Marine species represent blueprints for stronger, more durable concrete

Sources: Massachusetts Institute of Technology, Cambridge; CP staff

In a project funded by outside parties and independent of the Concrete Sustainability Hub, MIT researchers are seeking to redesign concrete by following nature’s blueprints, contrasting cement paste with the structure and properties of bones, shells, and deep sea sponges. As they observe in a current Construction and Building Materials paper, such biological materials are exceptionally strong and durable, thanks in part to their precise assembly of structures at multiple length scales, from the molecular to the macro, or visible, level.
