• [Display omitted] •Grits are used as aggregate in geopolymeric concretes for the first time.•Biomass fly ash are used as main alumina-silicate source (70 wt%).•Used industrial wastes are of biologic nature.•Manufacture is highly sustainable and reproducible.•Novel geopolymeric concretes are suitable for structural applications. This work investigates the production a green geopolymer-based concrete for a sustainable construction material using biomass wastes from a kraft pulp industry: fly ash (as main alumina-silicate source) and grits (as aggregate). Moreover, a simple, reproducible, ambient temperature, and low-cost manufacture is followed. Mix design aims to maximize wastes incorporation and optimize the mechanical performance. Preliminary tests indicate that the used wastes may be successfully employed to produce green geopolymeric concretes with satisfying mechanical performance (up to 18 MPa), according to the European standards. Furthermore, they represent a viable solution to reduce the environmental footprint associated with waste disposal.
