CRD-C231-63 Method of Test for Volume Changes in Neat Cement Bars
This test method covers procedures for determining the volume changes in neat cement bars produced by prolonged saturation followed by prolonged drying, and alternate saturation and drying. The procedures simulate some of the conditions in nature that cause stress and consequent volume change. Volume change will be measured and expressed as an increase or decrease in the original axial gage length of the test specimen.
