Article Synopsis
- - This study assessed different curing methods (water, sealed, standard, and open air) for PCBAs over 28 days to determine their impact on the production of phosphogypsum-based cold-bonded aggregates.
- - Results showed that water curing rapidly increased aggregate strength to 5.26 MPa within 7 days, while standard curing yielded a 19.3% improvement in strength after 28 days by enhancing hydration products and optimizing pore structure.
- - The research also noted effective solidification of phosphorus impurities across all curing methods, providing valuable insights for optimizing PCBA curing in industrial settings.
Current demand for waste recycling, phosphogypsum-based excess-sulphate slag cement (PESSC) as a sustainable cement prepared by solid wastes, urges enhancing its performance development based on microstructure optimisation. For the purpose of improving the performance and durability of PESSC used in normal or corrosive environments, it is deemed an efficient technique to produce iron-doped compounds with high thermodynamic stability. This paper presents a systematic study of the effect of iron modification on PESSC binders by introducing 0%-2% polyferric sulphate (PFS) from a multiscale viewpoint.
