The production of low energy cements

Rising levels of ‘greenhouse’ gases in the atmosphere, and the associated increase in temperature of the environment are potentially able to alter the ability of the planet to support present life forms. These greenhouse gases are characterised by showing radiation absorption bands in the infrared region of the spectrum; examples are carbon dioxide, methane, ozone, NO_x and chlorofluorocarbons. The most important greenhouse gas is carbon dioxide-due to the volume produced. While there are still some who question the validity of the accepted mechanism of global warming, most of the scientific community find that greenhouse gases result in an increased temperature for the Earth’s troposphere.
