The conference “Materials, Systems and Structures in Civil Engineering – MSSCE 2016” is part of the RILEM week 2016, which consists of a series of parallel and consecutive conference and doctoral course segments on different topics as well as technical and administrative meetings in several scientific organizations. The event is hosted by the Department of Civil Engineering at the Technical University of Denmark and the Danish Technological Institute and it is held at the Lyngby campus of the Technical University of Denmark 15-29 August 2016. Some of the papers in these proceedings origin from the work in two COST actions: TU 1404 Service Life of Cement-based Materials and Structures and TU 1301 NORM for Building Materials. The papers from COST TU 1404 are spread across several MSSCE 2016 conference segments and it is planned that a separate set of electronic proceedings for this COST action will be published after the conference. This volume contains the proceedings of the MSSCE 2016 conference segment on “Fresh concrete”. The conference segment is organized by the Danish Technological Institute and Iffstarr. Knowledge and understanding of the fresh concrete properties, the casting process and the development in early age properties of concrete can contribute to improved design, execution planning and quality control ultimately resulting in higher quality of the final concrete structure. The segment deals with theory, modelling and results from experimental testing with relation to fresh and early age concrete. The topics covered include numerical simulations of mixing, casting and extrusion, mix design methods, quantification and assessment of constitutive material properties, mixing methods, rheology and thixotropy, early age modelling of concrete properties, non-destructive monitoring of fresh concrete, and assessment of value streams in precast castings. The conference segment is attended by persons from university, industry and practice representing different countries. The conference segment will serve as a platform for dissemination of state-of-the-art knowledge. Hopefully, it will contribute to synthesis of research on fresh concrete related topics
