The effect of curing temperature on white cement hydration

摘要: Abstract Cement manufacture has undergone extensive change in its attempts to rise the successive challenges posed by society. The hydration of Portland cement is a complex phenomenon that depends on both reagent characteristics and reaction conditions. It well-known fact curing temperature plays an important role kinetics. present study first be undertaken effect white paste over long times (365 days at 20 °C 124 60 °C). technique used, 29Si 27Al NMR spectroscopy, particularly well adapted hydration. White generates C–S–H gel which aluminium taken up forms bridge bonds. After nine 60 °C, degree expressed terms Al(IV)/Al(VI) ratio nearly doubles value found after 90 20 °C.
