TL;DR: In this paper, a mesostructural model for the mechanical behavior of heterogeneous quasi-brittle materials is used systematically to analyze concrete specimens in 2D. The numerical model is based on the use of zero-thickness interface elements equipped with a normal-shear traction-separation constitutive law representing non-linear fracture, which may be considered a mixedmode generalization of Hillerborg's “Fictitious Crack Model.

TL;DR: In this article, a comparative study of the LCIA of different life cycle inventories (LCI) for EU cements is presented, where the main environmental interventions related to cement manufacture were classified and characterised and their effect on different impact categories analysed.

TL;DR: In this article, a comparative analysis of inventories of several different types of cement produced in Europe is presented, considering the production of 1 kg of cement from cradle to gate, and all results are based on this mass unit.

TL;DR: In this article, the authors present three real experiences that are representative of the application of FRC in urban tunnels and a design methodology to take into account the structural contribution of the fibres.

TL;DR: In this paper, the pullout response of inclined fibers with hooked ends has been investigated and several experimental results were considered to validate the approach and to assure its suitability on distinct material properties and boundary conditions.
