The differences in the resistance to corrosion GF cement and ordinary portland cement are due to different microstructural characteristic, above all significantly lower porosity of hardened GF cement pastes and concretes. The hardened GF cement pastes and concretes are corroded by the same mechanism (corrosion of the 2nd and 3nd types) as the corresponding PC materials. The difference between GF cement and PC is based on the corrosion rate, which is much lower with the GF cement materials.
