Summary

THE EFFECT OF WATER CONTENT ON THE APPARENT THERMAL DIFFUSIVITY OF A SOIL HAS BEEN INVESTIGATED IN RELATION TO TIME AND POSITION IN THE DIRECTION OF HEAT FLUX. THE SAMPLE USED FOR EXPERIMENTS WAS A SAND WHOSE MEAN GRAIN SIZE WAS 208 MICROMETERS AND MEAN DRY BULK DENSITY ABOUT 1,360 KG/M3. THE MEASUREMENTS WERE CONDUCTED OVER A RANGE OF WATER CONTENT FROM 0 TO 93.9% AND FROM 293 TO 313 K (20 TO 40 DEG C). THE RESULT SHOWS THAT THE THERMAL DIFFUSIVITY IN THE CASE OF 9.6%, OF WATER CHANGES WITH TIME.
