Fig. 1: Experimental (black solid line) and modeled (red solid line) XRD patterns of, from top to bottom, bentonite, hydrotalcite, CEM III/C, and silica fume.

Intensity scale multiplied by 5 for the 25–80 °2θ interval as compared to the 5–25 °2θ interval for the hydrotalcite patterns. The gray solid line below bentonite and hydrotalcite patterns are the difference between experimental and modeled patterns.
