Recent studies of cements and concretes by synchrotron radiation crystallographic and cognate methods
(Taylon & Francis, 2015)
The portfolio of available synchrotron radiation techniques is increasing notably for cements
and pastes. Furthermore, sometimes the terminology is confusing and an overall picture highlighting
similarities and differences ...
Structure of stratlingite and effect of hydration methodology on microstructure
(ICE publishing, 2015)
Stratlingite, Ca4Al2(OH)12[AlSi(OH)8]2•2H2O, is an AFm phase which appears as hydration product of aluminum-rich cements. These binders may be calcium aluminate cements, calcium sulfoaluminate cements and also Belite Calcium ...
Synchrotron radiation: science & applications
(2015-03-23)
This general talk is devoted to briefly introduce the main uses and applications of synchrotron radiation. An initial introduction will be dedicated to describe a synchrotron as a Large Facility devoted to produce photons ...
Powder diffraction at ALBA synchrotron
(2015-03-23)
This talk is devoted to explain the uses of powder diffraction at MSPD (material science and powder diffraction) of ALBA synchrotron light source. General characteristics of the beamline are: Station 1 - High Pressure ...
ALBA Synchrotron Light Source
(2015-03-23)
ALBA synchrotron light source (www.cells.es) is the largest Spanish research infrastructure that started full operation of its first 7 beamlines on February 2013. I will divide the talk in three parts: i) the general ...
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 ...
Hydration of C4AF in the presence of other phases: A synchrotron X-ray powder diffraction study
(Elsevier, 2015)
Hydration behaviour of C4AF in selected experimental conditions has been determined. C4AF has been
hydrated in the absence and presence of gypsum, two polymorphs of ye’elimite and different water/solid
ratios. C4AF in ...
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 ...
Proton conductivity of multifunctional metal phosphonate frameworks
(2015-03-23)
Metal phosphonates exhibit attractive characteristics for proton conductivity, such as tunable functionality, chemical and thermal stability and the existence of H-bond networks with acidic protons within their structure.1
In ...
Processing and characterisation of Calcium SulfoAluminate (CSA) eco-cements coated with a hybrid organo-inorganic material for photocatalytic applications
(2015-07-27)
On the one hand, Calcium SulfoAluminate (CSA) eco-cements are receiving increasing attention since their manufacture produces up to 40% less CO2 than ordinary Portland cement (OPC). In addition, they show interesting ...
