Abstract:

NINE CLAY SOIL SAMPLES REPRESENTATIVE OF LOCAL PROBLEM SOILS WERE TESTED FOR PHYSICAL, PHYSICOCHEMICAL, AND MINERALOGICAL PROPERTIES, AND THE RELATIONSHIPS AND CORRELATIONS AMONG THEM WERE DETERMINED BY ANALYSIS OF THE RESULTS. CONSOLIDATION TESTS ON COMPACTED SAMPLES WERE STUDIED TO OBTAIN CONSOLIDATION AND EXPANSION DATA FOR CORRELATION WITH CLAY MINERALOGY, PH OF THE SOIL-WATER SYSTEM, ORGANIC CARBON CONTENT. AND CATION EXCHANGE CAPACITY. THE MINERALOGY OF THE SOILS WAS DETERMINED BY X-RAY DIFFRACTION. THE CLAY MINERALOGY OF SOILS OF GLACIAL ORIGIN CONSISTS OF KAOLINITE, ILLITE, AND ILLITE-MONTMORILLONITE IN VARYING PROPORTIONS, WHEREAS THOSE OF DOLOMITIC ORIGIN CONSIST OF MONTMORILLONITE CALCIUM, MAGNESIUM, AND LESSER AMOUNTS OF SODIUM, POTASSIUM, AND MANGANESE TOGETHER WITH TRACES OF IRON AND ALUMINUM. THEY WERE ALL CLASSED AS SWELLING CLAYS, AND THE COMPRESSION INDEX WAS MORE SENSITIVE THAN THE EXPANSION INDEX TO DIFFERENCES IN CLAY MINERALOGY. A LINEAR RELATIONSHIP BETWEEN CARBONATE CONTENT AND CATION EXCHANGE CAPACITY WAS OBTAINED, AND TENTATIVE EXPRESSIONS WERE DERIVED FOR ESTIMATIONS OF CATION EXCHANGE CAPACITY FROM VALUES OF THE PLASTIC OR SHRINKAGE LIMITS FOR SOILS OF SIMILAR CLAY MINERALOGY. EFFECTIVITY OF LIME IN INCREASING THE PLASTIC LIMIT AND DECREASING THE PLASTICITY INDEX OF THE SOIL WAS NOTED, AND SOIL MINERALOGY-CARBONATES AND PROPORTIONS WERE FOUND TO CORRELATE WITH SOIL PROPERTIES. /AUTHOR/
