ASTM C341/C341M − 13 Standard Practice for Preparation and Conditioning of Cast Drilled or Sawed Specimens of Hydraulic Cement Mortar and Concrete Used for Length Change Measurements

Scope of ASTM C341/C341M − 13 Standard Practice for Preparation and Conditioning of Cast Drilled or Sawed Specimens of Hydraulic Cement Mortar and Concrete Used for Length Change Measurements

1.1 This practice covers the procedures for the preparation and conditioning of cast, drilled, or sawed specimens of hydraulic-cement mortar and concrete for length change due to causes other than externally applied forces.

It can be readily adapted, if desired, to studies of length change involving alternate schedules or environmental treatment other than the standard procedures prescribed by this practice.

1.2 The values stated in either inch-pound units or SI units shall be regarded separately as standard.

The units stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining in any way. The inch-pound units are shown in brackets.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use
4.1 Measurements of length change permit assessment of the potential for volumetric expansion or contraction of cast, drilled, or sawed specimens of hydraulic-cement mortar, and concrete due to various causes other than externally applied forces and temperature changes. This practice is particularly useful for comparative evaluation of this potential in different mortar or concrete specimens.
