Zigzags for greener construction: Design avoids concrete and steel waste

Concrete is the most widely used construction material in the world. Made from cement, water, sand and gravel, this relatively cheap mixture can be shaped as needed and withstand high forces in compression. Yet it performs poorly under tensile stress, requiring steel reinforcement, and excessive amounts of material are often used. This fuels climate change, since producing concrete and steel generates significant carbon emissions.
