Johnson Alengaram, M. N. Oudjit, Australian Journal of Civil Engineering, Vol. 22, issue 1, pp. 94-107 (2024), doi:10.1080/14488353.2022.2131949
| Cement is one of the main sources of negative environmental impact of concrete. One way to reduce this impact of concrete could be through the reduction of the cement content. This could be achieved by replacing a part of cement with mineral additives such as fly ash, blast furnace slag, silica fume, metakaolin (MK), etc. in concrete. In this paper, the effect of curing temperature on MK blended c...

| Among earthen construction techniques, cob might be an interesting solution to mitigate greenhouse gases emissions and energy consumption of the building industry. One main issue encountered is that the cob material shows large variability of hygrothermal properties, which could consequently have an impact on the reliability of the estimation of the energy consumption of cob buildings. At the wall...

| Permeability is a fundamental property of porous media. It quantifies the ease with which a fluid can flow under the effect of a pressure gradient in a network of connected pores. Porous materials can be natural, such as soil and rocks, or synthetic, such as a densified network of fibres or open cell foams. The measurement of permeability is difficult and time consuming in heterogeneous and anisot...

| The Morison's equation continues to be an important approximation of the load effect of waves on structures. However, such forces can evolve with time due to marine growth and the evolution of long term growth within the Morison equation is challenging. Incorporation of long term marine growth gives rise to two timescales associated with the Morison equation. A short time scale is associated with ...

| [47] | | A Hydraulic Gradient and Stress-Controlled Erosion Apparatus for Assessing Soil Internal Erosion, Didier Marot, Bikram Oli, Fateh Bendahmane, Rachel Gelet, Philippe Leroy, Geotechnical Testing Journal, Vol. 47, issue 6, pp. 1205-1228 (2024), doi:10.1520/GTJ20230454
| Among the four dominant mechanisms of internal erosion, suffusion appears as one of the most complex. It is indeed the result of the combination of three processes: dislodgement of fine particles, transport of them, and filtration of some fluidized fine particles. These processes depend on the soils stress state and on the hydraulic gradient path. Thus, to ensure the repeatability of the suffusion...

| Multiphysics processes are common in nature and can occur in conjuction with intense strains. When strain softening is also present, the original uniform strain distribution is lost and strain localization occurs. In a classical continuum strain localization happens on a mathematical plane (i.e shear band of zero thickness). This leads to mesh dependent numerical analyses, in which strain localize...

| Slag cements are used to design grouts with high water to cement ratio and low permeability, to improve the physical and mechanical properties of permeable soils. Because of the variable physico chemical properties of slag, it can be challenging to predict their behavior. Most research on slag reactivity involves low water to binder ratios in concrete and strength. This study investigates grouts w...

| The common phenomenon observed for concrete in aggressive water is leaching, which involves the dissolution of cement hydration products. Many studies have focused on leaching in demineralised water or acid attacks, but mineral water still deserves further investigation. In most standards, the aggressiveness of a given water body is determined by its pH and not its composition. The effect of the c...

| Deep Geothermal Energy, Carbon Capture, and Storage and Hydrogen Storage have significant potential to meet the large scale needs of the energy sector and reduce the CO2 emissions.

| Sustained mechanical and environmental loadings on offshore structures result in creep phenomena. Creep and relaxation significantly affects the development of strains and stresses, thus they influence the durability of structures. Creep originates from the behaviour of the phases within the cement matrix. Seawater modifies the phases composition of cement matrix because of the variety of ions and...

| With the development of marine renewable energies, the durability of materials at sea is more than ever a major issue in reducing the risk of failure of offshore devices. In this aggressive environment, elastomers, and in particular polychloroprene (CR), have many applications because of their good damping and fatigue properties. However, these materials are subject to ageing in service, which lea...

| A classification of whispering gallery modes has been proposed between three types : core modes, cladding modes and composed modes. While core modes or cladding modes are interesting to generate with a sensor purpose, composed modes propagate in both core and coating and therefore should be avoided.

| [85] | | Development of accelerated test methods by electromigration to assess the risk of internal sulfate attack in heat-cured mortar and concrete, Van Huong Nguyen, Nordine Leklou, Pierre Mounanga, Construction and Building Materials, Vol. 455, number 139185 (2024), doi:10.1016/j.conbuildmat.2024.139185
| Internal sulfate attack induces the formation of delayed ettringite (DEF) in hardened cement based materials. DEF is a complex phenomenon, detrimental to the durability of concrete and which develops in the long term, depending on the temperature history of the material at early age, its composition, its physicochemical and mechanical properties, and the environmental conditions. Today, the risk a...

| [86] | | Path differences between quasistatic and fatigue cracks in anisotropic media, Xinyuan Zhai, Thomas Corre, Ataollah Mesgarnejad, Alain Karma, Veronique Lazarus, Physical Review E, Vol. 110, issue 6 (2024), doi:10.1103/PhysRevE.110.L063001
| We report experimental observations demonstrating that, in anisotropic media, fatigue cracks under cyclic loading follow strikingly different paths than quasistatic cracks under monotonic loading. We find a qualitatively similar behavior in a computational model, which suggests that this path difference is a general phenomenon. In both experiments and computations, quasistatic cracks follow paths ...

| Cryodeformed (CR) materials have complex microstructures containing nano twins, dislocation clusters, tangles, and others, depending on the stacking fault energy (SFE). Such unique microstructure makes them suitable for several engineering applications under a high strain rate environment. The high speed deformation (HSD) behavior of CR materials is difficult to understand due to their complex mic...
