“…However, the sonicated OPC has lower ion concentrations for the first two hours of hydration than the as-delivered OPC, and larger concentrations thereafter. The maximum concentration of Ca 2+ for the sonicated OPC was substantially higher than that reported in the literature, while the final value for the as-delivered OPC was less than would typically be expected 30,31 .…”

Pour obtenir de plus amples renseignements : http://lois.justice.gc.ca/fr/showtdm/cs/C-42 Growth of Cement Hydration Products on Single Walled Carbon Nanotubes AbstractSingle walled carbon nanotubes (SWCNT) were distributed on the surface of ordinary Portland cement (OPC) grains. The OPC/SWCNT composite was then hydrated at a 0.5 w/c ratio. The effects of the SWCNT on the early hydration process were studied using isothermal conduction calorimetry, high resolution scanning electron microscopy and thermogravimetric analysis. The observed behaviour of the composite samples was compared to both OPC sonicated without SWCNT and previously published data on as-delivered OPC. The SWCNT were found to accelerate the hydration reaction of the C 3 S in the OPC. The morphology of both the initial C 3 A and the C 3 S hydration products were found to be affected by the presence of the SWCNT. In particular, the nanotubes appeared to act as nucleating sites for the hydration products, with the nanotubes becoming rapidly coated with C-S-H. The resulting structures remained on the surface of the cement grains while those in the sonicated and as-delivered OPC samples grew out from the grain surfaces to form typical C-S-H clusters. Classical evidence of reinforcing behaviour, in the form of fiber pullout of the SWCNT bundles, was observed by 24 hours of hydration.

“…It has been stated that hollow shells or Hadley grains, as they also have been named after the man who first discovered them (David W Hadley [21]), seem not to form in C 3 S paste [24,28,29]. Of these authors, Pratt and Ghose [24] and Taylor et al [28] presented no experimental results to support this view.…”

Chemical and morphological characteristics of mineral trioxide aggregate and Portland cements

et al. 2016

The purpose of this study was to investigate the chemical composition and particle morphology of white mineral trioxide aggregate (WMTA) and two white Portland cements (CEM 1 and CEM 2). Compositional analysis was performed by energy dispersive X-ray spectroscopy, X-ray fluorescence spectrometry and X-ray diffraction whereas, morphological characteristics were analyzed by scanning electron microscope and Laser scattering particle size distribution analyzer. The elemental composition of WMTA, CEM 1 and CEM 2 were similar except for the presence of higher amounts of bismuth in WMTA. Calcium oxide and silicon oxide constitute the major portion of the three materials whereas, tricalcium silicate was detected as the major mineral phase. The particle size distribution and morphology of WMTA was finer compared to CEM 1 and CEM 2. The three tested materials had relatively similar chemical composition and irregular particle morphologies.
