Basic creep of limestone-calcined clay cements: An experimental and numerical approach

This article presents a study on the creep properties of limestone calcined clay cement. A series of paste samples using limestone and calcined clays as replacement materials were tested under basic compressive creep. The ternary mixes showed a lower creep ...

Impacting factors and properties of limestone calcined clay cements (LC3)

Karen Scrivener, Franco Alberto Zunino Sommariva, François Henri Avet, Julien Ston, Aurélie Rosine Favier, Hamed Maraghechi, Wilasinee Hanpongpun

This paper details the main factors influencing the performance of limestone calcined clay cements (LC3). The kaolinite content plays a major role in the rheological properties as well as strength development. Even in the presence of secondary phases, kaol ...

A semi-automated quantitative CT method for measuring rotator cuff muscle degeneration in shoulders with primary osteoarthritis

Alexandre Terrier, Alain Farron, Julien Ston, Antoine Dewarrat

Background: Rotator cuff muscle degeneration is an important parameter to consider when planning shoulder arthroplasty. Hypothesis: We hypothesized that rotator cuff muscle degeneration is correlated with scapulohumeral subluxation in patients planned for ...

Intrinsic viscoelasticity of C-S-H assessed from basic creep of cement pastes

Karen Scrivener, Julien Ston, Adrien Jean Régis Maurice Hilaire, Zhangli Hu

This paper investigates the fundamental mechanisms behind the effect of supplementary cementitious materials (SCMs) on the basic creep behavior of cement pastes. The intrinsic creep properties of the C-S-H gel are assessed based on measurements of uniaxial ...

Basic creep and autogenous shrinkage of Limestone Calcined Clay Cement (LC3)

Julien Ston

The use of supplementary cementitious materials (SCM) to lower the clinker factor of cements is now commonplace, for it benefits performance, economics and ecology. This thesis focuses on ternary blends of limestone and calcined kaolinitic clays, two very ...

Measurements of three-dimensional glenoid erosion when planning the prosthetic replacement of osteoarthritic shoulders

Alexandre Terrier, Alain Farron, Julien Ston, Xabier Larrea

The three-dimensional (3D) correction of glenoid erosion is critical to the long-term success of total shoulder replacement (TSR). In order to characterise the 3D morphology of eroded glenoid surfaces, we looked for a set of morphological parameters useful ...

Does locally delivered Zoledronate influence peri-implant bone formation? – Spatio-temporal monitoring of bone remodeling in vivo

Dominique Pioletti, Ulrike Kettenberger, Julien Ston

Bisphosphonates are known for their strong inhibitory effect on bone resorption. Their influence on bone formation however is less clear. In this study we investigated the spatio-temporal effect of locally delivered Zoledronate on peri-implant bone formati ...

Importance of a three-dimensional measure of humeral head subluxation in osteoarthritic shoulders

Alexandre Terrier, Alain Farron, Julien Ston

Hypothesis: During total shoulder arthroplasty (TSA), humeral head subluxation may be difficult to manage. Furthermore, there is a risk for postoperative recurrence of subluxation, affecting the outcome of TSA. An accurate evaluation of the subluxation is ...

Autogenous Shrinkage and Creep of Limestone and Calcined Clay Based Binders

Karen Scrivener, Julien Ston, Adrien Jean Régis Maurice Hilaire

This study explored the delayed strains in limestone and calcined clay ternary blends. Autogenous shrinkage measurements are carried out over 2 months and compressive basic creep tests during 28 days after one month of curing. All tests are done using mixe ...
