The results concluded that the Havelian Landslide failure was likely triggered by the reduction in shear resistance of the matrix material (passing #4 sieve fraction
), as a result of increasing moisture content due to rain water infiltration.
The analyzer shakes and taps samples with the same stroke and frequency of manual shakers and then automatically classifies and weighs each sieve fraction
, calculates and stores weight values, and reports the data to a computer.
The analyzer automatically classifies and weighs each sieve fraction
, calculates and stores weight values, and reports the data to a PC in a format compatible with most Windows-based QC/SPC software.
The following interpretation is primarily of a speculative nature and would have to be backed up by a suitable choice of experimental carbon blacks and exact basic conditions (e.g., conveying of only one specific sieve fraction
, as well as exactly set amounts of bead assistants).
These are configured by the user as sieve equivalents, which can be defined to be equivalent to historical sieve fraction
sizes, if desired.
The individual sieve fractions
were weighed and subsequent weights were recorded.
All the sieve fractions
were then analyzed chemically (for Si Mg Al) on atomic absorption spectrometer model Z- 8000 Hitachi Japan.
Eleven sieve fractions
were determined at 0.5[Theta] intervals, where [Theta] is the negative log to base 2 of the sieve aperture size in millimetres (Krumbein 1934).
The sieve fractions
of UWMS were analyzed' for percent MB clay for both Grede and Neenah sands.
