EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 772-14 testing. This European standard specifies a method for measuring the moisture movement of aggregate concrete and fabricated masonry units between two specified extreme moisture conditions.
EN 772-14 is a European standard that specifies a test method for determining moisture movement of aggregate concrete and manufactured stone masonry units. Moisture movement is an important characteristic of masonry units as it affects their resistance to water penetration, durability and overall performance.
The test method specified by EN 772-14 involves measuring the dimensional changes of a test sample of the wall unit in response to changes in moisture content. The test sample is typically a rectangular block, dimensions specified by the standard.
The test sample is first conditioned to a certain moisture content and its initial dimensions are measured. The sample is then subjected to a cyclical change in relative humidity and the moisture content varies between specified limits. The cyclic variation in relative humidity is achieved by placing the sample in a controlled environment chamber where temperature and humidity are controlled.
During the cyclical change in relative humidity, the dimensions of the sample are measured at specified intervals. The variation in length and width of the sample is recorded, and moisture movement is calculated as the maximum difference in size expressed as a percentage of the original size.
The standard specifies the procedures and equipment required to perform the test, including the use of a controlled environment chamber, measuring instrument and sample with a certain accuracy, and procedures for controlling temperature and humidity.
In general, EN 772-14 provides a standard method for determining moisture movement of aggregate concrete and manufactured stone masonry units. This information is essential for ensuring the quality and performance of wall units in a variety of applications, including building construction, landscaping and infrastructure projects.
