1. 1 This method describes a procedure to determine the change in length in cement mortars and concrete, due to causes other than those produced by the application of external forces or changes in temperature. The method is intended to be used as a basis of acceptance, but may be adapted to perform volume change studies involving programming or environmental treatments other than those prescribed here. 1.2 The term "change in length" is defined as an increase or decrease in a linear dimension of a specimen due to causes other than those produced by the application of external forces or changes in temperature.
