Methods of test for screed materials - Part 8: Determination of bond strength

This European Standard specifies a method for determining the bond strength between a screed and a standard substrate and specifies a method for determining the tensile strength at the surface of specimens made from cementitious screed-, calcium sulfate, screed-, magnesia screed- and synthetic resin screed material. The method is also suitable for floor screeds for determining the tensile strength at the surface of the floor screed or for determining the bond strength between a bonded floor screed and a base.

The bond strength is calculated as the quotient between the failure load and the test area. The test area isdefined by coring or cutting through the screed into the substrate.4 Symbols and abb
