研究锗废渣掺入水泥及膏体后对其水化凝结规律的影响。将锗废渣以不同比例掺入水泥,经研究发现锗废渣不同掺量可以对水泥水化凝结起到调节作用。在此基础上,将尾砂和锗废渣以不同比例配制成膏体,发现锗废渣对膏体凝结起到了促凝的作用,而且掺量越大,效果越明显。经分析认为,锗废渣的掺入使水化反应生成更多的钙矾石,从而降低尾砂中Zn2+对膏体的缓凝作用。这为进一步研究将锗废渣掺入膏体调节膏体凝结时间提供理论依据。
The hydraulic condensing rules after the cement and paste mixed with germanium waste were studied. Firstly different proportions of germanium waste mixed with cement were used, then it was found that different proportions of germanium waste can be regulatory role on hydraulic condensation. On the basis of the current industrial parameters, according to the different proportions of tailings and germanium waste made into paste, it is found that the germanium waste plays a promoting function of condensation, and the greater the mixed quantity, the greater the effect is. Experiment shows that with the germanium adding to paste with more ettringite to generate Zn2+ is reduced within tailing to paste of the slow effect. This provides the theory basis adjust setting time for paste which is mixed with germanium waste.
