In 2013, emissions of gypsum were about 1.84 × 10 12 t in China, but the comprehensive utilization rate was only 48.1% in that year. The accumulation of gypsum has potential hidden danger to groundwater and the surrounding environment. Therefore, expanding utilization of gypsum is the only way to enhance its comprehensive utilization rate [5].
