Silica fume can be used either as a densified or undensified powder, a slurry, as combination at the concrete mixer, or part of a factory-blended cement. Generally, the comparisons are made against a concrete made with 100% CEM I (Portland cement). The following terms are used with specific meanings: – blending: mixing together cementitious components

The surface area of the cement particles of unit mass is called the specific surface area of the cement. It is represented by square centimeters per gram (cm2/g) or square meter per kilogram (m2/kg). The specific surface area of the cement is related to the fineness of the cement. The thinner the cement grind, the
