EXTENDED ROUND ROBIN TESTING PROGRAMME

The extended round robin testing program (RRT+) is a fundamental mechanism used to achieve the objectives of WG1. The main objectives of RRT+ are twofold: (1) to provide better understanding of the behaviour of cement-based materials (CBM) themselves (database of properties), especially high-performance and eco-concrete, which will offer new opportunities to simulation/predictive models both in terms of validation of modelling assumption/strategies and opportunities for the validation of simulation results and (2) mutual validation of advanced, non-standardised experimental techniques developed in laboratories. This will highlight the validity and added value of newly developed techniques, and lead to standardization of more precise and property targeted methods for testing CBM.
