Cement mortar linings in drinking water pipes made of steel and ductile iron

摘要

For more than 100 years cement mortar has been used as internal corrosion protection for water pipes of steel and ductile iron. The combination of these 2 components has proved to be a perfect solution not only regarding the physical and mechanical aspects, also with respect to the corrosion chemical side for pipelines and construction pipes. This report gives a survey on questions that are often discussed in practical use concerning the possibilities and limits for the use of cement mortar linings in the drinking water area.
