... Unique building from bacteria

 A bacterium that occurs naturally in soil, was revived in the mixed solution of urea and nutrients to maintain the temperature at 30 °. City of Madrid (Spain), is a hub of international scientists to participate in research and testing soon turn this idea into reality. According to Piero Tiano - Biologist Italian - said: "In this mixture of bacteria will begin to grow, basically they increase in number, they have reached a certain level it will turn liquid cement into one thick layer. After about 3 hours of fermentation, providing the ready to use ". Then, the scientists added to this solution a little microbes sand, cement industrial waste and grasshoppers. According to the researchers cement production industry generates about 5% of global carbon emissions. So with this project, the scientists believe can grow one type of cement friendly environment. Fermentation. Besides, Laura Sanchez Alonso - Project coordinator Green Eco-Cement Cement also said: "The additional raw materials are basically garbage, so we do not have to spend extra cost. For example, we do not have to purchase and transport of limestone - which is used to produce cement so we save energy costs. " In addition, the high temperature in production also means cost savings and reduce carbon emissions. In cement production process generally uses very high temperatures, ranging from 1,400 - 1.500oC to turn limestone into cement. With typical green cement, scientists only need to maintain 30 ° C for bacterial growth, proliferation. Initial tests for reliability, plasticizers and anti-deformation of new materials have shown promise. Currently the microbiology and chemistry are working to find ways to promote microbial activity more efficient as the ideal density of bacteria in the mixture. The researchers hope to cement this bacteria will be present in the European construction market in the shortest time possible.
