What is green cement?
Cement is called green when it is just poured. It is "green" until it sets up and cures or dries. This will vary depending on conditions. Wet cement has a slight green cast to it that changes to gray when it dries.In addition to consuming considerable amounts of limestone, sand and energy, producing each ton of Portland cement releases one ton of carbon dioxide into the environment. One of the emerging concrete technologies for sustainable development is to use "green" materials for construction. The "green" materials are considered as materials that use less natural resource and energy and generate less CO2. They are durable and recyclable and require less maintenance.
