Hybrid geopolymers represent a new class of composite materials formed by incorporating organic polymer into a geopolymer matrix. The properties of hybrid geopolymer depend on the addition of organic phase and the starting raw material composition (concentration of NaOH in alkaline activator, Si/Al mass ratio and solid/liquid mass ratio). In addition to these relevant parameters, this paper examines the synthesis conditions of these materials through the influence of the type, amount and manner of adding organic modifiers (commercial epoxy resins and 3- (methoxyl) propyl methacrylates) on forming the structure with significantly reduced pore distribution and decreased pore size, which exhibits good mechanical properties. The purpose of this research is to define the optimal conditions of the hybrid geopolymers' synthesis through the examination of relevant parameters. Expected improvement of mechanical properties was confirmed through values of compressive stength. Characterization of ...hybrid geopolymer composities was performed by XRD analysis, DRIFT spectroscopy and SEM analysis.
