Chemistry and Mass Density of Aluminum Hydroxide Gel in Eco- Cements by Ptychographic X‑ray Computed Tomography
<p>Raw data for: Chemistry and Mass Density of Aluminum Hydroxide Gel in Eco- Cements by Ptychographic X‑ray Computed Tomography </p> <p>doi: http://dx.doi.org/10.1021/acs.jpcc.6b10048</p> <p> </p> <p>Eco-cements are a desirable alternative to ordinary Portland cements because of their lower CO<sub>2</sub> footprints. Ye'elimite-based eco-cements are attracting a lot of interest but most of them exhibit relatively poor mechanical properties. Understanding the reasons for the low performances requires the characterization of features such as mass density of the hydrated mineralogical phases, including the amorphous gel, on the sub-micrometer scale which is very challenging. Here we use ptychographic X-ray computed tomography to provide 3D mass density and attenuation coefficient distributions of eco-cement pastes with an isotropic resolution close to 100 nm allowing to distinguish between mineralogical phases with very similar contrast. In combination with laboratory techniques such as the Rietveld method, <sup>27</sup>Al MAS-NMR and electron microscopies, we report compositions and densities of key components. The ettringite and gel volume distributions have been mapped out in the segmented tomograms. Moreover, we discriminate between an aluminum hydroxide gel and calcium aluminum monosulfate, which have close electron density values. Specifically, the composition and mass density of two aluminum hydroxide gels have been determined: (CaO)<sub>0.04</sub>Al(OH)<sub>3</sub>·2.3H2O with 1.48(3) g∙cm<sup>-3</sup> and (CaO)<sub>0.12</sub>Al(OH)<sub>3</sub> with 2.05(3) g∙cm<sup>-3</sup>, which was a long standing challenge.</p>
