The d060 reflection is a determining signal to identify the structure of the smectite. In the case of the raw bentonite, the d060 reflection peak appears at 2θ (°) = 61.91, which supposes a distance of 1.49 Å. This value is typical of dioctahedral smectites, confirming that the main crystallographic phase is montmorillonite [ 32 ].

Sand casting involves several steps, including patternmaking, molding, melting and pouring, and cleaning. The pattern is the form around which the sand is packed, usually in two parts, the cope and the drag. After the sand is compacted enough to replicate the pattern, the cope is removed and the pattern extracted.

In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
