Determination of organic matter for the classification of soil samples
(1965)Proceedings of the Sixth International Conference on Soil Mechanics and Foundation EngineeringThe organic matter in 53 samples, which according to U.S.C.S. classification should contain organic material, was determined by the wet combustion methods of Schollenberger, and Walkley and Black. It was desired to show whether an estimate of the amount of organic substance in soil could be obtained from the sodium hydroxide test and whether a relationship existed between the sodium hydroxide test and the displacement of the Attenberg ...Conference Paper -
Triaxial and seismic laboratory tests for stress-strain-time studies
(1965)Proceedings of the Sixth International Conference on Soil Mechanics and Foundation EngineeringStress-strain-time studies on granular soils were carried out using a combination of soil mechanical and geophysical methods. A normal triaxial compression apparatus for large samples (diam 25 cm) was fitted with seismic measuring equipment. An explanation is offered for discrepancies in the results obtained for elasticity moduli from quasi-static and dynamic methods, respectively.Conference Paper
