Abstract
The invention relates to a process of making a light weight, cementitious, three dimensional structure such as a building panel which includes the steps of measuring a quantity of water, measuring about 425 kilograms of cement, and between approximately 40 to 60 grams of ferric chloride in 40% solution by volume per approximately 278 liters of water, mixing the quantity of water, the cement and the ferric chloride, measuring between approximately 0.620 kilograms and 1.347 kilograms of substantially pure powdered aluminum, between approximately 0.230 kilograms and 0.710 kilograms of Hexafluorosilicate, between approximately 0.560 and 0.680 kilograms of calcium formate, and between approximately 4 and 8 kilograms of fiber, per approximately 278 liters of water, combining the mixture of the cement, the ferric chloride and the water with the powdered aluminum, the Hexafluorosilicate, the calcium formate and the fiber, mixing the combination, waiting until the mixed combination rises, and forming the lightweight, cementitious, three dimensional structure.
