Rheological and hydration characterization of calcium sulfoaluminate cement pastes
(2015-05-14)
Calcium sulfoaluminate (CSA) cements are currently receiving a lot of attention because their manufacture produces less CO2 than ordinary Portland cement (OPC). However, it is essential to
understand all parameters which ...
Combined use of laboratory X-ray diffraction and microtomography in early age cement hydration.
(2023)
In situ laboratory X-ray powder diffraction (LXRPD) is widely used for studying cement hydration at
early ages. However, this approach has limitations due to the intrinsic characteristics of the main
methodologies (flat ...
Activation of LC3 binders by C-S-H nucleation seeding with a new tailored admixture for low-carbon cements.
(2023)
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 ...
Belite calcium sulfoaluminate cement early hydration: citric acid sensitivity.
(2023)
Three buckets, corresponding to three selected samples, of the same type of belite calcium sulfoaluminate (BCSA) cements have been studied. These cements show very similar elemental and mineralogical compositions, and ...
Effect of alkanolamines in kaolinitic calcined clays pozzolanic reactivity.
(2023)
Five kaolinitic clays with different amounts of kaolinite, ranging between ~70 wt% and ~30 wt%, have
been studied to unravel the possible activation effect of alkanolamines on the aluminate fraction of
calcined clays. ...
Clinkering and early age hydration characterization of Belite-Alite Calcium Sulfoaluminate (BACSA) cements
(2015-10-26)
In this work, four BACSA clinkers with different compositions (belite ~ 70-55 wt %, alite ~ 10-15 wt % and ye’elimite ~ 10-15 wt %) were synthesized (at laboratory scale). Lime, gypsum, kaolin and sand were used as raw ...
Synthesis and scaled-up of non-active and active Belite-Alite-Ye'elimite clinker (BAY)
(2017-05-17)
Ordinary Portland cement (OPC) is an environmentally contentious material, as for every ton of OPC produced, ~0.97 tons of CO2 are released. This opens the need of designing new formulations of cements formed by low calcite ...
Hydration study of alite-ye’elimite-anhydrite phases associated to BAY cement
(2017-10-18)
An alternative to decrease CO2 emissions from OPC production consists on the development of a new kind of eco-cements composed by less calcite demanding phases, such as belite and ye'elimite. That is the case of ...

Effect of different retarders on the hydration of calcium sulfoaluminate eco-cement pastes
(2014-07-09)
The manufacture of Calcium SulfoAluminate (CSA) cements is more environmentally friendly than that of OPC [1] as their production releases up to 40% less CO2 than the latter. The main performances of CSA cements are fast ...
