Three-dimensional Analysis of Cement-based Materials by Means of X-ray Tomographic Techniques
The knowledge of the microstructure of cement-based materials plays a fundamental role in predicting their macroscopic mechanical properties and durability. Nowadays, X-ray computed micro-tomography (X-μCT) provides a completely noninvasive tool for investigating, in a three-dime
Observation of dynamic crossover and dynamic heterogeneity in hydration water confined in aged cement paste
High resolution quasi-elastic neutron scattering is used to investigate the slow dynamics of hydration water confined in calcium silicate hydrate gel in an aged cement paste at supercooled temperatures. A super-Arrhenius to Arrhenius dynamic crossover of the average translational
A 3d Real-time Micromechanical Study of Bone-cement Interface
INTRODUCTION The lasting integrity of the bond between the bone and the cement is essential to the success and longevity of cemented total hip replacements [1]. It is well known how the strength of the bone-cement interface is related to the amount of bone interdigitated with the
Development of an Astm Standard Test Method on X-ray Powder Diffraction Analysis of Hydraulic Cements
X-ray powder diffraction provides a direct analysis of phase abundance of portland cement clinkers and cements. The ASTM C01 (Cement) Committee formed a task group to investigate quantitative X-ray powder diffraction analysis that resulted in the ASTM C 1365 standard test for X-r
Pore Structure Changes of Blended Cement Pastes Containing Fly Ash, Rice Husk Ash, and Palm Oil Fuel Ash Caused by Carbonation
In this paper, the effects of carbonation on pore structure of blended pozzolan cement pastes were investigated. Ordinary Portland cement OPC was partially replaced with ground palm oil fuel ash POA , ground rice husk ash RHA and classified fine fly ash FA . The strength, total p
Systematic diagenetic changes in the grain-scale morphology and permeability of a quartz-cemented quartz arenite
The material properties of sedimentary rocks are controlled by a range of parameters, including grain size, sorting, and modification of the original sediment through the diagenetic processes of compaction and cementation. To isolate the effects of diagenesis, and explore how the
Effect of surface conditioning with airborne-particle abrasion on the tensile strength of polymeric CAD/CAM crowns luted with self-adhesive and conventional resin cements.
STATEMENT OF PROBLEM Adhesively bonded, industrially polymerized resins have been suggested as definitive restorative materials. It is claimed that such resins present similar mechanical properties to glass ceramic. PURPOSE The purpose of this study was to assess the tensile stre
Spectra of Cemented, Hematite-rich Material and Tes Spectra of Sinus
Introduction. Lane et al. [1] and Christensen et al. [2] conclude that 1996 Global Surveyor Thermal Emission Spectrometer (TES, ~1700–200 cm) spectra of regions in Sinus Meridiani are consistent with hematite. The observed band strengths are inconsistent with unconsolidated, nano
