Scope

This document specifies a standardised measurement procedure that allows mineral-bound building materials to be tested for their free water content. In addition to the usual measurement procedure for determining the free water content, the method can also be used for further characterisation of mineral samples with regard to their mixing ratio and the proportion of ettringite-bound water.

Purpose

The material moisture measurement of building materials with the carbide method is used worldwide. It is described in different national standards, like DIN 18560, SIA 253, UNI 10329 and also in Austria and France. The high precision of this chemical measurement method as well as the fast determination of measurement results make it a reliable measurement method for determining the water content of practically any porous as well as granular material sample.
