    Abstract

  • Abstract

    With the rapid reutilization of solid waste materials, it is imperative to investigate the properties of composite materials formed by the addition of solid waste materials. Basic foamed magnesium oxysulfate cementitious material(FMOCM) with and without solid waste materials were studied and compared. This study focused on the internal structures and quasi-static and dynamic mechanical properties of FMOCM. The results showed that the internal cavity structure of the FMOCM underwent significant changes, and the pore sizes became smaller owing to the addition of recycled materials and wood flour, which greatly improved the quasi-static strength of the FMOCM. It was found that the FMOCM had obvious strain rate effects. By comparing the dynamic strength factors, the dynamic strength of the regular FMOCM almost doubled, and the addition of solid waste materials weakened the strain rate effect. Only when the strain rate was lower did the FMOCM with solid waste materials show better toughness compared to the more serious fracture of the regular FMOCM. Furthermore, this study demonstrated the broad application prospects of solid waste materials in magnesium oxysulfide cementitious materials.

    • Public Summary

    • The internal cavity pore sizes became smaller owing to the addition of recycled materials.
    • The quasi-static strength of the FMOCM was improved, but the strain rate effect was weakened.
    • The FMOCM with solid waste materials show better toughness.
