A little more on green cement
13 November 2009
Green World Crete, Florida, has invented a low carbon emission cementitous product called Geo-Green Crete, providing the construction industry with a high-performance and cost-effective green alternative to Ordinary Portland Cement.
Geo-Green Crete is formulated using post-industrial waste and naturally occurring aluminoscilicate materials. Portland Cement, on the other hand, is formed by the application of intense heat to limestone in large kilns, leading to the release of carbon dioxide and other noxious chemicals and heavy metals into the atmosphere.
The Green World Crete scientists have focused their attention on developing a non-limestone based cement which does not require the use of fossil fuel to heat large kilns. Instead, the Geo-Green Crete process combines post-industrial waste and naturally occurring alluminosilicate materials with a binding agent at ambient temperature, in order to produce a long lasting eco-friendly cementitious material.
Unlike the Portland cement process, the production of the Geo-Green Crete product results in a near zero carbon dioxide emission manufacturing process.
