The aim of the present work has been the synthesis of geopolymer composites consisting of a geoplolymer matrix, obtained by alkali activation of metakaolin, and different percentage of polyethylene glycol (PEG). The obtained composites were analyzed by Fourier transform infrared spectroscopy and scanning electron microscope in order to identify the interaction formed between the organic and the inorganic component and to investigate materials microstructure. Further, the mechanical properties of the composites were studied by traction and bending tests.
