Recent advancements in utilizing industrial waste materials as construction materials have elicited sustainable concrete production. Steel slags and Fly ash are some of the prime precursors used in geopolymer concrete. This research work aims to optimize the mix proportion of rock phosphate powder (RPP) with the combination of pozzolanic industrial byproducts (Fly ash, GGBS) as a precursor in the production of geopolymer concrete (GPC). The sodium hydroxide as an alkaline activator at a 10, 12 and 14 M concentration is used. In addition to using the materials mentioned above, M-sand and copper slag are used as the filler material to reduce depleting conventional river sand usage. An enormous amount of waste materials (fly ash, GGBS, and Copper slag) has been utilized in the study. The behavior of the concrete is evaluated for 7 and 28 days, along with the morphological analyses. The use of RPP favored the geopolymerization process and indicated a gradual increase in the strength properties. Through rigorous trials, the usage of RPP was affirmed with 30% replacement as source material with good mechanical strength and a workable slump. Increasing the molarity leads to a densely packed homogeneous matrix with low voids. From the results, RPP could be a precursor and potentially used with GGBS, fly ash to produce an ecofriendly GPC under ambient curing conditions.
