Title: MOISTURE, DENSITY AND VOLUME CHANGE RELATIONSHIPS OF CLAY SOILS EXPRESSED AS CONSTANTS OF PROPORTIONALITY
Accession Number: 00234394
Record Type: Component
Abstract: THE PROJECT'S PURPOSE WAS TO DEVISE A METHOD FOR ESTABLISHING EMPIRICAL RELATIONSHIPS BETWEEN VOLUME CHANGE AND DENSITY, AND /OR VOLUME CHANGE AND MOISTURE CONTENT. THE SOIL SAMPLES EMPLOYED WERE HOMOIONIC SOILS PREPARED FROM A WARSAW SOIL BY LEACHING PORTIONS OF THE SOIL WITH SUITABLE ELECTROLYTES CONTAINING ONE OF THE CATIONS CHOSEN, NAMELY HYDROGEN, ALUMINUM, FERRIC, AND CALCIUM IONS. THE PREPARED SOILS WERE TESTED IN VARIOUS COMBINATIONS OF DENSITY AND MOISTURE CONTENT CONDITIONS FOR SWELL CHARACTERISTICS. ADDITIONS OF ORGANIC COMPOUNDS WERE INVESTIGATED TO DETERMINE THE INFLUENCE OF NATURAL SOIL ORGANIC MATTER ON SWELL PROPERTIES OF THE PREPARED HOMOIONIC SOILS. LIGNIN WAS USED TO REPRESENT NATURAL SOIL ORGANIC MATTER IN EQUILIBRIUM WITH SOIL MICROBIAL ACTIVITY. HYPOTHESES DERIVED FROM THE INVESTIGATION ARE GIVEN. /AUTHOR/
