Geopolymers can be considered as inorganic polymers presenting good physicochemical properties.

Calcium carbonate powder is incorporated in a geopolymer formulation based on metakaolin. The rheological tests elaborated in different conditions allowed us to model their rheological behavior and follow the effect of carbonate introduction. Two models are observed, the Bingham model and the Herschel-Bulkley model. The introduction of calcium carbonates seems to have no effect on the evolution of the viscosity, while this latter has a remarkable sensitivity to the geopolymerization temperature.

Abstract
Geopolymers can be considered as inorganic polymers presenting good physicochemical properties. The principal advantage of these materials is their elaboration without a lot of energy spending compared to conventional materials. The choice of raw materials and the control of preparation conditions, represent important parameters controlling the rheological properties in the fresh state and physicochemical properties of consolidated geopolymers. Calcium carbonate powder is incorporated in a geopolymer formulation based on metakaolin. The rheological tests elaborated in different conditions allowed us to model their rheological behavior and follow the effect of carbonate introduction. Two models are observed, the Bingham model and the Herschel-Bulkley model. The introduction of calcium carbonates seems to have no effect on the evolution of the viscosity, while this latter has a remarkable sensitivity to the geopolymerization temperature.
