机械力-化学作用协同诱导无水石膏晶格畸变及性能研究
Mechano-chemically induced lattice distortion in calcium sulfate anhydrite for property enhancement
摘要
Abstract
Calcium sulfate anhydrite(CSA),an abundant solid waste,holds great promise for applications in construction,interior decoration,and gypsum block manufacturing.However,its practical application is hindered by its slow development of early compressive strength and poor water resistance.In this study,CSA was modified via mechanical ball milling combined with chemical activation using sodium sulfate,aluminum sulfate,and quicklime,successfully producing a CSA-based composite cementitious material.The microstructure and phase composition of the resulting material were characterized by scanning electron microscopy(SEM)and X-ray diffraction(XRD).Results showed that the modified CSA-based cementitious material exhibited a morphological transformation from irregular fragmented particles to well-defined short prismatic crystals.Consequently,its compressive strengths at 1 d and 28 d reached 10.51 MPa and 21.09 MPa,respectively,and its 28 d softening coefficient attained 0.88.The synergy of mechanical ball milling and chemical activation effectively induces lattice distortion in CSA,which accelerates its hydration process,thereby significantly enhancing its compressive strength and improving its water resistance.关键词
