The incorporation of different levels of UOW into Portland clinker raw meals and its effects on the clinker and cement properties were evaluated. Clinkers were produced and characterized by X-ray diffractometry (XRD) and optical microscopy; the cements were produced and physically characterized. Finally, pastes were produced and analyzed using isot...

... process of TiO 2 production and generation of unreacted ore (UOW) are displayed in Fig. 1. UOW was generated and supplied by Tronox Pigmentos do Brasil S.A. and collected according to the waste sampling procedure specified in Brazilian standard NBR 10007 [26]. UOW is generated from the processing of a mixture of ilmenite (FeO. TiO 2 ) and titanium slag to produce the TiO 2 pigment. In this process, this mixture goes through ...

... . S1 shows the X-ray patterns of the pastes of the different cements studied at 3, 28 and 63 days. In all pastes, diffractometric peaks corresponding to the anhydrous phases (alite and belite) were identified, indicating that, as expected, up to 63 days, none of the cements was fully hydrated. In addition, for all evaluated pastes, the ...

... The formation of the alite and ferrite phase was more in EAF containing clinker than BOF which may be attributed to the alkaline and impurities content in both slags. Impurities oxides (such as vanadium) are known to affect the burnability of clinkers while some (such as titanium, copper) act as mineralizer or fluxing agent during clinkering, reducing the mineralogy formation temperature and thereby increasing alite and ferrite phases [4][5][6]. These mineralogy variations are evident in the strength result of the paste samples in Fig.1. ...
