Description

Technical Field

[0002] Phosphogypsum is an industrial byproduct emitted during the wet process of phosphoric acid production, and its main component is calcium sulfate dihydrate (CaSO4·2H2O). Studies have shown that phosphogypsum can be used as a raw material for highway construction, which can solve the problems of land resource occupation and environmental pollution, and promote the sustainable development of highway infrastructure construction. Therefore, phosphogypsum has become an important research hotspot in this field.

[0003] Phosphogypsum contains both adsorbed water and water of crystallization, with the adsorbed water content typically between 20% and 30%. Currently, the moisture content of phosphogypsum usually refers to the adsorbed water content. In practical applications, studying the dehydration process of phosphogypsum is of significant guiding importance for engineering construction. Most articles use the ratio of the amount of water dehydrated from phosphogypsum at a certain temperature to the dry basis weight obtained after dehydration as the moisture content of phosphogypsum. Since phosphogypsum generally loses its water of crystallization rapidly above 60 °C, the most commonly used method for determining moisture content is the drying method. This involves placing the phosphogypsum in an oven at 55–60 °C and drying it to constant weight before measuring its moisture content. However, this method usually requires a long time.
