CAUSTIC-THERMAL STABILIZATION OF COHESIVE SOILS /IN GERMAN/

EIGHT COHESIVE SOILS WERE SUBJECTED TO CAUSTIC-THERMAL TREATMENT AT 300 - 800 DEGREES C TO IMPROVE THEIR FROST RESISTANCE AND BEARING CAPACITY. THE PROCESS ELIMINATES THE DANGEROUS AVERAGE-SIZED VOIDS BY CONVERSION OF THE CLAY MINERALS INTO MICACEOUS MINERALS. THE RANGE OF TEMPERATURE FOR SUCCESSFUL STABILIZATION WAS DETERMINED; FOR SLIGHTLY COHESIVE SOILS WHICH TEND TO TURN TO DUST ON HEATING A LOWER TEMPERATURE WAS NEEDED, BUT THIS STILL ENABLED THEM TO BE STABILIZED WITH ONLY HALF THE NORMAL QUANTITY OF PORTLAND CEMENT. IT WAS SHOWN THAT THE COSTS OF SOIL STABILIZATION WITH CEMENT, LIME, OR TAR COULD BE VERY MUCH REDUCED IF CAUSTIC-THERMAL TREATMENT WAS APPLIED. /FG/RRL/
