Abstract

This study explores the potential application of waste gypsum, particularly phosphogypsum (PG) in the field of intelligent construction. Through calcination pretreatment and 3D printing technology,the physical and chemical properties of phosphogypsum and their impact on 3D printing performance were investigated. Initially,the chemical composition and microstructure of the raw phosphogypsum were analyzed using X-ray fluorescence spectrometer (XRF), X-ray diffractometer (XRD), and scanning electron microscope (SEM). Subsequently, the effect of different calcination temperatures on the dehydration reaction and phase composition of phosphogypsum was studied through calcination treatment. Then, using 3D printing technology, the influence of different water-to-cement ratios (w/c) on the printability and mechanical properties of phosphogypsum paste was explored.The results indicated that the dehydration reaction of phosphogypsum was most significant at a calcination temperature of 175℃, and the 3D printing effect of phosphogypsum paste was optimal at w/c = 0.67,with the printed components being continuous, uniform,and smooth without defects. Additionally, calcined phosphogypsum exhibited the highest mechanical performance at w/c = 0.70. This study provides new ideas for the resource utilization of waste gypsum and is of great significance for promoting the development of intelligent construction technology.
