AB Geopolymers are modern, amorphous inorganic aluminosilicate polymers with specific composition and properties. However, to use a geopolymer as an engineering material, its mechanical properties need to be improved. As part of this work, a composite material was obtained - the matrix is a geopolymer, and the reinforcement is basalt fibers. Research on the reinforcement of geopolymer material with layers of basalt fabrics was carried out in order to verify the improvement of mechanical properties in relation to non-reinforced material. Static and dynamic mechanical tests for the evaluation of flexural, compressive, splitting tensile and impact strength were carried out. In case of flexural strength the increase was even 150 % and in the case of impact strength over 60 %. The developed basel fabric reinforcement had a significant impact on the mechanical properties of the tested geopolymer composite material.
