在工程实践中,水泥加固硫酸盐渍土易产生钙矾石晶体,导致水泥土膨胀破坏。六偏磷酸钠可在无杂质离子溶液环境下抑制钙矾石成核反应,然而在复杂硫酸盐水泥土环境中对钙矾石的抑制效果尚不清楚。借助扫描电镜(SEM)和X射线衍射(XRD)等测试方法,分析了不同六偏磷酸钠含量对不同硫酸盐环境(浸泡或内掺)水泥土中钙矾石晶体成核和生长的影响。结果表明:添加六偏磷酸钠不能有效抑制硫酸盐水泥土中钙矾石晶体的成核,但可以有效抑制钙矾石晶体的尺寸生长。
In practical engineering, sulfate-rich cement saline soil is prone to produce ettringite crystals, leading to the expansion and destruction of cement soil. Sodium hexametaphosphate can inhibit the nucleation reaction of ettringite in a solution environment without impurity ions. However, its inhibitory effect on ettringite in a complex sulfate cement soil environment is still unclear. In this article, the influence of different sodium hexametaphosphate content on the nucleation and growth of ettringite crystals in cement soil in different sulfate environments (soaked or incorporated) was analyzed by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that the addition of sodium hexametaphosphate cannot effectively inhibit the nucleation of ettringite crystals in sulfate-rich cement soil, but it can effectively inhibit the size growth of ettringite crystals.
