APPARATUS FOR DETERMINING S.S.D STATE OF FINE AGGREGATE

In an attempt to employ the principles of thermodynamics to measure moisture changes in the testing medium, a testing apparatus was constructed (following initial experimentation) which incorporated a method of blending the moist material while the drying process is proceeding, thus causing the various size of aggregate to achieve the saturated surface dry conditions at the same point in time. Details of the original apparatus and refinements to it are outlined. An example of the general curve developed by the testing apparatus is shown, the interpretation of the regions of the saturated surface dry general curve is discussed, and a theoretical explanation of the general curve is described. New concepts are listed which were developed from improvement of the specific gravity testing.
