Processes and methods of making and preparing, compositions and structural products therefrom are provided, whereby the surface area of alumino-silicate based powders is greatly increased and rendered chemically active so that when the functionalized powders are mixed with water poly-condensation reactions occur between the surfaces binding the powders together to form a structural material with negligible emission of carbon compounds. In another embodiment, the surface functionalized powders can be mixed with an additive; a dry aggregate, such as sand and water to make a slurry that can be poured or cast into any desired shape and rapidly cured to a hardened shape suitable for use as a structural material with the mechanical strength equivalent to Portland-cement based concrete products. In additional embodiments, the alumino-silicate based powders are nano-functionalized and foam functionalized to provide light weight and structurally strong materials that can also be used in combination with or as replacement for Portland-cement.

Structural materials with nearly zero carbon emissions

A method for depositing sol-gel derived coatings on substrates to form coated substrates includes the steps of providing a first solution including at least one sol precursor and at least one solvent. A water comprising solution is added to the first solution to form a sol-gel. The sol-gel is deposited on a substrate. The sol-gel layer on the substrate is dried/cured at a temperature &#x2266;100&#xb0; C. for at least 10 minutes to form a solid layer, wherein the solid layer has a thickness from 50 nm to 110 nm. The depositing and curing steps are repeated at least once until combined thickness of the solid layers forms a coating of a predetermined thickness. The resulting solid layers are low water content layers that can be evidenced by transmission measurements. The coated substrate can be an IR transmissive substrate having a recrystallization temperature &#x3c;130&#xb0; C. and each of the solid layers provide a transmission at &#x3bb;=2950 nm, normal incidence and 1 mW power if placed on the IR transmissive substrate of &#x2267;99% of the transmission directly through the IR transmissive substrate.
