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.
