Deep dives
Challenges in Making Construction More Sustainable
Concrete is responsible for 8% of global carbon emissions, making it essential to find sustainable solutions. Although using waste products from other industries is a step in the right direction, a more disruptive and long-lasting solution is needed. One challenge is the high maintenance and repair costs associated with concrete structures. By incorporating self-healing technologies, such as encapsulated healing agents, it is possible to decrease repair costs and indirect CO2 emissions. The goal is to create a future where self-healing concrete can reduce the need for excessive amounts of rebar and significantly decrease carbon emissions.
