REAL FUME is a ready-to-use powdered micro silica concrete admixture that compiles with ASTM C1240 specification.

General Description REAL FUME reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that greatly enhances strength and durability. The ultra fine micro silica fills the voids between cement particles creating a highly dense, less permeable concrete.
Appearance - Gray powder
Specific gravity - 2.0
Bulk density approximately - 400 - 600 kg/m³
Recommended For
Bridge decks
Parking structures
High density concrete
High strength concrete
Marine environments
Precast concrete and etc
Basement and underground structures
Advantages /
High early strength gain for faster turnaround time
Greatly improved freeze/thaw and scaling resistance
Low permeability for greater resistance to water and salt penetration
Increases abrasion and chemical resistance for a longer life expectancy
High ultimate compressive and flexural strength for stronger and durable structural capacity
Improves concrete performance to reduce column size, increases production and lower transportation and erection costs
Recommended Dosage REAL FUME is normally used at the rate of 5% - 15% by weight of cement. It is batch at the ready-mix plant in a manner similar to cement or other cementitious materials such as fly ash and granulated slag.

REAL FUME is recommended to be used with a high-range water reducer in order to provide maximum workability while maintaining the desired low water/cement ratio.

Note: For direction on the proper use of REAL FUME in specific applications, please contact our sales representative.
REAL FUME is supplied in bulk by tanker, 20kg and 25kg bag and also available in 1.2 m/ton bulk bag.
Storage / Shelf Life REAL FUME can be stored for 6 months in tank and 1 year in tightly sealed original bag.
