Comparison of Hand Held Gage and Unconfined Compression Results in Low Strength Cementitious Stabilized Materials
Publication: Geo-Frontiers 2011: Advances in Geotechnical Engineering
Abstract
This paper compares measured shear strength of high moisture content soils stabilized with nine cementitious materials from two penetrometers and one miniature vane shear device to unconfined compression (UC) testing. Three fine grained soils of varying organic content were obtained from New Orleans and Mobile and tested at a water to cementitious ratio of 10; 2,844 readings were taken with each hand held gage on stabilized slurry slabs and 297 UC readings were taken for comparison. Test results indicated the miniature vane shear device was the most accurate but the least precise. Accuracy of the two penetrometers was similar, though precision varied. Shear strength over prediction with the hand held gages became prevalent with increasing organic content. The motivation for the work was to have a rapid method to assess strength development in a family of materials where correlation of hand held gages to UC measured strengths isn't readily available.
