DETERMINATION OF THE CEMENT OR LIME CONTENT OF STABILIZED FERRUGINOUS SOILS

USUALLY CALCIUM IS EXTRACTED FROM SOIL WITH HYDROCHLORIC ACID AND, AFTER REMOVAL OF THE SESQUIOXIDES, THE CALCIUM IS DETERMINED BY DIRECT TITRATION WITH ETHYLENE-DIAMINETETRA-ACETIC ACID SOLUTION. IN THE PRESENT INVESTIGATION IT IS SHOWN THAT COPRECIPITATION EFFECTS MUST BE ALLOWED FOR IN CASES WHERE A SOIL CONTAINING NO CALCIUM AND A HIGH PROPORTION OF IRON AND ALUMINUM HAS BEEN STABILIZED WITH A LOW PROPORTION OF LIME OR CEMENT. SUCH CONDITIONS CAN ARISE WITH TROPICAL SOILS RICH IN IRON AND ALUMINUM.
