In this paper, high strength ductile engineered geopolymer composite (EGC) is investigated. EGC is an environmentally friendly and more importantly it is bendable geopolymer with tensile strain-hardening behaviour which possesses enhanced mechanical properties compared to normal geopolymer concretes and ordinary Portland cement (OPC) concrete. Bond performance or the bond strength between the rebar and the EGC is the main study in this research as it is an important factor as it influences the structural load bearing capacity and failure modes of elements. The idea of casting and creating the best mix design is required in order to generate higher strength EGC cured in ambient temperature. On top of that, the mechanical property is also a part that was discussed in this research which includes the compressive strength. Hence, in this study, the compressive strength of ductile fibrous EGC cured in ambient temperature is investigated. Moreover, bond strength between EGC and rebar with various diameters was used as variables in experiments to examine the results leading to bonding strength using the pull-out test method and from the analysis of bond strength it was observed that the bond strength of EGC increases with the increase in rebar diameter. Other than that, the slip behaviour of the EGC specimens decreases with the increase of rebar diameter. Critical analysis was made and calculated to conclude this investigation. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2024.
