X-ray diffraction, cements and environment, three worlds in one
(2017-12-13)
This keynote lecture will be focused on the strategies for reducing CO2 emissions in the cement production. Concretely, the production of ecocements with optimised formulations that yield reductions in CO2 emissions of up ...
Activation of LC3 binders by C-S-H nucleation seeding with a new tailored admixture for low-carbon cements.
(Ernst & Sohn GmbH, 2023-12-06)
The use of supplementary cementitious materials is currently the most favorable
strategy for reducing CO2 emissions in cements. Limestone Calcined Clay Cements,
LC3, are a type of cement that allows the reduction of CO2 ...
Effect of boron and water-to-cement ratio on the performances of laboratory prepared Belite-Ye'elimite-Ferrite (BYF) cements
(2021)
The effect of superplasticiser, borax and the water-to-cement ratio on BYF hydration and
mechanical strengths has been studied. Two laboratory-scale BYF cements—st-BYF (with -C2S
and orthorhombic C4A3 S) and borax-activated ...
Clinkering of calcium sulfoaluminate clinkers: polymorphism of ye'elimite
(2018)
The manufacture of CSA cements is more environmentally friendly than that of OPC as it releases
less CO2. This reduction depends on CSA composition and is due to three factors: i) less emissions
from decarbonation in the ...
Limestone calcined clay binders based on a Belite-rich cement
(Elsevier, 2023)
Portland-based Limestone Calcined Clay Cements, LC3, are receiving considerable attention because the CO2 footprint can be reduced up to 40 %. Here, we report a related family: Belite-rich-LC3. These blends are expected ...
Hydration Activation of Alite-Belite-Ye’elimite Cements by Doping with Boron
(2020)
The hydration behavior of two alite-belite-ye’elimite (ABY)
cements has been studied. The production of these materials releases into
atmosphere ∼17% less CO2 compared to Portland cement. The ABY cement
contains alite, ...
Early hydration study of standard and doped Alite-Belite-Ye’elimite (ABY) cements through Synchrotron Radiation
(2018-07-09)
The manufacturing of ye'elimite-rich cements releases from 15 to 37%, depending on their
composition, less CO2 to the atmosphere than ordinary Portland cement (OPC). BYF cements
containing belite, ye’elimite and ferrite ...
Influence of fly ash blending on hydration and physical behavior of Belite-Alite-Ye'elimite cements
(2018-10-19)
A cement powder, composed of belite, alite and ye’elimite, was blended with 0, 15 and 30 wt% of fly ash and the resulting lended cements were further characterized. During hydration, the presence of fly ash caused the ...
Rietveld quantitative phase analysis of Yeelimite-containing cements
(Elsevier, 2012-03-26)
Yeelimite-containing cements are attracting attention for their tailored properties. Calcium sulfoaluminate,
CSA, cements have high contents of Yeelimite and they are used for special applications. Belite calcium
sulfoaluminate, ...
Hydration studies of calcium sulfoaluminate cements blended with fly ash
(Elsevier, 2013)
The main objective of this work is to study the hydration and properties of calciumsulfoaluminate cement pastes
blended with fly ash (FA) and the corresponding mortars at different hydration ages. Laboratory X-ray ...
