Title: SOIL-ORGANIC CATIONIC CHEMICAL-LIGNIN STABILIZATION
Accession Number: 00231426
Record Type: Component
Abstract: RESULTS ARE PRESENTED OF A SERIES OF TESTS PERFORMED ON FOUR IOWA SOILS STABILIZED WITH TWO ORGANIC CATIONIC CHEMICALS IN COMBINATION WITH LIGNIN. THE CHEMICALS USED WERE A QUATERNARY AMMONIUM CHLORIDE AND A FATTY AMINE ACETATE KNOWN COMMERCIALLY AS ARQUAD 2HT AND ARMAC T, RESPECTIVELY. THE LIGNINS USED WERE EITHER COMMERCIALLY AVAILABLE OR IN PILOT PLANT PRODUCTION AND CONTAINED VARYING SUGAR CONTENTS. THE FOUR SOILS RANGED FROM 10 TO 74 PERCENT IN CLAY CONTENT. PRELIMINARY STUDIES OF THE CHEMICALS AND LIGNINS ON ONE OF THE SOILS, A FRIABLE CALCAREOUS LOESS FROM SOUTHWESTERN IOWA, INDICATED THE MOST DESIRABLE MIXING CHRONOLOGY TO BE THE ADDITION OF CHEMICAL SOLUTION FIRST, FOLLOWED BY THE ADDITION OF THE LIGNIN SOLUTION. THE MOST BENEFICIAL LIGNIN FOR EACH ORGANIC CATIONIC CHEMICAL WAS ALSO CHOSEN AND WAS USED THROUGHOUT THE REMAINDER OF TESTING. IN GENERAL, THE USE OF THE SOIL-ORGANIC CATIONIC CHEMICAL-LIGNIN COMBINATION INDICATES INCREASED COMPRESSIVE STRENGTH OF THE SOIL WITH REDUCTION OF MOISTURE ABSORPTION AND EXPANSION DURING COMPLETE IMMERSION IN WATER, THESE BENEFITS BEING SOMEWHAT GREATER WITH THE COMBINATION OF SOIL, CHEMICAL AND LIGNIN THAN WITH THE SOIL AND CHEMICAL ONLY. /AUTHOR/
