【Abstract】 For the application of wet phosphoric acid by-product phosphogypsum in the building materials and its development both at home and abroad, the pilot testing flow of using phosphogypsum to make high-strength building blocks is introduced, and it is pointed out that by mixing additional material in the phosphogypsum and using special compound process, new functional building materials like gypsum-based conducting material and gypsum-based magnetic material can be produced. It not only expands the application of phosphogypsum, but also brings huge economic benefit.更多还原
