This paper presents an experimental investigation on Steel Reinforced Grout (SRG) systems comprising multiple layers of galvanized UHTSS textiles, with either 4 or 8 cords/in density, embedded within a geopolymer mortar. Lap-splice tests and single-lap bond tests were performed to develop an improved understanding of the textile-to-textile load transfer capacity and of the SRG-to-concrete substrate bond behaviour. The effects of number of textile plies, cord density and compressive strength of concrete on the bond behaviour are analysed.
