Bronze-Phase TiO2 as Anode Materials in Lithium and Sodium-Ion Batteries

Titanium dioxide of bronze phase (TiO2(B)) has attracted considerable attention as a promising alternative lithium/sodium-ion battery anode due to its excellent operation safety, good reversible capacity, and environmental friendliness. However, several in ...

Hydration and durability of fast hardening binders incorporating supplementary cementitious materials

Sarra El Housseini

The use of supplementary cementitious materials (SCMs) is widely considered the most promis-ing approach to reduce CO2 emissions relative to cement production. SCMs are not commonly present in binders used for special applications. On the other hand, due t ...

Maximizing the use of supplementary cementitious materials (SCMs) in blended cements

Yosra Briki

Partial replacement of clinker with supplementary cementitious materials (SCMs) is an effective approach to reduce CO2 emissions related to cement production. However, there is a maximum substitution level with SCMs beyond which strength decreases. The und ...

Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking

Tomás Alfredo Trewhela Palacios, Carmela Lardo

Context. Extended main sequence turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where the main sequence turn-off is broader than can be explained by photome ...

Reaction Degree of Metakaolin in Limestone Calcined Clay Cement (LC3)

Karen Scrivener, François Henri Avet

The amount of reacted metakaolin is determined using two methods: mass balance and thermodynamic modeling. It is found that mass balance is the most promising method. Thermodynamic modeling gives slightly underestimated results at late ages. ...

Development of physical and mechanical properties of a cold-curing structural adhesive in a dry bridge environment

Thomas Keller, Anastasios Vassilopoulos, Maria Savvilotidou

The effect of physical aging and continuation of curing on the physical and mechanical properties of a commercial cold-curing structural epoxy adhesive used in bridge construction has been investigated during the first year. Since adhesive bridge joints ar ...

From weak signals to mobility scenarios: A prospective study of France in 2050

Vincent Kaufmann, Emmanuel Pierre Jean Ravalet

Prospective analyses, be they in the field of transport or other areas, are generally developed based on a retrospective of the preceding decades. The trends highlighted are then followed, changed, brought out, accentuated, etc. However, a recent look at m ...

Effect of fineness in clinker-calcined clays-limestone cements

Karen Scrivener, Mathieu Antoni, Adrian Alujas Diaz, Leng Maday Vizcaino Andres

This paper looks at the effect of fineness of the different components in a blend containing 55% Portland cement, 30% calcined clay and 15% limestone. The calcined clay originates from a natural deposit in Cuba and contains less than 50% kaolinite. The par ...
