Influence of Low- to Medium-Kaolinite Clay on the Durability of Limestone Calcined Clay Cement (LC3) Concrete
The kaolinite content is principally responsible for the durability performance of Limestone Calcined Clay Cement (LC3), which calls into question its global applicability. The clay supply has a significant impact on the LC3 system's reduced carbon footpri ...
MDPI2023Data-driven numerical site response
Jean-François Molinari, Antonio Joaquin Garcia Suarez, Sacha Zenon Wattel
Prediction of ground motion triggered by earthquakes is a prime concern for both the seismology community and geotechnical earthquake engineering one. The subfield occupied with such a problem is termed site response analysis (SRA), its one-dimensional fla ...
2022Increasing the kaolinite content of raw clays using particle classification techniques for use as supplementary cementitious materials
Karen Scrivener, Franco Alberto Zunino Sommariva
The adoption of blended cements to reduce the carbon footprint has increased significantly over the last decades. Clays containing kaolinite are a promising choice due to their widespread availability. Kaolinite content is the major factor controlling the ...
ELSEVIER SCI LTD2020Phyllomanganate vein-infillings in faulted and Al-poor regoliths of the New Caledonian ophiolite: periodic and sequential crystallization of Ni-asbolane, Alk-birnessite and H-birnessite
Mineralogy, chemistry and spatial distribution of phyllomanganates, found in abundance at the bottom of thick Ni-laterite deposits, were established on dislocated vein-infillings showing banded and fibrous patterns (i.e. colloforms with rows of tiny boxwor ...
2019An experimental investigation on the water retention behaviour of a silty soil for the computation of the lateral earth thrust on a retaining wall
Lyesse Laloui, Alessio Ferrari, Gianluca Speranza
Retaining structures often interact with soils in unsaturated conditions and their performance is influenced by environmental actions. Currently, geotechnical analysis and design approaches mainly consider the soils either totally dry or totally saturated. ...
E3S Web of Conferences2019Vertical changes of the Co and Mn speciation along a lateritic regolith developed on peridotites (New Caledonia)
Gabrielle Dublet, Vincent Noel
Because they can host significant amounts of Co, the Mn-oxides are commonly considered as the major Co-bearing mineral species in lateritic environments. However, little is known about the process leading to the formation and/or the weathering of these Co- ...
Pergamon-Elsevier Science Ltd2017The Effect of Mg on Slag Reactivity in Blended Cements
Karen Scrivener, Ruben Anton Snellings
Blast-furnace slags are widely used as supplementary cementitious materials in blended cements because of their relatively high reactivity. This study describes the effect of substituting Ca by Mg on the reactivity of synthetic glass with similar compositi ...
Springer2014Depletion of Stem Water of Sclerocarya birrea Agroforestry Tree Precedes Start of Rainy Season in West African Sudanian Zone
Marc Parlange, Natalie Claire Ceperley, Theophile Mande
Understanding water use by agroforestry trees in dry-land ecosystems is essential for improving water management. Agroforestry trees are valued and promoted for many of their ecologic and economic benefits but are often criticized as competing for valuable ...
2013Decoupling Feature Size and Functionality in Solution-Processed, Porous Hematite Electrodes for Solar Water Splitting
Kevin Sivula, Jérémie Minh-Châu Brillet
We introduce a simple solution-based strategy to decouple morphological and functional effects of annealing nanostructured, porous electrodes by encapsulation with a SiO2 confinement scaffold before high temperature treatment We demonstrate the effectivene ...
American Chemical Society2010Rare earth elements in groundwater from different Alpine aquifers
Aurèle Parriaux, Michaël Bensimon
Rare earth elements (REE) were determined in 39 groundwater samples collected at 14 sites under low- and high-flow conditions. Water samples derived from aquifers hosted in crystalline, molasse, flysch, carbonate and evaporite rocks located in Western Swit ...
