Abstract This paper presents the investigation on the adoption of reaction powder concrete (RPC) concept in geopolymer concrete (GPC) technology to develop ultra high performance concrete (UHPC). Ultra high performance geopolymer concrete (UHPGPC) was developed by completely eliminating Portland cement (PC) with industrial by-products such as ground granulated blast furnace slag (GGBFS) and silica fume (SF) activated with sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) solution. The fresh (flow) and mechanical (compressive strength) properties of the mixes with varying replacement level of GGBFS with silica fume, river sand with quartz powder and the inclusion of steel fibres were investigated. The results infer that the inclusion of silica fume, quartz powder and steel fibres has a momentous role on the strength development of the UHPGPC mixes. Additionally, statistical analysis has been carried out by design of experiments using response surface methodology. The ecological parameters were also assessed with the aid of embodied energy and carbon dioxide emission and the results were compared. From the results, it has been inferred that the analytical results were well correlated with the experimental results and the ecological parameters were also less compared to the cement concrete mixes and terms it to be sustainable production.
