Cement is one of the most crucial materials in modern construction industry. It works as the binding material, which keeps other materials such as bricks, steel together intact. Green cement is a relatively new concept yet it has been used widely in the construction industry. As an initiative to reduce environmental threats produced by manufacturing of cement, green cement has opted for construction. Green cement is a form of cement, which is produced with the help of a carbon-negative manufacturing process. It means harmful emissions during the manufacturing of cement are minimized, making that cement eco-friendly. Green cement offers various advantages over ordinary Portland cement. For instance, it reduces carbon dioxide emissions by up to 10%, it reduces water consumption by 20 percent.
