The requirement for environmentally friendly construction materials for sustainable development is nowadays an important issue and the geopolymer technology provides a good solution to replace, as binder, the ordinary cement materials for green building. Fly ash, an industrial by-product currently disposed of as waste, can be used as feedstock for geopolymers with an excellent greenness. In order to preserve the eco-friendly nature of the fly ash based geopolymer and enhance the mechanical properties that represent a weak point of the cementitious materials, limiting their application fields, a new fly ash based geopolymer composite was introduced. For this purpose, inorganic, organic and natural short fibers, i.e. E-glass, aramid and hemp respectively, were considered as reinforcement. The mechanical response of these composites under quasi-static and dynamic load conditions was investigated and compared to plain geopolymers, drawing the attention to the hemp reinforced ones, because of their low coast and eco-friendly nature. |
