Through the orthogonal experiment, the effects of different materials proportions on grouting material per-formance of walls prepared by phosphorus building gypsum are studied, and the best proportion is obtained with fly ash 10%, lime 3%, sodium citrate 0.1%, water reducer 0.6% and the ratio of water to phosphorus building gypsum 0.46. The performance parameters of the best proportion are as follows: 2h flexural strength 2.52MPa, 2h compressive strength 7.75MPa, initial setting time 14 min, final setting time 21 min, and fluidity 208mm, which can conform to the technical requirements of construction process of gypsum pouring on site as well as the strength of the non-bearing walls. Finally, the radioactivity of grouting material is analyzed further.
