CaliCrete^TM building panels can be made from Semidolime^TM binder and waste fillers such as ground car tyres or municipal waste. CaliCrete^TM can be cast into building products which are strong, light, fireproof, weatherproof and soundproof.

BUILDING PRODUCTS

This is similar to the first application, and the use of aeration technology would be the most likely to be used to give a high strength/weight ratio. The "aeration" is achieved with the CO₂ from the calcination process, which hardens the pores to provide added strength. The key steps are to optimise the recipes and to ensure that the binder is produced from dolomite resources worldwide. The testing process for this product encompasses the properties required by the building industry for similar products (eg Hebel cement). The product actually encapsulates 2/3 of the original CO₂ in the raw material.

QUICK DRYING CEMENT - Cheaper Cement with Half the CO₂ Emitted to Atmosphere (and 3 times the strength)

The "active" oxides of magnesium and calcium (lime) and dolomite (a mixture of the two) have very large binding powers compared to dead oxides produced under traditional calcining techniques. Hence clinker has to be added to lime and refired and reground to produce cement to give a satisfactory bind to sand or gravel.

If dolomite is flash calcined at medium temperature only the magnesium oxidises because the temperature is not great enough to make the carbonate give off its CO₂ to form calcium oxide.

The outcome is the product known as "dolime" which not only has a better performance than current cement product, but Calix expects will attract large carbon credits due it to emitting only one third of the CO₂.
