Shear behavior of single- and triple-thickness masonry panels strengthened by bed-joint structural repointing

Bed-joint structural repointing is a widely used strengthening technique in historic masonry constructions, particularly in applications where the material appearance needs to be preserved. Despite its wide use, limited research is available on the effecti ...

Strength-promoting mechanism of alkanolamines on limestone-calcined clay cement and the role of sulfate

Karen Scrivener, François Henri Avet, Xuerun Li, Wilasinee Hanpongpun, Hong Huang

This paper reports the strength-promoting mechanism of alkanolamines on limestone-calcined clay cement (LC3). The hydration kinetics, phase formation and microstructure of LC3 with triethanolamine (TEA) or triisopropanolamine (TIPA) were investigated. TEA ...

Multi-scale modelling of concrete structures affected by alkali-silica reaction: Coupling the mesoscopic damage evolution and the macroscopic concrete deterioration

Jean-François Molinari, Emil Gallyamov, Mauro Corrado, Roozbeh Rezakhani, Aurelia Isabel Cuba Ramos

A finite-element approach based on the first-order FE2 homogenisation technique is formulated to analyse the alkali-silica reaction-induced damage in concrete structures, by linking the concrete degradation at the macro-scale to the reaction extent at the ...

Characterization of interfacial transition zone in concrete prepared with carbonated modeled recycled concrete aggregates

Karen Scrivener

Treatment by accelerated carbonation has been widely studied to enhance the quality of recycled concrete aggregates (RCA) and hence the performance of new concrete produced with the RCA. This is often ascribed to the densification of RCA. This study invest ...

Hydration reactions and stages of clinker composed mainly of stoichiometric ye'elimite

Karen Scrivener, Emmanuelle Boehm Courjault, Mohsen Ben Haha, Frank Bullerjahn

Ye'climitc (Ca4Al6O12SO4 or C(4)A(3)(S) over bar) is the main hydraulic mineral present in calcium sulfoaluminate cement (CSA). The hydration of ye'elimite is responsible for the early age cement properties. We identify 5 stages in the hydration of neat st ...

Simplified micro-modelling of shear-compression stone masonry walls and their interaction with plaster

Katrin Beyer, Bastian Valentin Wilding, Michele Godio, Dionysia Michalogianni

The performance of shear-compression stone masonry walls with regard to their interaction with plaster is investigated by means of numerical simulations. A 3D finite element model based on the simplified micro-modelling technique is developed for the mason ...

A 2D typology generator for historical masonry elements

Katrin Beyer, Shenghan Zhang, Martin Hofmann

The mechanical response of stone masonry depends on the properties of the components and also on the typology created by the stone units and the mortar joints. While the influence of the component strength on masonry is relatively well studied, few studies ...

Evaluation of grout materials for CFRP ground anchors with strap ends

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

An evaluation of cement- and resin-based grout materials for applications in carbon fiber-reinforced polymer (CFRP) ground anchor heads composed of high-strength grout and a CFRP strap was conducted. Uniaxial compression experiments were performed on cylin ...
