Ls100q

The physical and mechanical characteristics of the glass waste used were obtained by different analytical techniques: laser granulometry (COULTER LS 100 Q, Oberkochen, Germany), X-ray diffraction observation (OLYMPUS, Hamburg, Germany) and scanning electron microscope (ZEISS EVO 10 SEM, Oberkochen, Germany). It should be noted that all the ground glass powder cited comes from the same batch of waste.
The glass waste was turned into ground glass powder with different granulometries in order to compare the effect of size on the physical and mechanical properties of the cementitious material. The classification of the glass was carried out in different phases.

The average size and size distribution of the produced microspheres were determined by analyzing a dispersion of lyophilized particles in 0.5% w/v of aqueous PVA by laser light scattering (employing a Coulter LS 100Q, Madison, WI, USA). The average size of MS was expressed as the mean volume diameter ± the standard deviation of the values collected from at least three independent lots.

To examine the recent changes in the spatial patterns of sediment in and around the outer Yangtze subaqueous delta, we obtained surficial sediment samples (upper 30 cm) using a box sampler in April 2008 and July 2011. In the laboratory, the grain-size distributions of the sediment were determined using a laser particle size analyser (LS-100Q, Beckman Coulter Corporation, USA), which subdivides each sample into 117 size fractions between 0.0002 mm and 2 mm. Prior to grain-size analysis, the organic matter and carbonate were removed from the sediment samples using H₂O₂ and HCl. The aggregates were then dispersed by the addition of (NaPO₃)₆ and subsequent ultrasonic treatment. The sand–mud border in the East China Sea was determined by interpolation. The sand percentage was >50% on the seaward side of the sand–mud border, and the mud (silt and clay) percentage was >50% on the landward side of this border.
