Analysis of physical characteristics and mechanism of retarder to stratified cemented backfill [PDF]
Scientific ReportsThe stratified structural plane caused by stratified backfill will reduce the strength of backfill, and the introduction of retarder will make up for the defect. Three retarders, sodium tripoly-phosphate, citric acid and sucrose, were introduced.
