with 3D printed coral reefs, in hopes of preserving their biodiversity.
In recent years, several exciting technologies have emerged in the field of coral preservation. From growing natural coral on 3D printed structures to fish preservation, various materials and 3D printing technologies have been employed. Now, a multidisciplinary team from the University of Texas at Arlington is embarking on their own coral preservation project in the Gulf of Mexico.
One of the challenges faced in previous efforts at artificial reef creation is the choice of materials used to create a safe area for ocean wildlife to thrive. In the early stages of this process, a wide range of objects were used, from decommissioned ships and scrap metal to rubber tires and concrete blocks. However, these materials posed risks of breaking apart or further polluting the environment due to the shifting currents and underwater wear and tear.
To address this issue, the UTA team, led by Warda Ashraf, an associate professor in the Department of Civil Engineering, plans to use a 3D printing material similar to ancient Roman concrete. Roman concrete, while appearing similar to modern construction material, has several key differences that make it stronger and more durable. It is mixed with various rocks, large pieces of stone or rubble, and volcanic dust or ash, which create reactions when mixed with seawater. This results in a substance that is more resistant to cracks and breaks. In fact, Roman concrete continues to harden and strengthen for years, or even decades, after construction, making it one of the most durable building materials in human history.
It is these underwater characteristics of Roman concrete that interest Ashraf and her team. The saltwater-resistant material could potentially provide a long-lasting solution for repairing and rebuilding coral reefs. Furthermore, it poses less of a risk for environmental pollution compared to modern concrete or other solutions.
The team has already conducted successful tests by 3D printing small pieces of Roman concrete and submerging them underwater in Baffin Bay, a small inlet off the Gulf of Mexico. Barnacles have attached themselves to the new reef, demonstrating that the materials provide a suitable habitat for marine life. Additionally, the concrete has shown an increase in strength of 40% to 50% in seawater within just five months.
Interestingly, the Roman concrete used in this project carries the added bonus of being capable of capturing carbon dioxide, much like real coral does to build its skeleton. As a result, the Roman concrete coral reefs could potentially sequester thousands of tons of carbon under the ocean, offering coastal resilience and supporting marine habitat.
With a team of professionals and a $2 million grant from the National Science Foundation, Ashraf and her team are determined to make a significant impact on preserving marine biodiversity worldwide. The project not only aims to repair and rebuild coral reefs but also seeks to address carbon sequestration and coastal resilience.
