How Does Silica Fume Work in Concrete?

Silica fume’s benefits are already evident in the fresh concrete state before it begins to harden. Its small particle size which is 100 times finer than ordinary portland cement complements the finess modulus of concrete and provides a ball-bearing effect, which improves thixotropic behavior, in effect modifying concrete viscosity.

Depending on the dosage of micro silica fume, the fresh concrete may be more cohesive and sticky than conventional concrete. Due to this cohesiveness, slumps 25 to 50 mm (1 to 2 in.) higher than normal should be used for similar types of placement. For ease of placement, the highest practical slump (attained through the use of superplasticizers) should be specified.

Effect of Silica Fume to Water Permeability of Concrete

Pores in concrete are reduced significantly with the inclusion of silica fume and illaries reduced through reduced bleeding and production of denser paste. The permeability is lower the higher the cement content of the paste i.e. the lower the water/cement ratio. Values obtained for pastes in which 93% of cement has hydrated. It is the permeability of the paste that has the greatest
