Today I present to you a new material qualified as ecological. The British company Novacem is working on a cement that considerably reduces the levels of carbon dioxide that are emitted into the atmosphere in the process of making this material.
This feature comes hand in hand with the materials they use for their manufacture. In particular, it consists of pulverized limestone, clay, sand and iron ore. As he explains Jorge Álvarez on your blog The Green Compass, this mixture is heated to 1.450 degrees with carbon or natural gas, producing, each metric ton, between 650 and 929 kilograms of carbon dioxide. This figure, calculated at an average of 2,8 million tons of cement per year, gives rise to 5% of the world's emissions in a year. Now, the process has changed since the limestone, rich in carbon, is discarded and, instead, the magnesium silicate is used, which does not require such high temperatures to harden, absorbing, in addition, the greenhouse gases.
According to Novacem, you can save up to 100 kilograms of gases in the production of each ton.
