The comprehensive utilization of phosphogypsum, phosphorus tailings, and blast-furnace slag is of great significance to environmental protection, resource conservation, and economic development. This study utilized phosphogypsum-blast furnace slag cold-bonded aggregate (PBCA) as the aggregate
β-hemihydrate phosphogypsum (β-HPG), blast furnace slag (BS), and phosphate tailings (PT) as raw materials
along with polycarboxylate superplasticizer (PS) and vinyl acetate-ethylene copolymer re-dispersible latex powder (EVA) as admixtures to produce phosphogypsum-blast furnace slag-phosphorus tailings unburned bricks (PBPB). The mechanical properties of the unburned bricks were optimized through single-factor experiments. Ca(OH)
