    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.

    Effect of silica fume in concrete | Silica fume supplier

    The incorporation of silica fume in concrete can improve the “stability” of concrete, which can reduce the segregation and bleeding of concrete. The sand and stone in the concrete will cause the internal gap to become larger due to the larger size, and the small diameter of the silica fume particles can fill these gaps and cut off the flow passage of the bleeding process.

    Silica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm. This makes it approximately 100 times smaller than the average cement particle. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 600 kg/m 3.The specific gravity of silica fume is generally in the
