Quality of realisation of the joints between floor plates

A concrete floor plate system is composed of a juxtaposition of floor plates. Between the floor plates lies a small play that is filled with a joint. It is realised after the placing of the floor plates.
Thanks to the development of a performance test method to evaluate the cracking resistance of joint products, the study enabled to identify the main parameters influencing the quality of the joints between floor plates.
Recommandations on the realisation of the joints between floor plates have been defined. They deal particularly with the moment of placing the joints and their capacity of strain.
