EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 772-2 testing. This European Standard specifies a method for determining the percentage area of voids in aggregate concrete masonry units.
The main purpose of the test specified in EN 772-2 is to determine the amount of voids in concrete masonry units and to help evaluate their suitability for various construction applications.
The standard details the principles behind measuring the percentage of free space. This typically involves calculating the gross volume of the wall unit and subtracting the solid volume to determine clearances. After preparation of the samples, thick pieces of paper are pressed onto the test surfaces of the masonry units and the indentation is measured to give the percentage area of the voids.
The standard outlines step-by-step procedures for performing the test. This involves measuring dimensions, calculating volumes and determining the percentage of voids.
In general, this standard focuses on determining the void ratio, which can affect the structural and thermal properties of concrete wall units. The measurement is made by calculating the gross volume of the units and subtracting the solid fraction from this volume. In this way, important information is provided regarding the use of units in construction projects. EN 772-2 provides a standard method for assessing the quality of construction materials and determining correct practices.
