Clinkering and hydration of belite-ye'elimite-alite cement
(Elsevier, 2017)
Some belite-ye´elimite-ferrite (BYF) cements present low mechanical strengths mainly due to the slow reactivity of belite. A solution to this problem may be the activation of BYF clinkers by preparing them with a coexistence ...
Tailored setting times with high compressive strengths in bassanite calcium sulfoaluminate eco-cements
(Elsevier, 2016-09)
This work deals with the hydration of a calcium sulfoaluminate (CSA) eco-cement prepared with bassanite and different additives (type and content) at a fixed water/CSA ratio of 0.5. Pastes prepared with bassanite show high ...
Hydration of Belite-Ye’elimite-Ferrite(BYF) cements with different calcium sulfate sources
(ICE publishing, 2016-07)
Belite-Ye’elimite-Ferrite cements, BYF, are a sustainable alternative to OPC to reduce CO2 emissions. The aim of this research is to understand the influence of the sulfate source on the hydration of two laboratory-prepared ...
Aluminum-rich belite sulfoaluminate cements: clinkering and early age hydration
(Elsevier, 2009)
Belite sulfoaluminate (BSA) cements have been proposed as environmentally friendly building
materials, as their production may release up to 35% less CO2 into the atmosphere when compared
to ordinary Portland cements. ...
Effects of sulfates on the hydration of Portland cement – A review
(2021)
Presented within is a critical overview of the effect of sulfates on cement hydration, properties, and optimum
sulfate content in Portland cement. Calcium sulfate is used in Portland cement to control the C3A
reaction ...
Reactivity of C3S and model cement in presence of Na2S2O3 and NaSCN
(Springer, 2023-01)
The impact of NaSCN and Na2S2O3 on the reactivity, microstructure and morphology of C3S and
model cement (with a clinker containing 85% C3S and 15% C3A) pastes was systematically investigated.
Results concluded that both ...
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 ...
The effects of MgO, Na2O and SO3 on industrial clinkering process: phase composition, polymorphism, microstructure and hydration, using a multidisciplinary approach
(2019-07-02)
The present investigation deals with how minor elements (their oxides: MgO, Na2O and SO3) in industrial kiln
feeds affect (i) chemical reactions upon clinkering, (ii) resulting phase composition and microstructure ...
The role of sodium and sulfate sources on the rheology and hydration of C3A polymorphs
(Elsevier, 2022)
The higher reactivity of orthorhombic C3A (ort-C3A) in sulfate-containing solutions, compared with cubic C3A (cb-C3A), was previously related to the differences in crystal structure or the sodium in the ort-C3A pore solution. ...
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 ...
