| Sustainability concerns related to the CO2 emissions of Portland cement production led to the exploitation of some by products as replacement materials, such as slag. This requires a good understanding of the blended cementitious materials at the microscale to fully explain the observed behavior of the structures at the macroscale. The nanoindentation technique was used to assess the ef...

| Using supplementary cementitious materials (SCM) can help increase the sulphate resistance of cement blends. However, formulating sulphate resistant materials with increasing amounts of SCM is challenging, and the required standard tests last several months. Therefore, creating new tools that can be easily applied and understandable could help develop novel materials in the future. Machine learnin...

| The accelerated carbonation of recycled concrete aggregates (RCA) has been suggested to improve their properties. Several physical and mechanical phenomena occur during the carbonation of adhered cement mortar, but the relationship between bound CO2 content and the variation of RCA properties is not clear. In this study RCA and model materials (spheres) have been exposed to carbonation,...

| Chloride induced corrosion on reinforcing steel is one of the main causes that may shorten the service life of concrete structures. Recent studies have found that the deterioration process of these structures is highly influenced by material properties, environmental factors (exposure conditions) and climatic conditions (such as temperature, humidity, seasonal variations, etc.). For infrastructure...

| Alkali Activated Materials (AAM) are considered an alternative to cementitious binders. Due to the reduction of Portland cement content and using industrial wastes to produce it, AAMs gained the researcher's interest in the last decades. Current researches show that mechanical properties and ability to ensure proper conditions for reinforcing steel of AAMs are at least as good as for Ordinary Port...

| In this paper we investigate the role of seismic slip velocity in the thickness evolution of a faults principal slip zone (PSZ) during coseismic slip. The PSZ of a fault can be modelled as a shear band of evolving thickness (see [33]). The PSZ thickness is associated with energy dissipation and apparent frictional softening during earthquakes. We use numerical non linear analyses that take into ac...

Literature shows different process methods carried out by researchers and engineers to obtain the data needed to select suitable parameters. These methods can be divided into destructive, based on macrostructures analyses, and non destr...

| Early age cracking is a high risk for low water to cement (w/c) concrete known as the ultra high performance concrete (UHPC). The lack of water to fully hydrate cement particles at the early age, provides a rapid increase of self desiccation and autogenous shrinkage which might lead to cracking. However, internal curing agents such as superabsorbent polymers (SAP) can reduce/eliminate crack develo...

| Modelling natural composites, as the majority of real geomaterials, requires facing their intrinsic multiscale nature. This allows to consider multi physics coupling occurring at the microscale, then reflected onto the macroscopic behavior. Geotechnics is constantly requiring reliable constitutive models of natural composites to solve large scale engineering problems accurately and efficiently. Th...

| Blast furnace slag (BFS) is an industrial by product that has been used to replace clinker in Ordinary Portland Cement (OPC) to reduce the CO2 footprint impact in the construction field. Moreover, the use of BFS leads to an enhancement in terms of mechanical and durability properties. A solid comprehension of hydration properties is essential to achieve a better understanding of durabil...

| Shear failure is one of the most catastrophic mode of failure in reinforced concrete elements. In order to prevent shear failure, the factors responsible for shear capacity and shear transfer mechanisms should be completely understood. These mechanisms involve aggregate interlocking, the compression zone, the dowel action and the residual tensile stresses of the concrete. Further, these mechanisms...

| Predicting temperature field in a Gas Tungsten Arc Welding process is essential and precondition for any study of thermal or mechanical behavior of the weld. In fact, thermal, material proprieties and physical phenomena have to be taken into account in order to predict welding morphology, residual stresses and the final product quality of the weld. In the case of analytical studies, simulations ar...
