| Delayed Ettringite Formation (DEF) is an internal sulfate attack caused by heat induced decomposition and/or prevention of normal ettringite formed during the initial hydration of cement at elevated temperature (above about 70°C) and its re crystallization in the hardened matrix. This reaction is a physico chemical phenomenon inducing an expansion of the cement paste that could lead to cracking of...

| The combination of Portland cement and mineral additions allows reducing the carbon footprint of cement based materials and improving their resistance to several environmental actions. The development of binary binders is limited by the reactivity of pozzolanic materials at high substitution levels and the availability of industrial by products such as slags and fly ash. Thus, it is necessary to d...

| We present a model of material degradation relying upon a local damage law supplemented by convex constraints. This results in a damage model with bounded variation that is shown to share the same features of the so called Thick Level Set approach. Unlike the original model, in the present formulation the level set based representation is abandoned in favor of an implicit description of damaged re...

| With the new developments of floating offshore wind turbines (FOWT), wind farms are located in deeper water, meaning they are closer to traffic cargo and passenger lanes, increasing probability of collision. This paper aims to analyze the crashworthiness of a spar FOWT by performing non linear finite element simulations, which in the future will serve to validate a simplified analytical method for...

| [5] | | Investigation of the effect of irradiations on the mechanical and physico-chemical properties of cementitious materials: from the nanoscale to mortarsscale, Maxime Robira, Benoit Hilloulin, Ahmed Loukili, Gildas Potin, Xavier Bourbon, Abdessalam Abdelouas, CIGOS 2019, Innovation for Sustainable Infrastructure, Vol. 54, pp. 639-644, ISBN:978-981-15-0801-1, Springer Singapore (2020), doi:10.1007/978-981-15-0802-8_101
| Concrete is commonly used in nuclear construction for decades. Because low dose irradiations may play an important role regarding the extension of service life of some structures and long term properties of waste storage galleries, in depth studies are necessary. A multiscale experimental campaign on irradiated cementitious materials from mortars to pure phases (C S H) has been carried out and t...

| The efficiency of an optical sensor embedded in a composite structure strongly depends on the interfacial adhesion between the optical fiber coating and the surrounding solid material and on the environment humidity. Moisture diffusion can induce a decrease of the mechanical stiffness and strength of organic matrix composites. The present work reports on the study of the interfacial adhesion of an...

Colina, External Sulphate Attack Field Aspects and Lab Tests, Vol. 21, pp. 71-80, ISBN:978-3-030-20330-6, Springer International Publishing (2020), doi:10.1007/978-3-030-20331-3_6
| During external sulphate attack, the penetration of sulphates within the material is the rate limiting step. Thus laboratory tests can last a few years before giving usable results. It is possible to shorten the response time by stimulating the penetration of sulphates. One way to achieve that is to dry the material at 60 °C then to saturate it with a sulphate solution before the test. The impact ...

| Through the study of binary and ternary blends, the work is focused on the influence of the substitution of the cement by calcined clay and/or limestone filler on the mechanical properties. Besides of an ordinary Portland cement, three binders were analyzed: one binary blend where 30% of the cement is replaced by calcined clay and two ternary blendsone with 15% of calcined clay and 15% of limeston...

| This paper presents a simplified method to assess the whipping response of a surface ship subjected to underwater explosion, without modelling explicitly the surrounding water. The early time action of the shock wave generated by the detonation is treated using Taylors theory. Then, a bubble of gas starts to pulse and the incident pressure coming from resulting water flows, which usually couples w...

| In the recent years, automotive car industry is evolving towards a new generation of autonomous vehicles, where decision making is not fully perform by the driver but it partially relies on the technology of the car itself. Indeed, a CPU inside the car will process all information coming from the sensors, distinguishing different scenarios appearing in the real life and ultimately allowing decisio...

| The rheology is the key factor that controls the 3D printability of cement based materials. Indeed, the printed material should satisfy both good workability retention to ensure successful extrusion and a well adapted green strength to support subsequent layers without collapsing. This requires a tricky control of the physico chemical structuration kinetics. In the present study, in addition to dy...

| This paper presents a review of the french teaching of numerical methods in the field of civil engineering and their applications on geotechnics (Engineers School and University). A survey on 114 courses has shown two types of course: basic courses and specialized courses (rheology, statics, dynamics, seismic, seepage, hydro thermo mechanics). Programs and teaching methods are discussed and compar...
