The proper control of the rheological performance of silicate-based alkali-activated slag (AAS) mixtures is problematic, as the conventional superplasticizers become less effective in alkaline media. Nevertheless, several methods have been proposed to improve the workability of silicate-activated AAS, such as by extending the mixing time, and replacing sodium silicate with sodium carbonate activators. However, the underlying fluidizing mechanism is not yet well understood in the literature, which is crucial knowledge to achieve proper rheology control of silicate-activated AAS.

搅拌条件和阴离子活化剂对硅酸盐活化矿渣混凝土流变性能的影响

硅酸盐基碱激活矿渣（AAS）混合物的流变性能的适当控制是有问题的，因为传统的超增塑剂在碱性介质中变得不太有效。尽管如此，已经提出了几种方法来提高硅酸盐活化AAS的可加工性，例如通过延长混合时间，以及用碳酸钠活化剂代替硅酸钠。然而，文献中尚未充分理解潜在的流化机制，这是实现硅酸盐活化 AAS 适当流变控制的关键知识。
