Portland and belite cement hydration acceleration by C-S-H seeds with variable w/c ratios
(Materials, 2022)
The acceleration of very early age cement hydration by C-S-H seeding is getting attention from scholars and field applications because the enhanced early age features do not compromise later age performances. This acceleration ...
Belite hydration at high temperature and pressure by in situ synchrotron powder diffraction
(2020-10-16)
Portland cements are currently used as Oil‐Well‐Cements for the sheath between the metal casing
and the borehole. At high pressures and temperatures, the resulting C-S-H gel(s) is partly unstable
and it can react to give ...
High pressure and temperature spinning capillary cell for in-situ synchrotron X-ray powder diffraction
(2019)
In situ research of materials under moderate pressures (hundreds of bar) is essential in many scientific fields. These range from gas sorption to chemical and biological processes. One industrially important discipline is ...
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 ...
Recent Advances in C-S-H Nucleation Seeding for Improving Cement Performances
(MDPI, 2023)
Reducing cement CO2 footprint is a societal need. This is being achieved mainly by replacing
an increasing amount of Portland clinker by supplementary cementitious materials. However,
this comes at a price: lower mechanical ...
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, ...
Reactive belite stabilization mechanisms by boron-bearing dopants
(Elselvier, 2012-01-27)
Belite-rich cements hold promise for reduced energy consumption and CO2 emissions, but their use is hindered
by the slow hydration rates of ordinary belites. This drawback may be overcome by activation of belite
by doping. ...
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 ...
