Atomic-Level Structure and Thermodynamic and Kinetic Modelling of Zinc-Modified C-S-H
The most promising solution towards cementitious materials with a lower carbon footprint is the partial substitution of the clinker by supplementary cementitious materials (SCMs) such as fly ash, blast furnace slag, limestone and calcined clays. The produc ...
EPFL2023Nanoscale modelling of ionic transport in the porous C-S-H network
To reduce the CO2 footprint of construction materials, concrete producers blend their cement with Supplementary Cementitious Materials (SCMs). SCMs such as fly ash or blast furnace slag are mostly the byproducts of other industries. And while SCMs are chos ...
EPFL2022Resistance of cementitious materials to sulfate attack: quantifying performance with a reliable unidirectional approach
Depending on the environmental conditions, concrete materials can come into contact with sulfate ions which are widely present in rivers, underground water, sewers, seawater and soil. Sulfates can react with the cement paste in concrete and cause damage wh ...
EPFL2022Reactive dicalcium silicate binders: Microstructure and transport properties
The calcium silicate hydrates (C-S-H) are without doubt one of the most important hydration products in a hardened cement paste. Giving the complexity of the microstructure that forms by hydration of ordinary Portland cement (OPC) and the more recently use ...
EPFL2022Hydration and durability of fast hardening binders incorporating supplementary cementitious materials
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 ...
EPFL2022The effect of alkali hydroxides and equilibration time on Al uptake by calcium silicate hydrates (C-S-H)
Cement production accounts for approximately 8% of man-made CO2 emissions. Lowering these CO2 emissions is currently one of the most important and urgent research topics within the cement community. To reduce these emissions, the Portland cement (PC) is pa ...
EPFL2021Towards tailored cement-based materials with ground calcium carbonates
Emmanuel Denarié, Lionel Sofia
Proportioning the dosage of Ground Calcium Carbonates (GCC) in cementitious materials, beyond current normative levels, is one of the most promising ways towards sustainability of mortar and concrete technology. Performance parameters such as the water/bin ...
2021Maximizing the use of supplementary cementitious materials (SCMs) in blended cements
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 ...
EPFL2020Characterization of interfacial transition zone in concrete prepared with carbonated modeled recycled concrete aggregates
Treatment by accelerated carbonation has been widely studied to enhance the quality of recycled concrete aggregates (RCA) and hence the performance of new concrete produced with the RCA. This is often ascribed to the densification of RCA. This study invest ...
PERGAMON-ELSEVIER SCIENCE LTD2020Carbonation of low carbon binders
To reduce the impact of the embodied energy and of the carbon dioxide emissions of concrete, the use of supplementary cementitious materials (SCMs) in the cement industry has become a common practice. However, the practical experience on such cements is li ...
