文摘

Silica fume increased the compressive strength of alkali activated slag concrete. Application of silica fume reduced the initial and total water absorption of AAS concrete. Application of SF increased the resistance to penetration of chloride ion in AAS concrete. Water curing lead to higher compressive strength, lower permeability and higher durability. Application of SF significantly reduced the porosity and permeability according to SEM images.
