Abstract: When water conduits ar made of concrete or are lined with cement mortar,the cement paste can be leached by water.
This occurs to a significant degree if the water remains in prolonged contact with the cement paste.
The consequences of leaching are an increase in pH and in the content of CaCO(3) .
Recent rules of the European Union endeavour to deal with this problem.
As the tolerable amount of leachate depends on the original properties of the water,tests are not easy to perform.
The use of admixtures and of high-alumina cement are discussed.
The actual levels of various chemical species indifferent waters in service and of tolerable quantities of these species need to be established so that a safe use of cement in conduits can be assured.
