PART II - CHEMICAL STABILIZATION OF PUERTO RICO LOW-GRADE SOILS

THE RESULTS ARE PRESENTED OF A LABORATORY STUDY ON THE STABILIZATION OF A NUMBER OF PUERTO RICO SOILS. PLASTIC SOILS WERE STABILIZED WITH PHOSPHORIC ACID, PDC (A COMMERCIAL ADDITIVE:CASEIN, LIME AND CEMENT) AND BY THE ADDITION OF SAND. PORTLAND CEMENT WAS USED WITH A NON- PLASTIC SAND. DENSITY, PLASTICITY, CBR AND UNCONFINED COMPRESSIVE STRENGTH TESTS WERE USED IN EVALUATING STABILIZATION EFFECTS. WITH PLASTIC SOILS: (1) PHOSPHORIC ACID INCREASED DENSITY AND STRENGTH BUT THERE WERE MIXING DIFFICULTIES, (2) PDC DECREASED PLASTICITY AND INCREASED STRENGTH WHILE PRESENTING NO MIXING PROBLEMS, AND (3) SAND LOWERED PLASTICITY BUT REDUCED STRENGTH. PORTLAND CEMENT WAS EFFECTIVE WITH THE SANDY SOIL. /BPR/
