Background Phosphogypsum is a waste by-product during the production of phosphoric acid. It not only occupies landfill, but also pollutes the environment, which becomes an important factor restricting the sustainable development of the phosphate fertilizer industry. Research into cast-in-situ phosphogypsum will greatly promote the comprehensive utilization of stored phosphogypsum. The aim of this study was to clarify the mechanical properties of phosphogypsum. Methods Stress-strain relationships of cast-in-situ phosphogypsum were investigated through axial compressive experiments, and seismic performance of cast-in-situ phosphogypsum walls and aerated-concrete masonry walls were simulated based on the experimental results and using finite element analysis. Results The results showed that the stress-strain relationship fitted into a polynomial equation. Moreover, the displacement ductility index and the energy dissipation index of cast-in-situ phosphogypsum wall were 6.587 and 3.425, respectively. Conclusions The stress-strain relationship for earthquake-resistant performance of cast-in-situ phosphogypsum walls is better than that of aerated-concrete masonry walls. The curve of stress-strain relationship and the evaluation of earthquake-resistant performance provide theoretical support for the application of cast-in-situ phosphogypsum in building walls.

Abstract This paper presents a research of influence of horizontal reinforcement on compressive and shear strength of Autoclaved Aerated Concrete (AAC) masonry. Specimens were tested according to guidelines of EN 1052-1 and ASTM ES519-81 code in case of compression and shear test respectively. Reinforcement in the form of strips of mesh rolled out from a roll, consists of steel cords with an interwoven fiberglass roving was used. The influence of this type of reinforcement was also compared with the results of tests of AAC masonry walls without reinforcement, reinforced with truss type reinforcement and reinforced with synthetic mesh respectively.
