本文研究了用逐级增加TiO_2含量(TiO_2以当量取代SiO_2、Al_2O_3和Fe_2O_3)制成熟料相C_3S、C_2S、C_3A、C_2F和C_4AF的变体,密度和颜色的变化,确定了TiO_2的结合极限,得出了在结合极限以上形成的新化合物,并研究了水硬性能(强度和水化热的发展)。其主要结果综合在表6中。由这些结果可以推知,当采用高的标准石灰率和硅率时,水泥强度的发展,可以得到最显著的改善。例如,当标准石灰率为100、硅率为3.0,铝氧率为1.5时,早期强度可以提高20%以上,晚期强度大约可以提高10%。 标准石灰率(KST)=100CaO/(2.8SiO_2+1.1Al_2O_3+0.7Fe_2O_3)—译者。
In this paper, the variation of the morphologies, C3S, C_2S, C_3A, C_2F, C_4AF, C_3S, C_2F, and C_4AF, the density, and the color change of the TiO_2 content (TiO_2 equivalents in place of SiO_2, Al_2O_3, and Fe_2O_3) were studied to determine the binding limit of TiO_2. A new compound formed above the bound limit was derived and hydraulic properties (strength and development of hydration heat) were investigated. The main results are summarized in Table 6. From these results, it can be inferred that when high standard lime and silicon rates are used, the development of cement strength can be most significantly improved. For example, when the standard lime ratio is 100, the silicon ratio is 3.0, and the aluminum oxygen ratio is 1.5, the early strength can be increased by more than 20%, and the late strength can be increased by about 10%. The standard lime ratio (KST) = 100CaO/(2.8SiO2 + 1.1Al_2O_3 + 0.7Fe_2O_3) - translator.
