With this present work, the authors intend to outline the framework of the properties of calcined quarry dust (CQD) activated binders. Compressive strength, phase assembles, and the pore structure were investigated and compared with CaO activated binder. The research work has brought about a discovery that CQD activated binders presented higher compressive strength than CaO activated binders after long curing periods due to the formation of abundant hydrotalcite (Ht) like phases, although relative lower compressive strength was found. Besides, decreased Al content was observed in C-S-H when utilization of CQD acted as activator. Furthermore, all binders in the present work exhibited satisfactory mine tailings immobilization capacity although better performance was detected in CQD based binders.

通过这项当前的工作，作者打算概述煅烧的采石场粉尘（CQD）活化粘合剂的性能框架。研究抗压强度，相组装和孔结构，并与CaO活化的粘合剂进行比较。这项研究工作发现，尽管发现了相对较低的抗压强度，但由于形成了大量的水滑石（Ht）状相，CQD活化的粘合剂在长时间固化后比CaO活化的粘合剂具有更高的抗压强度。此外，当利用CQD作为活化剂时，CSH中的Al含量降低。此外，尽管在基于CQD的粘合剂中检测到更好的性能，但本工作中的所有粘合剂均表现出令人满意的矿山尾矿固定化能力。
