RISSampling Disturbance Effects in Normally Consolidated Clays
Publisher: American Society of Civil Engineers
Abstract: The effects of sampling disturbance are investigated by performing single element triaxial tests in which specimens of normally consolidated resedimented Boston blue clay are disturbed according to the “perfect sampling ...
Experimental Study of Wellbore Instability in Clays
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an extensive program of laboratory model wellbore tests that have been performed to study wellbore instability in saturated clays. The tests were conducted on resedimented Boston blue ...
Does Calcium Leaching Increase Ductility of Cementitious Materials? Evidence from Direct Tensile Tests
Publisher: American Society of Civil Engineers
Abstract: There is an ongoing debate in the chemomechanics community over whether calcium leaching leads to an increase in brittleness or ductility of cementitious materials. While other research teams have addressed this question ...
Closure to “Effect of Nonuniform Stresses on Measured DSS Stress‐Strain Behavior” by Don J. DeGroot, John T. Germaine, and Charles C. Ladd
Publisher: American Society of Civil Engineers
Factors Affecting the Initial Stiffness of Cohesive Soils
Publisher: American Society of Civil Engineers
Abstract: The paper presents the results of an extensive laboratory program conducted to establish the factors affecting the initial stiffness (Young’s modulus) of cohesive soils in undrained triaxial compression. The testing program, ...
Effects of Soils on Laser Induced Fluorescence of BTX Contaminated Pore Waters
Publisher: American Society of Civil Engineers
Abstract: A laboratory testing program was conducted to identify and interpret the fundamental factors affecting the performance of a new microchip-laser based fluorescence sensor in soil and ground water. Investigations were performed ...
Laboratory Simulation of Field Sampling: Comparison With Ideal Sampling and Field Data
Publisher: American Society of Civil Engineers
Abstract: Tube sampling disturbance effects are investigated in this paper based on the results of constant rate of strain consolidation tests and unconsolidated undrained triaxial compression tests conducted on resedimented Boston ...
Small-Strain Nonlinearity of Normally Consolidated Clay
Publisher: American Society of Civil Engineers
Abstract: This paper addresses the small-strain undrained shear behavior of clays based on an extensive testing program conducted on normally consolidated resedimented Boston blue clay (RBBC). The uniformity and reproducibility in ...
Triaxial Testing of Frozen Sand: Equipment and Example Results
Publisher: American Society of Civil Engineers
Abstract: This paper describes a high-pressure, low-temperature triaxial testing system that has been specifically designed and built at the Massachusettes Institute of Technology in order to study the physical mechanisms controlling ...
Effect of Nonuniform Stresses on Measured DSS Stress‐Strain Behavior
Publisher: American Society of Civil Engineers
Abstract: This paper presents results of a laboratory investigation of the influence of the nonuniform stresses imposed by the Geonor direct simple‐shear (DSS) apparatus on measured stress‐strain behavior. The investigation concentrated ...
