Non-Sintered Wrap-Shell lightweight aggregates from dredged soils: Study of softening coefficients and water Absorption-Desorption behavior
Highlights Organosilica as WRs can improve softening coefficient of WSLAs. The performance of OSI-WSLAs was better compared to other application locations. The OSI-WSLAs retain absorption–desorption behavior. The OSI-WSLAs have better salt freezing resistance due to the lower mass loss rate.
Abstract Wrap-shell lightweight aggregates (WSLAs) are significantly weakened after water immersion, which limit their widespread application. In this study, WSLAs were fabricated by adding various water repellents (WRs), and the impact of WRs exerting into different position was also study. Results show that OSI-WSLAs (organosilica as WRs applying into the shell) exhibited superior performance in strength (11.21 MPa) and water adsorption (9.97%), thus providing a high softening coefficient (0.90). The study of microspecimens preparation and the mass growth rate demonstrated that OSI-WSLAs presents controllable water absorption–desorption behavior. In summary, the excellent softening coefficient and regulatable “water absorption–desorption behavior” of OSI-WSLAs further expand the practical application of WSLAs, and thus provide a valuable reference for the application of WSLAs in the field of construction and building materials.
