本文从水化机理的角度,论述了应用复合外加剂(“LS-AC”)掺入硅酸盐水泥熟料中,制备低孔隙率波特兰水泥塑料(LPPC)、低温水泥(LTC)、油井水泥(OWC)和低热水泥(LHC)。与硅酸盐水泥(PC)相比,“木质磺酸盐-碳酸盐-熟料”体系的水化放热速率曲线具有三个放热峰和两个诱导期。第一诱导期的出现,给控制水化过程带来裨益,若改变水化放热速率曲线的形状就能够制备若干种特种水泥。 From the perspective of the hydration mechanism, this article discusses the use of composite admixtures (“LS-AC”) to incorporate Portland cement clinker to produce low-porosity Portland cement (LPPC) and low-temperature cement (LTC). ), Oil Well Cement (OWC) and Low Thermal Cement (LHC). Compared to portland cement (PC), the hydration rate curve of the “wood sulphonate-carbonate-clinker” system has three exothermic peaks and two induction periods. The emergence of the first induction period is beneficial for controlling the hydration process. If the shape of the hydration heat release rate curve is changed, a number of special cements can be prepared.
