 It was recently estimated by The New York Times that every year, one cubic yard of concrete is produced for each person on the planet. It’s easy to realise, in terms of scale, why concrete production is responsible for five percent of the world’s carbon emissions. But there are chemical reasons why concrete is so environmentally damaging, and why Professor Pal Mangat of Sheffield Hallam University’s Materials and Research Institute, has developed a more climate-friendly material called Liquid Granite.
‘Conventional concrete was a material that was developed quite some time ago,’ says Professor Mangat, ‘and at the time, the environmental concerns weren’t understood. Now we are aware of carbon footprints, and that the emission of carbon dioxide is a serious problem, and cement unfortunately steps on both of them.’ Liquid Granite is made from between 30 and 70 percent recycled material. But there are other major advantages of Liquid Granite.
