Gigacrete, which has no portland cement but a "proprietary non-toxic binder" made from "a different cementitious binder consisting of commonly found nontoxic elements available from many locations throughout the world."
Up to 80% of the volume of the material is fillers:These fillers include waste bottom ash from coal fired power generation stations, not just the marketable fly ash currently used in Portland-based concrete. Other potential filler materials that could be implemented include waste paper, recycled cardboard, recycled plastics, recycled polystyrene, agricultural waste fibers, and paper sludge.
All of the above materials become fireproof when mixed with the GigaCrete™ binder and can be made very lightweight with strengths close to, and even exceeding, traditional concrete. The new composites have virtually no shrinking or cracking like concrete and can be demolded within eight hours."
- Less carbon dioxide (CO2) emissions are produced from the
manufacture of the GigaCrete™ cement binder than compared to the
manufacture of Portland cement.
- Energy savings can be achieved with the GigaCrete™ PanelSystem due
to the high thermal efficiency and insulating value of the panel
material. According to the “Structural Insulated Panel Association in
Partnership with Oakridge National Labs,” structural paneled homes can
achieve energy savings of up to 70%.
- GigaCrete™ products use approximately two-thirds less water than conventional Portland-based cement products.
- High resistance to mold, mildew, insects, and vermin facilitates cleaner living environments.
- Reduction of waste materials is achieved due to efficient
manufacturing methods and a building system design that reduces
-All GigaCrete™ ash-based products are totally noncombustible and all GigaCrete™ sand-based products will not support flame - thereby reducing the potential for hazardous off-gases
associated with structure fires.
- Eco Friendly GigaFoam utilizes 100% waste ash as a filler material and is the only waste ash foam on the market.
