Experiential investigation on the effect of heavy fuel oil substitution by high sulfur petcoke on the physico-mechanical features and microstructure of white cement composites

Abstract The current research paper study the effects of producing white cement using high sulfur petroleum coke (WC PC ) instead HFO ). White Cement production needs huge amounts thermal units from and it most consumed energy all over world. There are many interest to burn alternative sources aiming decrease in combustion cost secure surround environment. Current technologies allow burning fuel With a percentage such as PC, have least environmental damage generate amount fly ash. contains one third or less (S) than PC. High concentration cement/clinker granules cause series adverse on its applications due formation big anhydrite (CaSO 4 -insoluble) & aphthitalite (3K 2 SO ·Na reduce thenardite (Na leaves cracks, endearments yellowish color for skin coat, painting decoration applications. content comes accordingly increases setting time, compressive strength, workability sodium equivalent O Eq content, while whiteness reflection (Ry) degree.
