Abstract: According to the physical, chemical and thermodynamic characteristics of yellow phosphorus slag as well as its activity principle, based on a large number of indoor tests and the compressive strength of fill in different period, the influences of types of alkali activator, dosage of alkali on compressive strength of cementitious materials filled with yellow phosphorus slag and its hydration reaction mechanism are analyzed. The results show that the yellow phosphorus slag is improved under NaOH and CaO activators, and the best dosage of that two alkalis are 5% and 8% respectively. The hydration product of yellow phosphorus slag includes C-S-H, in addition, the sulfate of the phosphogypsum also played a certain role in stimulating.
