Characterization of Quarry By-Products as a Partial Replacement of Cement in Cementitious Composites
… quarry by-products: particle size distribution, helium pycnometry, X-Ray diffraction, X-Ray fluorescence, scanning electron microscopy, and a modified ASTM C1897 Method A that utilizes isothermal calorimetry and thermogravimetric analysis. These various methods allowed for the determination of …

Structure Evolution of Silica Aerogel under a Microwave Field
… including absorption surface analysis, Helium pycnometry, Archimedes principle, Fourier transform infrared spectroscopy, X-ray diffraction, and high resolution microscopy. The data obtained revealed that structural differences do exist between microwave- and conventionally processed …

Fabrication of Random Hole Optical Fiber Preforms by Silica Sol-Gel Processing
… The silica gel monoliths are characterized by helium pycnometry and scanning electron microscopy. Various shapes and densities of silica monoliths have been prepared and characterized. Some of these have also drawn into fibers to demonstrate their viability.

The effect of pressure and temperature on the microstructure and mechanical properties of polycrystalline graphites
… were determined from mercury porosimetry and helium pycnometry respectively. The effects of PC and HTHP conditioning on their mechanical properties, were measured by both uniaxial compression fracture tests, and by electrical resistivity measurements. In addition, the triaxial behavioursof the …
