Detailed Procedure. —For shaped test pieces details of the procedure are given under the headings. “Preparation of Test Piece.”“Determination of Dry Weight,”“The Absorption Apparatus,”“Preparation of Standard Vaseline,”“Saturation Procedure,”“Calculation,” and “True Density.” A Pycnometer Method. —A new and accurate method, which is applicable equally to shaped test pieces or to granular material, is described. Among other advantages it gives the operator control over the max. size opening which he desires to class as part of the pore space. It also can be made to indicate directly the necessary soaking period.
