THE PHYSICAL PROPERTIES OF SOILS 



THIRD EXERCISE 



I. DETERMINATION OF VOLUME WEIGHT 

 AND PORE SPACE OF STOCK SOILS 



The volume weight of a soil is the weight of a given 

 vokime. The weight of the soil in grams divided by 

 the volume in cubic centimeters is the density or the 

 apparent specific gravity. 



APPARATUS FOR THE DETERMINATION OF VOLUME WEIGHT AND 



PORE SPACE 



METHOD OF DETERMINATION 



Secure a brass cylinder (T), weigh empty, and fill 

 with soil No. I, compacting it on the iron compactor 

 by dropping the weight four times from the 6-inch 

 mark after each measure of soil. Weigh the tube when 

 level full and empty the soil back into the bin. Secure 

 the weight of the cylinder full of each of the soils in this
