Utilization of the black tea powder as multifunctional

Furthermore, black tea alters the gypsum hydration process. It decreases the hydration rate and delays the hydration time of gypsum. Although more black tea seriously delays the gypsum hydration, all hemihydrate gypsum thoroughly converts into dihydrate gypsum after 28d. SEM results show that black tea changes the gypsum crystal morphology.
