ANSWER-

    Saturated surface dry:

    It is defined as the condition in aggregates in which the surface is dry but the inner particle void are saturated with water, this condition make no surface adsorption through aggregates.

    Free moisture:

    It is defined as the moisture not retained or absorbed by the aggregates, also the moisture which can be removed by air drying.

      TOTAL MOISTURE CONTENT-

      Sample A = 620-592.6 = 27.4g

      Sample B = 622.6-591.7 = 30.9g

      Sample C= 620.9-593.5 = 27.4g

      AVERAGE

      FOR WET SAMPLES A, B, & C = 621.1667

      FOR DRY SAMPLES A, B, & C = 592.6

      STANDARD DEVIATION

      FOR WET SAMPLES A, B, & C = 1.320353

      FOR DRY SAMPLES A, B, & C = 0.9

      FREE MOISTURE CONTENT

      SAMPLE A = 620-5926 * 100-4419355

      SAMPLE B = 622.6-591.7 * 100 = 4.963058 622.6

      SAMPLE C = 620.9-593.5 1004.4192949 620.9
