Currently, in industrialized countries in order to prevent corrosion of the hydration-hardened building products a tendency to use methods reducing the permeability of concrete to aggressive agents of the environment is applied. The authors believe that to protect concrete and reinforced concrete against corrosion, it is necessary to use all available means at the disposal of specialists, the most important of which is the correct choice of cement. Increasing corrosion resistance by reducing the water-cement ratio of the concrete mixture is a universal way, but not always it can ensure preserving the performance properties of concrete products and structures in aggressive environments for their entire service life. In this regard, recommendations for choosing the type of cement for the most frequently encountered aggressive environments are given. The analysis of literature sources shows that in many cases it is advisable to use cement with active mineral admixtures.
