摘要:

 以苹果酸为发泡硫氧镁水泥(FMOSC)改性剂,分析了其对FMOSC孔隙率、干密度、抗压强度、软化系数、干燥收缩率的影响,通过X射线衍射仪、红外光谱仪和扫描电子显微镜,研究苹果酸对FMOSC浆体的物相组成、断面微观形貌以及元素组成的影响。结果表明:苹果酸在基本不影响FMOSC的干密度和孔隙率前提下,抗压强度和软化系数为改性前的     2倍多,干燥收缩率显著降低;浆体性能和泡孔结构共同作用影响FMOSC的性能;苹果酸通过螯合作用抑制Mg(OH)2的生成,并促进生成大量517晶相,按照螺旋错位的方式生长。通过FMOSC孔径分布和泡孔微观形貌研究发现,苹果酸的添加使得泡孔孔径分布范围变窄,结构致密且在泡壁上生成大量517晶相。
