Further works on concrete at early age coordinated within COST TU1404 European project

The working group 1 (WG1) of COST Action TU1404 European project is entitled “Testing of cement based materials and RRT+”. It deals with determination of different properties of early age and hardened cement based materials with the following main objectives: (1) to recommend new advanced standard techniques which have been developed during the last years to become standard in the (near) future and (2) to prepare a database of cement-based materials at different scales (paste, mortar and concrete) which could serve designers and engineers to better predict lifespan, durability, and serviceability of concrete structures. This paper describes the organization and the strategic view of WG1, presents its main objectives and gives the details about the calibration phase for the mix design optimization and the content of the main phase of the extended Round Robin Test (RRT+) that has been launched recently with 42 laboratories.
