Corrosionpedia explains Mortar Coated Steel

Mortar coated steel has been used for many years as an efficiently protected material of choice for piping applications used to transport fluids. Its protective coat is equivalent to using a corrosion inhibitor on steel surfaces. It is however susceptible to damage due to sulfate and chloride infiltration.
