1. INTRODUCTION
1.1. WORKSHOP
The 2nd workshop of the Action with focus on Modeling of Cement Based Materials and Structures will take place on 19-20 September 2015 together with the 2nd MC meeting of the Action (20 September 2015) in Vienna, Austria at the Vienna University of Technology (TU Vienna/TU WIen). The workshop will precede the CONCREEP Conference (21-23 September 2015). The details on the workshop can be found on the Action website: http://www.tu1404.eu/september-2015-vienna
1.2. ABOUT COST
Founded in 1971, COST – European Cooperation in Science and Technology – is the first and widest European framework for the transnational coordination of nationally funded research activities. It is based on an inter-governmental agreement between 35 European countries. COST enables break-through scientific developments leading to new concepts and products and thereby contributes to strengthen Europe’s research and innovation capacities. It is a unique means for European researchers to jointly develop their own ideas and new initiatives across all scientific disciplines through trans-European networking of nationally funded research activities. COST key features are:
Building capacity by connecting high-quality scientific communities throughout Europe and worldwide;
Providing networking opportunities for early career investigators Increasing the impact of research on policy makers, regulatory bodies and national decision makers
as well as the private sector.
Through its inclusiveness, COST supports integration of research communities, leverages national research investments and addresses issues of global relevance. As a precursor of advanced multidisciplinary research, COST plays a very important role in building a European Research Area (ERA). It anticipates and complements the activities of the EU Framework Programmes, constituting a “bridge” towards the scientific communities of emerging countries. It also increases the mobility of researchers across Europe and fosters the establishment of scientific excellence in the nine key domains:
Biomedicine and Molecular Biosciences Food and Agriculture Forests, their Products and Services Materials, Physics and Nanosciences Chemistry and Molecular Sciences and Technologies Earth System Science and Environmental Management Information and Communication Technologies Transport and Urban Development Individuals, Societies, Cultures and Health
In addition, Trans-Domain Proposals allow for broad, multidisciplinary proposals to strike across the nine scientific domains. COST is funded through the EU RTD Framework Programmes.

1.3. COST ACTION TU1404
1.3.1. ABSTRACT
Cement-based materials (CBM) are the foremost construction materials worldwide. Therefore, there are widely accepted standards for their structural applications. However, for service life designs, current approaches largely depend on CBM strength class and restrictions on CBM constituents.
Consequently, the service life behaviour of CBM structures is still analysed with insufficiently rigorous approaches that are based on outdated scientific knowledge, particularly regarding the cumulative behaviour since early ages.
These results in reduced client satisfaction at the completion stage, increased maintenance/repair costs from early ages, and reduced service life of structures, with consequential economic/sustainability impacts. Despite significant research advances that have been achieved in the last decade in testing and simulation of CBM and thereby predicting their service life performance, there have been no generalized European-funded Actions to assure their incorporation in standards available to designers/contractors. Therefore, the main purpose of COST Action TU1404 is to bring together relevant stakeholders (experimental and modeling researchers, standardization offices, manufacturers, designers, contractors, owners and authorities) in order to accelerate knowledge transfer in the form of 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.
1.3.2. ACTION TU1404 WORKING GROUPS
In order to adequately achieve the objectives of the Action, three Work Groups (WG) have been defined as follows:
WG1: Testing of CBMs,
WG2: Modelling of CBMs and the behaviour of structures,
WG3: Development of recommendations and products.
WG1: TESTING OF CBMS
Chair: Gregor Trtnik [SI] Co-chairs: Marijana Serdar [CRO] Sreejith Nanukuttan (GB)
E-mail: [email protected] E-mail: [email protected] E-mail: [email protected]
WG1 deals with determination of different properties of early age and hardened cement based materials with the following main objectives: (1) to recommend new advanced techniques which have been developed during the last years to become standard in the (near) future, (2) to test the ability of using different waste, recycled, and by-products as raw materials to design sustainable concrete mixture, (3) to prepare a database of concrete mixtures which could serve designers and engineers to better predict lifespan, durability, and serviceability of concrete mixtures and structures, and (4) to provide input data needed for modelling phase of the Action (WG2). In order to achieve these objectives several Group Priorities have been specified to perform the experimental program systematically and Round Robin Testing (RRT) has been organized among the laboratories included in the Action. To determine properties of fresh and hardened materials, various experimental techniques have been used within RRT with a special focus on using self-
6
developed, advanced (non-destructive) testing techniques developed during the last years.
WG2: MODELLING OF CBMS AND THE BEHAVIOUR OF STRUCTURES
Chair: Mateusz Wyrzykowski [CH] Co-chair: Farid Benboudjema [FR]
E-mail: [email protected] E-mail: [email protected]
WG 2 deals with modelling of cement based materials and structures, with particular focus on durability and service life-related aspects. Modelling complements the parallel experimental studies by allowing for virtual testing of a variety of material parameters and boundary conditions on one hand, and extending beyond the time and space scales available in real experiments, therefore enabling long-term predictions of material or structural behaviour. WG2 will benefit from the synergistic cooperation with the other two WGs of this COST Action. The objectives of the WG are trifold: (1) to support unified approaches for conducting numerical experiments for material properties of CBM and (2) unified approaches for macroscopic modelling of CBM behaviour during the life cycle. The final objective is (3) to integrate the conclusions from different modelling scales (from cement paste to structural level) to create a set of general instructions to be used in designing software for CBM and reinforced concrete structures.
WG3: DEVELOPMENT OF RECOMMENDATIONS AND PRODUCTS
Chair: François Toutlemonde [FRA] Co-chair: Terje Kanstad [NOR]
E-mail: [email protected] E-mail: [email protected]
An adequate determination of the service life of concrete structures, namely in its less developed fields related to analysis and control of imposed deformations and control of their induced effects in combination with (loading) actions, requires accepted determination of relevant physical quantities. Proposals for comprehensive and upgraded test standards and development of associated devices thus constitute a first objective of WG3 based on the results of WG1. Moreover, after WG2 results in terms of check and comparison of computational methods to address control of structural deformations and cracking (as well as overall service life behaviour) and assessing associated typical precisions in their prediction ability, WG3 will draw general lessons and propose a methodology compatible with the Eurocode standard format to address thermo-hydro-mechanical coupled effects in serviceability design, including transient construction phases. In sum, WG3 will focus on identified shortages of present reference documents and on mature developments of tests, products and methods, to contribute to standards and guidelines improvement in the field of concrete service-life design.

2. WORKSHOP 2: FOCUS ON MODELING OF CEMENT BASED MATERIALS AND STRUCTURES
2.1. OBJECTIVES OF THE WORKSHOP
The 2nd workshop has several objectives related to WG2.
to promote scientific discussion on the modelling activities, models development, etc. between the members of the Action as well as with the invited external participants;
to integrate the modelling community within the Action; to discuss further developments leading to recommendations/guidelines in collaboration with
WG3; to share ideas and extend the contents of the simple benchmarking campaign; to discuss and define a draft of benchmarking activities related to the experimental results of
WG1; to discuss and define benchmarking activities related to case studies.
In addition to the scientific activities, the 2nd MC meeting of the Action will take place during the workshop (20 September 2015).
