Due to the environmental benefits, the use of fly ash based concrete materials is rapidly increasing. The addition of fiber reinforcement has shown to greatly improve the properties of the material in similar ways as ordinary concrete. This high-performance fiber reinforced geopolymer composite (HPFR-GPC) has the potential of greatly impacting the environmental footprint and construction industry. The use of CNFs in HPFR-GPC also effects the self-sensing capabilities of the material. This experimental program aims to develop and characterize the mechanical and piezoresistivity of a new HPFR-GPC. This composite will consist of polyvinyl alcohol (PVA) microfibers, carbon nano-fibers (CNF), alkaline activators, silica sand, and an alumino silicate (Class F fly ash). This research explores the stress and strain values at first crack, last crack, and at maximum stress. Also, the elastic modulus, total fracture energy, and electrical conductivity under strain will be explored. Strains are obtained by strain gages and Digital Image Correlation (DIC) software, a large majority of strain readings are obtained by the DIC. This research program develops a mixing procedure that can be used by industry. Results show that increased mechanical and damage detection is capable and both the mechanical and electrical properties are subject to changing mix ratios. Overall, HPFR-GPC are proven to be a greener alternative than OPCC, have similar or better mechanical and electrical properties, applicable in industry, and costeffective.
