Permeability is dramatically reduced, which makes microsilica ideal for applications where concrete will be required to resist chemical attack. Resistance to corrosion is increased because concrete is more resistant to water ingress and therefore also to corrosion caused by sulfates and water-borne chlorides such as deicing salts.
Advantages of silica fume in concrete: (1) silica fume is a kind of neutral inorganic filler with very stable physical and chemical properties. It does not contain crystalline water, does not participate in the curing reaction, and does not affect the reaction mechanism.
