Shear Strength Behavior for Unsoaked and Soaked Multistage Triaxial Drained Test

Effects of Ballast Degradation on Shear Strength Behavior from Large-scale Triaxial Tests

Ballast, typically comprising large sized aggregate particles with uniform gradation, is an essential layer in the railroad track substructure. Functions of ballast include facilitating load distribution and drainage, maintaining track geometry and track stability, and providing track resilience and noise absorption. Throughout its service life, ballast goes through changes in gradation and par...

Evaluation of undrained response from drained triaxial shear tests: DEM simulations and Experiments

FT-Raman Spectra of Unsoaked and NaOH-Soaked Wheat Kernels, Bran, and Ferulic Acid

Cereal Chem. 80(2):188–192 The sodium hydroxide (NaOH) test for determining wheat color class depends on the observation that on soaking in NaOH, red wheat turns a darker red and white wheat turns straw yellow. To understand the mechanism of this test, Raman spectra of wheat bran, wheat starch, ferulic acid, and whole kernels of wheat, before and after NaOH soak, were studied. The major observa...

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

undrained triaxial shear behavior of grouted carbonate sands

the effects of cementation and the physical properties of grains on the shear behavior of grouted sands are investigated in this paper. the consolidated-undrained triaxial shear behavior of three grouted carbonate sands with different physical properties, including particle size distribution, particle shape and void ratio, was studied. two sands were obtained from the north shores of the persia...
