摘要
用XRD层析技术和SEM等手段测定了石灰石集料-硬化硫铝酸盐水泥浆体界面区的组成与结构;用XRD线宽法测定了界面区中AFt的晶体尺寸及其分布。结果表明,界面区的厚度为50μm左右;在石灰石界面区中,AFt晶体和C(?)H_2晶体发生富集,且AFt晶体尺寸较粗大。同时探讨了界面区微结构的形成机理。
The composition, structure and morphology of interfacial zone between hardened sulphoaluminate cement paste (HSCP) and limestone aggregate are investigated with XRD and SEM technique. The results show that the thickness of interfacial zone between HSCP and limestone is about 50μm. AFt and C(?)H_2 crystals contents and AFt crystal size decrease as the distance from limestone surface increases. According to the study of the composition and structure of interracial zone, the forming mechanism of the structures is discussed.
