The XRD characterization of quarry dust showed sharp and intense reflections of the calcite phase (Figure 5 c). The sharp and narrow reflection of quartz was also observed at 2θ values of 27.1 and 50.5. Thus, the low reactivity of the quarry dust can be attributed to its low surface activity and larger dust particle sizes.
