Cell-free soil bio-cementation with strength, dilatancy and fabric characterization

A multi-disciplinary approach is adopted in the present work towards investigating bio-cemented geo-materials which extends from sample preparation, to microstructural inspection and mechanical behaviour characterization. We suggest a new way to induce “ce ...

Influence of calcium and magnesium carbonates on hydration kinetics, hydrate assemblage and microstructural development of metakaolin containing composite cements

Mohsen Ben Haha, Pawel Tadeusz Durdzinski

The hydration of metakaolin composite cements containing quartz, natural limestone and dolomite rock is studied using a multi-method approach and modelling. ...

Amorphous CaCO3: Influence of the Formation Time on Its Degree of Hydration and Stability

Camelia Borca, Francesco Stellacci, Huachuan Du, Esther Amstad, Anna Murello, Mathias Steinacher

Calcium carbonate (CaCO3) is one of the most abundant biominerals that is prevalent in rocks and often used as a structural material in marine animals. Many of these natural CaCO3-based materials display excellent mechanical properties that are difficult t ...

Effect of Ions and Admixtures on the Growth of Synthetic Calcium Silicate Hydrate (C-S-H)

Jirawan Siramanont

This thesis investigates the effect of different parameters such as Fe (III), D-gluconate and heterogeneous particles on the nucleation and growth of synthetic C-S-H by using the dropwise precipitation method. Firstly, the effect of Fe (III) on the synthet ...

Travertines associated with the Alhama-Jaraba thermal waters (NE, Spain): Genesis and geochemistry

Freshwater carbonates are interesting archives in palaeoenvironmental reconstructions. However, more studies of those systems are needed to fully understand past environments. In this work the actively-forming travertines of the Alhama-Jaraba thermal syste ...

Supercritical CO2 injection and residence time in fluid-saturated rocks: Evidence for CO2 and mineral dissolution and effects on rock integrity

Ke Liu, Lucas Xan Pimienta

CO2 injection and storage in geological reservoirs is an attractive prospect for mitigating the anthropogenic production of greenhouse gases and global warming. The technology could lead to mineral precipitation and therefore stable storage over geological ...

Phytoremediation of soils contaminated by organic compounds: hype, hope and facts

Jean-Paul Schwitzguebel

The present opinion paper is focused on the phytoremediation of organic pollutants and is based on the lectures given by the author during the International Congress of Phytoremediation of Polluted Soils, held at Vigo, Spain, 29-30 July 2014. The aim of th ...

Aragonitic scleractinian corals in the Cretaceous calcitic sea

Anders Meibom, Stéphane Laurent Escrig, Jaroslaw Hubert Stolarski

Changes in seawater chemistry have affected the evolution of calcifying marine organisms, including their skeletal polymorph (calcite versus aragonite), which is believed to have been strongly influenced by the Mg/Ca ratio at the time these animals first e ...

Dislocation Motion and the Microphysics of Flash Heating and Weakening of Faults during Earthquakes

Marie Estelle Solange Violay, Andrea Cavallo

Earthquakes are the result of slip along faults and are due to the decrease of rock frictional strength (dynamic weakening) with increasing slip and slip rate. Friction experiments simulating the abrupt accelerations (>>10 m/s(2)), slip rates (similar to 1 ...
