DETERMINATION OF WATER CONTENT OF SOIL SOLIDS BY OVEN DRYING METHOD Aim: To determine the water content of soil solids by Oven Drying method. The water content (w) of a soil sample is equal to the mass of water divided by the mass of solids. Specifications: This test is done as per IS: 2720 (Part II) – 1973. The soil specimen should be
