Study on the Effect of Curing Conditions on Hydrate Properties of Fluorgypsum by Semi-Dry Pressing

Abstract:

The influence of different curing conditions on hydration properties of fluorgypsum products formed by semi-dry pressing was studied. Laboratory experiments were conducted to investigate the compressive strength development, content of crystal water, and microcosmic crystal structure when four curing methods (nature curing, curing in standard curing chamber, soaked in water 3 min every other day or every day) and five curing temperatures (-20 °C, 0 °C, 10 °C, 20 °C, 35 °C) were used. The results indicated that the hydration properties of fluorgypsum products could be improved under proper curing methods and lower curing temperature.
