(a) X-ray diffraction patterns of CEMIIB-LL and slag. It is showed that cement contains calcite (△), C3S (○), and C2S (□) whereas the slag contains calcium aluminium oxide (▲), pyroxmangite (●), glaucochroite (■), iron oxide (★), calcium silicate (□), and calcium magnesium silicate (▽); (b) X-ray diffraction patterns of ultramarine and green colour: ultramarine contains ankerite (⋄), sodium aluminium silicate (◆), and magnesium calcite (); green colour is mainly chromium oxide whose peaks are identified by (×).
