It is a common phenomenon for the traditional concrete to crack, requiring maintenance and reparations before reinforcement starts to corrode. Luckily, it seems that Delft University microbiology professor Henk Jonkers has found the solution to this problem. Inspired by nature, he developed ‘Bio-concrete’, a new type of material that brings together biology and civil engineering and could save billions in construction costs by improving the lifespan of buildings, bridges and roads. "It is combining nature with construction materials. Nature is supplying us a lot of functionality for free - in this case, limestone-producing bacteria’’, says the professor.
Broad Sustainable Building, a construction company in China, recently built a 57-floor, 2-million-square-foot skyscraper in just 19 days. That is an average of three floors per day. The building has 19 10-meter-tall atriums, enough office space for 4000 people and 800 apartments. The structure is made up of prefabricated sections that reduced the use of concrete by 15,000 trucks, which translates into less dust released into the air.
