The state-of-the-art in fluvial hydrodynamics can be examined only
through a careful exploration of the theoretical development and
applied engineering technology. The book is primarily focused,
since most up-to-date research findings in the field are presented,
on the research aspects that involve a comprehensive knowledge of
sediment dynamics in turbulent flows. It begins with the
fundamentals of hydrodynamics and particle motion followed by
turbulence characteristics related to sediment motion. Then, the
sediment dynamics is analysed from a classical perspective by
applying the mean bed shear approach and additionally incorporating
a statistical description for the role of turbulence. The work
finally examines the local scour problems at hydraulic structures
and scale models. It is intended to design as a course textbook in
graduate / research level and a guide for the field engineers as
well, keeping up with modern technological developments. Therefore,
as a simple prerequisite, the background of the readers should have
a basic knowledge in hydraulics in undergraduate level and an
understanding of fundamentals of calculus.
Bulk oxide determinations from a pair of port-land cements provides
the basis for calculation precision and accuracy values for X-ray
fluorescence (XRF) analysis for both the fused glass bead and the
pressed powder sample preparation. This report is the second in a
series on an Inter-laboratory study on chemical analyses of
hydraulic cements by X-ray fluorescence for the purpose of
estimating precision and qualification criteria. Approximately 45
laboratories provided six replicates analyzed in duplicate for two
separate port-land cements containing ca. 5 % limestone, covering
fifteen analytes, CaO, SiO2, Al2O3, Fe2O3, SO3, MgO, Na2O, K2O,
TiO2, P2O5, Mn2O3, SrO, ZnO, Cr2O3, and Cl, with the laboratories
roughly split between the two different sample preparations.
Chemical data using traditional chemical analyses (the Reference
Methods) from the Cement and Concrete Reference Laboratory (CCRL)
proficiency test program were included for comparison to the XRF
results.
Bulk oxide determinations from a pair of portland cements provides
the basis for calculation precision and accuracy values for X-ray
fluorescence (XRF) analysis for both the fused glass bead and the
pressed powder sample preparation. Approximately 45 laboratories
provided six replicates analyzed in duplicate for two separate
portland cements covering eleven analytes, CaO, SiO2, Al2O3, Fe2O3,
SO3, MgO, Na2O, K2O, TiO2, P2O5, and Cl, with the laboratories
roughly split between the two different sample preparations.
