A LABORATORY INVESTIGATION WAS CONDUCTED TO FIND RELATIONSHIPS BETWEEN STRENGTH AND DENSITY FOR CEMENT- TREATED SOIL MIXTURES COMPACTED AT DIFFERENT MOISTURE CONTENTS. A DUNE SAND AND THREE CLAYS WERE USED TO PREPARE SAND-CLAY MIXTURES HAVING DIFFERENT AMOUNTS AND DOMINANT KINDS OF CLAY MINERALS. TEST SPECIMENS OF EACH CEMENT- TREATED MIXTURE WERE MOLDED TO NEAR STANDARD AND MODIFIED PROCTOR DENSITY, MOIST CURED 7 OR 28 DAYS, AND THEN IMMERSED IN WATER FOR 24 HOURS BEFORE BEING TESTED FOR UNCONFINED COMPRESSIVE STRENGTH. TEST RESULTS SHOW THAT THE OPTIMUM MOISTURE CONTENT FOR MAXIMUM DENSITY AND THE OPTIMUM MOISTURE CONTENT FOR MAXIMUM UNCONFINED COMPRESSIVE STRENGTH OF CEMENT-TREATED SAND-CLAY MIXTURES ARE NOT NECESSARILY THE SAME. THE MOISTURE CONTENTS FOR MAXIMUM STRENGTHS ARE TO THE DRY SIDE FOR SAND-CLAY MIXTURES DOMINANT IN CLAY. AS CLAY CONTENT INCREASES, THE OPTIMUM MOISTURE CONTENT FOR BOTH MAXIMUM DENSITY AND MAXIMUM STRENGTH VALUES DECREASES. ALSO PRESENTED ARE THE INCREASE IN DENSITY AND IN STRENGTH FOR THE DIFFERENT SOILS WHEN THE COMPACTION EFFORT IS INCREASED FROM STANDARD TO MODIFIED. THE INFLUENCE OF DIFFERENT KINDS OF CLAY MINERALS ON THE RELATIONSHIPS STUDIED DOES NOT APPEAR TO BE SIGNIFICANT. /AUTHOR/
