Determination of Mohr–Coulomb failure envelope, mechanical properties and UPV of commercial cement-lime mortar
Matériaux et constructions - Tập 55 - Trang 1-19 - 2022
Mortar in masonry structures can be subjected to both uniaxial and triaxial loading. Determining the mechanical properties and/or failure criteria of the commonly used mortar is necessary for the structural performance assessment of new and existing masonry buildings using non-destructive testing and/or finite element modelling methods. In this paper, the stress–strain behaviour of a commercially ......
The influence of the chemical composition of hydrogels on their behavior in cementitious materials
Matériaux et constructions - Tập 54 - Trang 1-19 - 2021
This study examines how the chemical composition of hydrogels influences the behavior of hydrogels in cementitious materials. A stark contrast in the behavior of some hydrogels in extracted cement pore solution, where cement particles are excluded, and in cement mixture was observed. The observed contrast was attributed to the chemical processes between the hydrogel and cement particles, which are......
Membrane action, deflections and cracking of two-way reinforced concrete slabs
Matériaux et constructions - Tập 10 - Trang 303-312 - 1977
The paper presents a brief and critical review of some major studies on two-way reinforced concrete slabs concerning the application of membrane analysis for the prediction of ultimate loads, determination of deflections and crack widths.
Interaction between tensile strength failure and mixed mode crack propagation in concrete

Characterization and comparison of capillary pore structures of digital cement pastes
Matériaux et constructions - Tập 50 - Trang 1-12 - 2017
More and more studies are based on digital microstructures of cement pastes obtained either by numerical modelling or by experiments. A comprehensive understanding of the their pore structures, therefore, becomes significant. In this study, the pore structure of a virtual cement paste (HYMO-1d) generated by cement hydration model HYMOSTRUC 3D is characterized. The pore structure of HYMO-1d is comp......
Analysis of interactions between damage and basic creep of HPC and HPFRC heated between 20 and 80 °C
Matériaux et constructions - Tập 46 Số 1-2 - Trang 13-23 - 2013
Indirect determination of size effect on strength of asphalt mixtures at low temperatures
Matériaux et constructions - Tập 47 - Trang 157-169 - 2013
Low temperature cracking of asphalt pavements is a major distress in cold regions. Accurate assessment of strength of asphalt mixtures at low temperatures is of great importance for ensuring the structural integrity of asphalt pavements. It has been shown that asphalt mixtures behave in a quasibrittle manner at low temperatures and consequently its nominal strength strongly depends on the structur......
Études sur l’efficacité et la durabilité de deux traitements appliqués à un calcaire
Matériaux et constructions - Tập 19 - Trang 279-283 - 1986
Ce travail présente une étude en laboratoire sur l’efficacité et la durabilité de deux produits de traitement des pierres: un hydrofuge de surface (à base de résine silicone) et un produit de protection superficielle contre les agents atmosphériques et la pollution (qui se compose d’un polymère acrylique, d’un solvant et d’une cire synthétique). La pierre étudiée était un calcaire d’Ançã, très uti......
