Geopolymer is a term originally coined by French researcher Joseph Davidovits to describe a class of cement formed from aluminosilicates. Traditional portland cement relies on the hydration of calcium silicates, but geopolymers form by the condensation of aluminosilicates. The kinetics and thermodynamics of geopolymer networks are driven by covalent bond formation between tetravalent silicon and trivalent aluminum. The molar ratio of these key components along with sodium, potassium, and calcium have been shown to affect set-time, compressive strength, bond strength, shrinkage and other desired properties. 
 
In various parts of the world, this type of material is also industrially known as alkali-activated cement or inorganic polymer concrete. Geopolymers are known to provide comparable or better performance to traditional cementitious binders but with the added advantages of significantly reduced greenhouse emissions, increased fire and chemical resistance and reduced water utilization. 
No.  When you see the term geopolymer for the first time, you might assume the material will be a plastic, like HDPE or polyester. While it is true that plastics are polymers, not all polymers are plastics. So instead of thinking of the materials you find that make up plastic bottles or food storage containers, you should imagine a material that behaves like cement.

Our GeoSpray® geopolymer mortar has the look and feel of most standard cements—its geopolymer powder containing pozzolans is mixed directly with water to form a mortar just like standard cement materials. GeoSpray mortar has been specially formulated for centrifugal casting of large diameter pipes, but its processability and workability are like what you might expect from a cement mortar.  

You can think of GeoSpray mortar as an “advanced cement.” Compressive, tensile and flexural properties of GeoSpray mortar have been engineered to meet or exceed the properties you would expect from a cement formulation.

The major advantage of a geopolymer over typical cement mortars is that a geopolymer has the chemistry of an engineered stone. The aluminosilicate network that forms the chemical structure of GeoSpray is like the chemical structure found in natural stones, such as zeolites or quartz. 

This stone-like chemistry is different from the hydration chemistry that is present in standard portland and calcium aluminate cements, which creates a distinct advantage in chemical resistance. Additionally, unlike standard cement mortars, GeoSpray mortar continues to react with itself for decades, building additional strength and enhancing its service life expectancy.
