EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 772-5 testing. This European standard specifies a method for determining the active soluble salt content of clay masonry units.
The adopted method is based on water extraction from a broken representative sample of clay wall units and determines the amounts of soluble magnesium, sodium and potassium ions released under the test conditions and which can be attributed to the potentially damaging effect of clay salts. These ions are found on cementitious mortars and even on units in certain cases.
The sampling method will be in accordance with EN 771-1. The minimum number of samples to determine the active soluble salt content will be six and include all units, although a larger number may be specified in the product specification, in which case the larger number will be used. Samples will be collected in a manner that will not expose the units to water that would cause leaching of soluble salts.
This test is used to determine the amount of soluble salts inside clay masonry units and to evaluate the usability of these units in construction projects. Active soluble salts can cause various problems if they exceed salt threshold values in building materials, so it is important to determine the content of these salts.
EN 772-5 provides a standard approach to the process of determining the soluble salt content of clay masonry units. This increases comparability between materials. The use of this standard provides a standard in the process of determining the amount of soluble salts within clay masonry units, which helps evaluate the safe use of these units in construction projects.
