摘要
Abstract
Taking phosphate tailings in Guizhou as the aggregate, fly ash and cement were used as cementitious material to prepare cemented filling slurry.The effect of different amounts of citric acid on SO42-, F-in filling slurry bleeding and the bleeding rate was studied.The extended de-gree method, the fluidity method and the L tube method were employed to study the effect of differ-ent amount of citric acid on the flow performance of phosphate tailings slurry.The results showed that adding citric acid resulted in the increase of SO42-and decrease of F-in slurry bleeding, but had little effect on the bleeding rate.In addition, citric acid exhibited a retarding effect on the fill-ing slurry, which could improve the fluidity of the slurry.关键词
