Investigation of the effect of mineral dissolution on the geomechanical behaviour of geomaterials

Taeheon Kim

Geotechnical engineering scenarios engaged in internal erosion or mineral dissolution were found worldwide, from CO2 sequestration projects to internal erosion of earth dams. Materials subjected to loss of solid phase from their internal fabric vary from s ...

Understanding of the factors slowing down metakaolin reaction in limestone calcined clay cement (LC3) at late ages

Karen Scrivener, Paul Bowen, Mohsen Ben Haha, François Henri Avet, Yosra Briki

Factors which could explain the slowing down of the metakaolin reaction in LC3 blends are investigated. Portlandite availability and the presence of aluminium ions in the pore solution are shown not to be limiting factors. ...

Aggregate dissolution in different pore solutions

Mahsa Bagheri

The occurrence of cracking due to alkali silica reaction (ASR) affects the service life of concrete structures. The dissolution of silica-containing minerals within aggregates causes the formation of ASR products, which fill macroscopic cracks and cause th ...

Quantification methods for chloride binding in Portland cement and limestone systems

Wei Sun, Karen Scrivener, Fabien Jacques Michel Georget, Hamed Maraghechi, William Wilson, Shiyu Sui

This paper presents a comparison of methods to quantify the chloride binding capacity for cementitious materials composed of Ordinary Portland Cement (OPC) and Limestone (LS, 0 to 55% replacement). Physical and chemical chloride bindings were investigated ...

Anisotropic Volumetric Response of Shales upon Suction Changes

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Anisotropic fabric and volumetric response to suction changes represent two main features of shales, which are involved in several engineering applications. However, a comprehensive understanding of the interaction between these two aspects is still missin ...

Coupled Approach to Assess Caprock Deformation Caused by CO2 Injection

Lyesse Laloui, Chao Li

This study focuses on a specific problem related to the caprock deformation induced by the injection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and t ...

Coupled semi-analytical solution for CO2 injection-induced surface uplift and caprock deflection

Lyesse Laloui, Chao Li

This study focuses on a specific problem related to the surface uplift induced by the injection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and the fl ...

Anisotropic features of the mechanical behaviour of Opalinus clay

Lyesse Laloui, Mathieu Nuth, Simon Salager

The Opalinus Clay is a potential host rock for radioactive waste repositories. Triaxial tests at different load levels and directions carried out on Opalinus clay showed that the mechanical behaviour of this soft rock is anisotropic. The stiffer samples ar ...
