Silica Fume Concrete (Microsilica) CivilWeb Spreadsheets

Silica fume concrete is more expensive than GGBS or Fly Ash concrete and increases the overall costs of the concrete where other supplementary cementitious materials reduce the costs. However microsilica in concrete has several beneficial effects on the concrete produced including higher strength, lower permeability and greater abrasive resistance.

Nov 30, 2020 Silica fume, a by-product of the ferrosilicon industry, is a highly pozzolanic material that is used to enhance mechanical and durability properties of concrete. It may be added directly to concrete as an individual ingredient or in a blend of portland cement and silica fume. In the United States, silica fume is used predominantly to produce concrete with greater resistance to chloride

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.
