The addition sequence of raw materials during mixing is one factor that affects the fresh and hardened properties of ordinary Portland cement (OPC). Similar to OPC, the properties of alkali-activated materials (AAMs) may be susceptible to the mixing procedure, yet the mixing procedure's effect is still unclear. This research aims to investigate how different mixing procedures affect the fresh and hardened properties of the Na₂SiO₃-anhydrous alkali-activated materials along with polycarboxylate superplasticizer. Besides, a new mixing method named "hybrid-mixing" is proposed, evaluated, and compared with the conventional one-part (1 GP) and two-part (2 GP) mixing methods. It was found that the mixing procedure markedly affects the fresh and hardened properties of AAMs without changing their chemical composition. Compared with 1 GP and 2 GP binders, the hybrid-mixed binders achieved a relatively better slump-flow and compressive strength. The mechanisms governing different mixing methods are further discussed.

混合过程中原材料的添加顺序是影响普通波特兰水泥（OPC）的新鲜和硬化性能的一个因素。与OPC相似，碱活化材料（AAM）的特性可能会受到混合过程的影响，但混合过程的效果仍不清楚。这项研究旨在研究不同的混合程序如何影响Na ₂ SiO ₃的新鲜和硬化性能-无水碱活化材料以及聚羧酸盐高效减水剂。此外，提出了一种新的混合方法“混合混合”，并进行了评估，并与常规的单份（1 GP）和两份（2 GP）混合方法进行了比较。发现混合过程显着影响了AAM的新鲜和硬化性能，而没有改变其化学组成。与1 GP和2 GP粘合剂相比，杂化混合粘合剂具有相对更好的坍落度和抗压强度。进一步讨论了控制不同混合方法的机理。
