Title: CONSOLIDATION CHARACTERISTICS OF STABILIZED CLAYEY SOILS
Accession Number: 00237197
Record Type: Component
Abstract: THREE TYPICAL CLAYEY SOILS WERE STABILIZED WITH PORTLAND CEMENT, LIME AND SODIUM HYDROXIDE, AND THEIR CONSOLIDATION CHARACTERISTICS WERE COMPARED WITH THOSE OF THE NATURAL SOILS. THE SOILS, WHOSE CLAY CONTENT VARIED, CONTAINED KAOLINITE, ILLITE OR MONTMORILLONITE AS THE CLAY MINERAL. THEY WERE COMPACTED TO STANDARD PROCTOR DENSITY AT OPTIMUM MOISTURE CONTENT, THEN CURED FOR 28 DAYS IN NEAR 100 PERCENT RELATIVE HUMIDITY AT ROOM TEMPERATURE AND SUBSEQUENTLY TESTED IN A DOUBLE DRAINAGE FIXED TYPE CONSOLIDOMETER UP TO 8 KG/CM SQUARED LOADS. SATURATED AND UNSATURATED TESTS WERE RUN. IN ALL CASES, THE BENEFICIAL EFFECT OF STABILIZATION WAS OBSERVED BY THE FLATTENING OF THE E-LOG P CURVES. CONSOLIDATION SEEMED TO HAVE A STABILIZING CHARACTER, WHOSE INFLUENCE APPROACHED THAT OF THE STABILIZING AGENTS AT HIGH COMPRESSIVE LOADS ONLY. THE APPLICATION OF THE CONSOLIDATION LOAD CAUSED A REARRANGEMENT OF THE PARTICLES AND THE GEOMETRY OF THE SOIL STRUCTURE APPARENTLY CHANGED. THE CHANGE WAS LARGE FOR THE NATURAL SOIL AND SMALL FOR ITS STABILIZED COUNTERPART. THE MAJOR CONTRIBUTION OF STABILIZING AGENTS WAS TO BRING ABOUT AN INITIAL BONDING WHICH PREVENTED THE DETRIMENTAL EFFECT OF THICKNESS CHANGE IN THE SOIL-PAVEMENT COMPONENTS.
