The study of manufacture technologies and provenance of raw materials in archaeological potteries are two fundamental aspects in providing information about sociocultural aspects on past societies. The most acknowledged technique in this field is represented by minero‐petrographic analysis, allowing to describe the compositional features of the art...

A temperature rise in soils is usually accompanied by an increase in excess pore fluid pressure due to the differential thermal expansion coefficients of the pore fluid and the soil particles. To model the transient behaviour of this thermally induced excess pore fluid pressure in geotechnical problems, a coupled THM formulation was employed in thi...
L’étude des sols argileux fait l’objet de nombreux travaux motivés par leur rôle dans les processus d’érosion, les catastrophes naturelles et l’agriculture de précision. La quantification des argiles gonflantes est aussi nécessaire pour évaluer la traficabilité d’une région ou le risque de retrait-gonflement des sols, responsable d’engendrer des dé...
This work aims to study an aluminosilicate phosphate cementitious matrix. The cementitious matrix was studied on paste samples. The synthesis of metakaolinite phosphate cement (MKPC) was investigated using calorimetric techniques. A systematic study was performed by emphasizing a broad range of Al/P molar ratios, covering the different behavior of ...
At sufficiently low applied shear deformation or shear stress, fresh cement paste exhibits viscoelastic solid-like behavior. This solid-like state is particularly important for some applications, such as self-consolidating concrete formwork pressure and 3D concrete printing. In this study, the viscoelastic solid-like behavior of fresh cement pastes...
The heat-transfer phenomenon in dry sands, which is generally looked at from the perspective of conduction, was studied with the thermal flux method (TFM) proposed in the literature. However, when results from the TFM were compared with those obtained from the numerical simulation, a substantial disparity was noticed. Through careful analysis of th...
Unstabilized Rammed Earth (RE) has been historically used to form earth walls or blocks. Recently RE has resurfaced as a sustainable building material with little attention given to it in building codes and manuals. The percentage of the fine-grained fraction in RE is one of the most important factors affecting its behavior. Such percentage has bee...
Ground response to the construction of the Crossrail tunnels in London Clay beneath Hyde Park has been modelled numerically using advanced finite-element analyses. The soil model used for modelling the London Clay was a kinematic hardening soil model (named M2-SKH). This model, when used for the St James's Park greenfield site, provided excellent p...
