Title: EFFECTS OF REPEATED LOADS ON ELASTIC MICACEOUS SOILS STABILIZED WITH PORTLAND CEMENT
Accession Number: 00230523
Record Type: Component
Abstract: THE RESULTS OF A LABORATORY STUDY OF THE EFFECTS OF REPEATED LOAD TRIAXIAL TESTS ON THE STRESS-DEFORMATION CHARACTERISTICS AND RESILIENT PROPERTIES OF TWO ELASTIC MICACEOUS SOILS STABILIZED WITH PORTLAND CEMENT ARE DISCUSSED. THE ULTIMATE STRENGTH AND STRESS-DEFORMATION CURVES FOR BOTH UNTREATED AND CEMENT-TREATED SOILS ARE REPORTED FOR BOTH CONVENTIONAL AND REPEATED TRIAXIAL LOADINGS. THE ADDITION OF PROPER AMOUNTS OF PORTLAND CEMENT TO THESE SOILS GREATLY INCREASES THE STRENGTH AND STIFFNESS AND REDUCES THE RESILIENCE CONSIDERABLY. HOWEVER, THE STRENGTH AND STIFFNESS OF CEMENT-TREATED SOILS UNDER THE ACTION OF REPEATED LOADS ARE NOT PROPERLY REPRESENTED BY THE RESULTS OF A CONVENTIONAL /GRADUALLY APPLIED LOAD/ TRIAXIAL TEST. BOTH THE ULTIMATE STRENGTH AND STIFFNESS ARE LESS WHEN OBTAINED IN A REPEATED LOAD TEST. THE ELASTIC REBOUND OR RESILIENCY FOR BOTH UNTREATED AND CEMENT-TREATED SOILS APPEARS TO BE DIRECTLY AND PERHAPS UNIQUELY RELATED TO THE RATIO OF THE APPLIED REPEATED DEVIATOR STRESS TO THE COMPRESSIVE STRENGTH AS DETERMINED IN A CONVENTIONAL TRIAXIAL TEST. /AUTHOR/
