Title: 2nd International RILEM/COST Conference on Early Age Cracking and Serviceability in Cement-based Materials and Structures (EAC-02) Volume 2 Edited by: Stéphanie Staquet and Dimitrios Aggelis e-ISBN: 978-2-35158-198-8 ISBN: 978-2-35158-200-8 Pages: 439 Publication date: 2017

We are honored to organize and host the 2nd International RILEM/COST Conference on Early Age Cracking and Serviceability in Cement-based Materials and Structures EAC-02, 12-14 September 2017 in Brussels in Belgium in conjunction of the annual scientific meeting of the COST Action TU1404 (http://www.tu1404.eu). The conference is scientifically endorsed by RILEM.
This COST Action TU1404 is entitled: “Towards the next generation of standards for service life of cement-based materials and structures”, dedicated to assist deepening knowledge regarding the service life behavior of cement-based materials and structures. The main purpose of this Action is to bring together relevant stakeholders (experimental and numerical researchers, standardization offices, manufacturers, designers, contractors, owners and authorities) in order to reflect today’s state of knowledge in new guidelines/recommendations, introduce new products and technologies to the market, and promote international and inter-specialty exchange of new information, creating avenues for new developments.
The COST Action TU1404 is basically divided in three main workgroups targeted to: WG 1 – Testing of cement-based materials and RRT+WG 2 – Modelling and benchmarkingWG 3 – Recommendations and productsAlso, two important instruments of the Action are under way: the Extended RoundRobin Testing Program (RRT+) and the numerical benchmarking. The RRT+ is currently involving 42 enrolled laboratories.
This International RILEM/COST Conference follows the RILEM InternationalConference on Early Age Cracking in Cementitious Systems (EAC’01) organized inMarch, 2001, in Haifa, Israel, by Prof. Konstantin Kovler. The EAC’01 conference was dedicated to early age cracking in cementitious systems, one of the most prominent topics tackled by COST Action TU1404. Indeed, this Action includes in the working group 1 (WG1) the following priorities: fresh properties and setting, chemical and microstructural characterization, transport properties and boundary effects, mechanical properties and creep, volume stability and fracture properties and cracking. In the working group 2 (WG2), this Action includes the following priorities: microstructural modelling, multiscale modelling, macroscopic modelling, probabilistic modelling and benchmarking calculations. It is the reason why, to continue the tradition of the specific conference EAC’01, the idea came naturally to organize the EAC-02 conference in conjunction with the annual event of the COST Action TU1404.
The present conference deals with a wide breadth of topics related to early age cracking of cement-based materials and to the service life of concrete from nano up to macro scales including both material and structural scales and comprising aspects related to the 3 Workgroups mentioned above. The conference is attended by 165 participants including 12 invited plenary speakers and 140 presenters from university, industry and practice representing more than 30 different countries. All contributions have been peer reviewed. The event takes place in Brussels, at the campus of the Université Libre de Bruxelles, 12-14 September 2017. It is a great pleasure to welcome you in Brussels,the capital of the European Union, having a long history of hosting the institutions of the European Union, a place with a rich history and vibrant activities situated in the heart of Europe.Welcome to Brussels, an open and cosmopolitan city where 183 nationalities live side by side!
