Abstract

A cementitious composition (1) which, in the hardened state, acts as a low leaching coating in low alkalinity and low hardness waters. The composition comprises at least one cement and a highly reactive pozzolan. The cementitious composition can be applied to a surface such as a metallic drinking water pipe (2) in order to provide corrosion protection therefor.
