Abstract
It has been found that the addition of certain components, despite their low concentration in raw mix, may accelerate and enhance the reactivity of the cement raw mix. The utilization of mineralizers to facilitate and quicken the process of clinkerization backpedals numerous years, the concept of using such mineralizers to burn normal raw mixes at a much lower temperature with the end goal of decreasing the fuel necessities of the furnace and to enhance the cement proprieties has become to be seriously considered over the most recent couple of years.The subject of this paper is to investigate the impact of calcium fluoride as mineralizer on addition during the clinkerization process of industrial raw mixtures and its effect on chemical, mineralogical, and mechanical properties of CPA Moroccan cement. Five different raw meals were utilized and were burned with 2% of calcium fluoride. The resulting clinker was analyzed by X-ray diffraction (XRD) and fluorescence spectroscopy to determine the chemical phases of the obtained clinker, and the mechanical properties of resulting CPA cement were determined. The results show that the addition of 2% of CaF2to the clinker raw meal induced a decrease in the burning temperature and free lime, while improving the clinker phase formation and the mechanical properties of obtained cement.
Highlights
In the recent years many studies have concentrated on the investigation of processing production of clinkers at the lowest temperature than those regularly experienced, while in the meantime producing a better quality product that fulfills Requirements of various standards
They majorly affect the determination of the burning zone and the clinker compound formation, they can facilitate and quick the clinkerization process, by decreasing the liquid phase temperature and mineral fusible eutectic in the aim of saving the clinker production energy and improving the cement compound reactivity [2, 3]
The aim of this work was to examine the impact of calcium fluoride mineralizer (CaF2) on the decreasing temperature of burning of Moroccan industrial raw mixtures, and to study it effect on chemical, mineralogical, and mechanical properties of the clinker cement
Summary
In the recent years many studies have concentrated on the investigation of processing production of clinkers at the lowest temperature than those regularly experienced, while in the meantime producing a better quality product that fulfills Requirements of various standards. Several works, carried out in different laboratories demonstrate that the addition of a small quantities of these mineralizers have a major impact on the determination of the burning zone clinkerization and the percentage of clinker compound formation. They majorly affect the determination of the burning zone and the clinker compound formation, they can facilitate and quick the clinkerization process, by decreasing the liquid phase temperature and mineral fusible eutectic in the aim of saving the clinker production energy and improving the cement compound reactivity [2, 3]. They can improve the hydraulic properties of clinker [3, 6-13]
