Cyclic Triaxial Behavior of Monterey No. 0 and No. 0/30 Sands

摘要

The purpose of this study was to compare the cyclic triaxial behavior of Monterey No. 0 sand to a sand currently being produced by Lone Star Industries. The sand is known as Monterey No. 0/30 sand and has physical properties very similar to Monterey No. 0 sand. A small amount of the Monterey No. 0 sand remaining from the 1976 cooperative testing program was obtained from one of the eight participating laboratories. The behavior of this sand was compared to that of the Monterey No. 0/30 sand by using the stress-controlled cyclic triaxial strength test. The results of the study show that differences in the cyclic shear strength, grain size distribution, minimum density, and chemical composition lead to questions regarding the validity of using Monterey No. 0/30 sand as a replacement for Monterey No. 0 sand.
