			*This Page goes over Geopolymers, a type of material based off of soil that has been cleared and leveled, then a polymer agent (Typically a liquid) is applied making it into a [[Composite Material]]
			*Used mainly as either a road surface ( [[Geopolymer Road]] ), or as a surface treatment to reduce dust at a facility without using pavement (Typicaly for temporary facilities)
			*Can also be used to make [[Stablalized CEBs]]

	Some have described geopolymer as a man-made zeolite; some as man-made limestone. It could also be likened to a man-made soil duripan, especially if volcanic ash is used as a amorphous silica source. Clearly, a range of local natural earth materials can be successfully used, but a period of formula testing is necessary.

	Geopolymerization is the process of polymerizing silica and alumina containing minerals using alkali solvents. Discovered (or ''re''discovered) by Joseph Davidovits in France, geopolymer cements are likely similar to materials used in antiquity. Although cements are the most common application of geopolymerization, a range of refractory and structural products have been produced. The products of geopolymerization are called poly-silicates.

	The vast majority of minerals on the earth's surface exist as alumino-silicate crystals (for example: clays, feldspars, quartz). By dissolving these and then allowing them to recondense, materials with longer range crystalline structure than its components may be formed.
