manufacture of reinforced concrete

Sustainability

The steel reinforcing bars used in reinforced concrete consist of nearly recycled material. More than 7 million tons of scrap steel is recycled into reinforcing bars every year, virtually the entire feedstock. This recycling avoids a massive energy expenditure — one ton of steel reinforcing bars would otherwise require about 2,500 pounds ...Web
