Cementitious Coatings

Cementitious coatings provide corrosion resistance to substrates such as

steel by maintaining the pH at the metal/coating interface above 4, a pH

range where steel corrodes at a low rate. The proper selection of materials

and their application is necessary if the coating is to be effective. To select the

proper material, it is necessary to define the problem:

1. Identify all chemicals that will be present and their concentrations.
