Geo-Blue Crete - Reducing Carbon-dioxide Footprint

Portland cement is the most common type of cement used worldwide and  is the biggest target for reducing the CO2 footprint of building materials. According to the World Business Council for Sustainable Development, cement manufacturing is alone responsible for 5% of global CO2 emissions. To make cement, manufacturers heat limestone in a kiln to 2,650 °F. The process eliminates chemically bound water molecules, releases CO2, and produces a marble-sized material called clinker, which is then ground to a fine powder. Gypsum is added, and the resulting cement is mixed with water, sand, and aggregates to produce concrete. The rehydration causes an exothermic chemical reaction that hardens the mix.

Builders all over the world have recently become aware of the significant carbon footprint of their most basic building supplies. Experts estimate that the manufacture of tra
ditional building materials is responsible for 10–12% of carbon dioxide emissions in the U.S., mainly because of the large amount of energy used to create them.

Geo-Blue Crete uses many of the same materials used in blends with traditional Portland cement. However, the major difference comes from the fact that Geo-Blue Crete isn’t produced with quarried limestone product. Limestone creates an excessive amount of CO2 by virtue of the fact that extreme heat is used to create the cement. Geo-Blue Crete uses a proprietary catalyst/binding agent that can allow the cement to be produced at ambient temperatures, from sub-tropical to below freezing, meaning that it takes 80 to 90% less energy to produce and dramatically lowers the CO2 released into the atmosphere.

Geo-Blue Crete is not only environment friendly and effectively reduces the carbon footprint but is also stronger, sustainable and affordable as compared to the traditional Portland Cement
