Numerical Simulation of Porosity in Cements

Karen Scrivener, Shashank Bishnoi, Quang Huy Do

The pores in cementitious materials, their sizes and connectivity have an important influence on the durability of concrete. Several microstructural models have been developed to simulate the three-dimensional pore network in cement pastes. In this article ...

Cement distribution in vertebroplasties: imaging and simulation

Vincent Stadelmann

Prophylactic vertebroplasty, the percutaneous injection of bone cement into a weak vertebral body (VB), has been shown to reinforce the bone and possibly to minimize fracture risks. Cement leakage is still a common occurrence that can cause severe complica ...

Alkali fixation of C-S-H in blended cement pastes and its relation to alkali silica reaction

Karen Scrivener, Theodor Alexandre Emmanuele Chappex

Supplementary cementitious materials (SCM) are known to reduce or even stop expansion due to alkali silica reaction (ASR) in concretes with reactive aggregates. Studies indicate that the main reason for this is the decrease in alkalinity of the pore soluti ...

Injectable calcium phosphate cement for augmentation around cancellous bone screws. In vivo biomechanical studies

Dominique Pioletti, Vincent Stadelmann

In lower cancellous apparent bone density, it can be difficult to achieve adequate screw fixation and hence stable fracture fixation. Different strategies have been proposed, one of them is through augmentation using calcium phosphate cement in the region ...

Lattice Boltzmann simulations of the permeability and capillary adsorption of cement model microstructures

Mohamad Zalzale

The lattice Boltzmann method is used to investigate the permeability of microstructures of cement pastes generated using the numerical models CEMHYD3D (Bentz, 1997) and mu IC (Bishnoi and Scrivener, 2009). Results are reported as a function of paste water- ...

Cement substitution by a combination of metakaolin and limestone

Karen Scrivener, Mathieu Antoni, John Espen Rossen

This study investigates the coupled substitution of metakaolin and limestone in Portland cement (PC). The mechanical properties were studied in mortars and the microstructural development in pastes by X-ray diffraction, thermogravimetry analysis, mercury i ...

Limestone Addition in Cement

Olga Agata Chowaniec

Addition of fine limestone provides an excellent means to reduce the amount of clinker in cement. It is now well accepted that limestone partially reacts in cementitious systems with C3A to produce hemi- and monocarboaluminate phases and as a consequence m ...

The role of aluminium from supplementary cementitious materials in controlling alkali-silica reaction

Theodor Alexandre Emmanuele Chappex

Alkali silica reaction (ASR) is a long-term reaction between certain aggregates containing amorphous silicate phases and the alkalis from the cement paste. These silicates react with the alkalis present in the pore solution of the cement paste and form an ...

Importance of polyethylene thickness in total shoulder arthroplasty: A finite element analysis

Dominique Pioletti, Alexandre Terrier, Alain Farron, Vittoria Brighenti

Background: Articular surfaces reconstruction is essential in total shoulder arthroplasty. Because of the limited glenoid bone support, thin glenoid component could improve anatomical reconstruction, but adverse mechanical effects might appear. Methods: Wi ...

Compositions and methods for well treatment

Brice Tanguy Alphonse Lecampion

A self-healing cement for use in wells in which carbon dioxide is injected, stored or extracted, comprises a carbonaceous material. In the event of cement-matrix failure, or bonding failure between the cement/casing interface or the cement/borehole-wall in ...
