Hydration characteristics and mechanical performances of LC3 binders with spanish kaolinitic calcined clays
(2022)
Limestone Calcined Clay Cements (LC3) are binders with complex phase development and
microstructures. Although the hydration chemistry of these cements are being widely researched [1],
due to the clay mineralogy variability, ...
High-Throughput Synthesis of Pillared-Layered Magnesium Tetraphosphonate Coordination Polymers: Framework Interconversions and Proton Conductivity Studies
(MDPI, www.mdpi.com/journal/inorganics, 2018-09-11)
Novel pillared-layered framework materials were synthesized by high-throughput
or microwave-assisted methodology that contain Mg2+ and the zwitterionic linker HDTMP
(hexamethylenediamine-N,N,N0,N0-tetrakis(methylenephosphonic ...
Structural Variability in Multifunctional Metal Xylenediaminetetraphosphonate Hybrids
(American Chemical Society, 2013-07-24)
Two new families of divalent metal hybrid derivatives from the aromatic tetraphosphonic acids 1,4- and 1,3-bis(aminomethyl)benzene-N,N′-bis(methylenephosphonic acid), (H2O3PCH2)2−N−CH2C6H4CH2−N(CH2PO3H2)2 (designated herein ...
Tuning Proton Conductivity in Alkali Metal Phosphonocarboxylates by Cation Size-Induced and Water-Facilitated Proton Transfer Pathways
(American Chemical Society, 2014-12-20)
The structural and functional chemistry of a family of alkali-metal ions with racemic R,S-hydroxyphosphonoacetate (M-HPAA; M = Li, Na, K, Cs) are reported. Crystal structures were determined by X-ray data (Li+, powder ...
2D Corrugated Magnesium Carboxyphosphonate Materials: Topotactic Transformations and Interlayer “Decoration” with Ammonia
(American Chemical Society, 2012-06-29)
In this paper we report the synthesis and structural characterization of the 2D layered coordination polymer Mg(BPMGLY)(H2O)2 (BPMGLY = bis-phosphonomethylglycine, (HO3PCH2)2N(H)COO2−). The Mg ion is found in a slightly ...
Processing of calcium sulfoaluminate eco-cement coatings containing microencapsulated phase change materials.
(ICE Publishing, 2023-11-11)
On the one hand, calcium sulfoaluminate (CSA) eco-cements release about 40% less carbon dioxide (CO2) than Portland
cement during fabrication; on the other hand, phase change materials dispersed in a cementitious matrix ...
In situ hydration imaging study of a ye'elimite paste by ptychographic x-ray computed tomography
(2017)
Eco-cements are a desirable alternative to ordinary Portland cements because of their lower CO2 footprints. For instance, the manufacture of Calcium SulfoAluminate (CSA) cements is more environmentally friendly than that ...
Accuracy in Rietveld quantitative phase analysis: a comparative study of strictly monochromatic Mo and Cu radiations
(Willey online Library, 2016)
This study reports 78 Rietveld quantitative phase analyses using Cu K 1,
Mo K 1 and synchrotron radiations. Synchrotron powder diffraction has been
used to validate the most challenging analyses. From the results for ...
Chemistry and Mass Density of Aluminum Hydroxide Gel in Eco-Cements by Ptychographic X-ray Computed Tomography
(ACS, 2017)
Eco-cements are a desirable alternative to ordinary Portland
cements because of their lower CO2 footprints. Some ye’elimite-based ecocements
are attracting a lot of interest. Understanding the reasons for the
mechanical ...
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 ...
