Abstract The research used industrial by-products original phosphogypsum (PG)
as the main raw material, slag (SG) and Portland cement (PC) as auxiliary materials, and the optimal additive amount was determined according to the compressive strength value of the sample. Comprehensively evaluate the water resistance
and volume stability of the samples, and determine the best formula for new
roadbed stabilized materials. The results showed that when the weight ratio of
PG, slag and cement was OPG:SG:PC = 6:3:1, and mixed with 5% micro silica
fume (MSF) and 3‰ hydroxypropyl methyl cellulose (HPMC), the sample’s
comprehensive performance was the best, specifically, the sample’s… More >
