摘要:
无水石膏(CSA)作为一种资源丰富的固体废弃物,在工程建筑、家居装修及石膏砌块等领域具有广阔的应用前景,但其早期抗压强度发展缓慢及耐水性较差限制了其实际应用。通过机械力球磨及掺入硫酸钠、硫酸铝与生石灰化合物协同激发的方式对CSA进行改性,成功制备CSA基复合胶凝材料。利用扫描电子显微镜和X射线衍射表征CSA基复合胶凝材料的微观形貌及物相组成。研究表明:改性后CSA基胶凝材料的晶体形貌由原先破碎的块状转变为规整的短柱状结构。同时,其1 d与28 d抗压强度最高分别可达10.51、21.09 MPa,28 d软化系数达到0.88。机械力球磨与化学作用协同可有效诱导CSA发生晶格畸变,进而促进其水化进程,显著增强抗压强度并改善其耐水性能。
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.
