Spanish scientists develop a new environmentally friendly cement
A team of Spanish scientists from the ‘Consejo Superior de Investigaciones Científicas’ (CSIC) have developed a new type of cement which could reduce carbon emissions from the cement industry by up to 50%. This new type of cement is produced using much lower temperatures than those normally used in cement production.
Ángel Palomo, the scientist leading the research team for CSIC will be presenting his findings to the European Consortium for Research into new materials within the next few days.
Palomo, explained that normally cement is produced at a temperature of 1450 degrees centigrade but that the new type of cement could be produced at between 60 to 80 degrees centigrade. He added that this difference could greatly reduce carbon dioxide emissions from the cement industry and reduce energy consumption in the production of cement by up to 50%.
Another important advantage of this new type of cement is that it uses ash from burnt coal which is an abundant industrial by-product in the whole world.
Furthermore if not reused it is also a contaminant.
The new cement has been submitted to various tests and results so far have shown that the it is equivalent to the cement currently being used and in fact it is better in some ways according to Palomo.
