We recently reported the first comprehensive investigation of magnesium potassium phosphate cements (MKPCs) blended with supplementary cementitious materials (pulverized fuel ash and granulated blast furnace slag) for the encapsulation of radioactive wastes [Gardner et al., Cem. Concr. Res. 74 (2015) 78–87]. Using a combination of characterization techniques, we demonstrated the important role of the reaction of the supplementary cementitious materials in contributing to the development of the microstructure and strength of MKPC composites. Here, we clarify aspects of our experimental design, and elaborate on the interpretation of our data, following discussion by Ma and Li.

回应马红艳、李英《粉煤灰粉煤灰高炉矿渣粉混合磷酸钾镁水泥的特性》一文的讨论

我们最近报道了首次对磷酸镁钾水泥 (MKPC) 与补充胶结材料（粉状燃料灰和粒状高炉矿渣）混合用于封装放射性废物的综合研究 [Gardner 等人，Cem。康克。水库 74 (2015) 78-87]。使用表征技术的组合，我们证明了补充胶凝材料的反应在促进 MKPC 复合材料的微观结构和强度的发展中的重要作用。在这里，在 Ma 和 Li 的讨论之后，我们澄清了我们实验设计的各个方面，并详细说明了我们数据的解释。
