This study compared the physical properties and mechanical strength development of PCBAs with water, sealed, standard, open ambient air curing over 28 days to find a suitable method for production phosphogypsum-based cold-bonded aggregates. The types relative amounts hydration products, microstructural morphology pore structure parameters were characterized utilizing XRD, TGA, FTIR, SEM nitrogen adsorption methods. According results, water leads rapid increases in single aggregate strength, reaching 5.26 MPa at 7 d. standard condition improved d aggregates by 19.3% others promoting generation products transformation C-S-H gel higher degree polymerization optimizing structure. Further, achieved an excellent solidification phosphorus impurities under all four conditions. work provides significant guidance selecting optimized PCBA industrial production.

Sulfate dry-wet cycle erosion significantly affects the mechanical properties of concrete. Investigating uniaxial compressive stress-strain relationship under these conditions is essential for developing accurate constitutive models. This study analyzes curves concrete subjected to cycles in 5% and 15% sulfate solutions. The results show that initial compaction phase particularly pronounced increasing concentrations counts. experiences an extended phase, which accounts up 35.71% total strain process. finding challenge traditional models, struggle accurately describe this phase. To address issue, develops a nonlinear model concrete, incorporating damage caused by erosion, based on Weibull statistical mechanics principles. research indicates effects concentration count are predominantly reflected nonlinearity skeleton function's opening size (a) shape characteristics (b), modeled using fourth-degree polynomial. demonstrates excellent fit experimental data with R2 value 0.99989, showing proposed effectively captures behavior provides robust framework models such environments.
