Effect of Sodium Monofluorophosphate Treatment on Blast Furnace Slag Cement Paste Microstructure

Blast Furnace Slag (BFS) is a latently hydraulic material used as additive or substitute for Portland cement. The market share for BFS cement in the Netherlands is currently more than 60%. Previous research proved the high resistance of slag-rich concrete in aggressive environments such as exposure to acid, chloride ingress or sulphate attack,...

Application of encapsulated lightweight aggregate impregnated with sodium monofluorophosphate as a self-healing agent in blast furnace slag mortar

This paper studies the potential of using expanded clay lightweight aggregate impregnated with sodium monofluorophosphate (Na2FPO3) solution which is eventually encapsulated by a cement paste layer to produce a self-healing system in blast furnace slag cement mortars. It was found that the technique significantly improved the quality of the...
