  • 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. Because of the high surface area of silica fume particles
