Abstract

In this study the cracking and debonding behaviour of cementitious screeds bonded to concrete bearing floors is analysed. In order to obtain insight in this behaviour research is performed to the surface tensile strength of concrete, the bond strength of screeds on concrete bearing floors, the behaviour of screeds during shrinkage and the methods to determine the bond strength. This research is carried out by a theoretical study in which the screed shrinkage behaviour as well as the screed / concrete behaviour during testing of the bond strength is analysed by means of analytical and FEM studies. Besides this practical experiments are performed to obtain insight in the influence of different parameters on the surface tensile strength of concrete / the bond strength of screeds on concrete bearing floors. Furthermore practical experiments are executed to study the influence of different parameters on the outcome of a preferred bond strength testing method.
