Phosphogypsum used as pavement base material is one of the efficient ways to realize the resource utiliza-tion of industrial solid waste.However,due to the high natural moisture content of phosphogypsum and its high fluctu-ation,the traditional drying method is time-consuming and consumes electricity to measure the moisture content.Therefore,the microwave heating method was used to detect the natural moisture content of phosphogypsum.The in-fluence of different moisture content,sampling weight,heating time and sample amortization thickness on the heating loss of phosphogypsum free moisture and crystal water was analyzed,and the rapid determination method of natural moisture content of phosphogypsum based on microwave heating was proposed.
