Abstract

This Euopean Standard specifies a method for measuring the relative length changes due to drying (drying shrinkage) of autoclaved aerated concrete manufactured according to EN 771-4 or prEN 12602. The shrinkage characteristics determined according to this method are the following: The conventional reference value of drying shrinkage is the relative length change between two specified moisture contents. The total value of drying shrinkage is the relative length change due to drying from the saturated state until reaching constant length under specified climatic conditions. Other drying shrinkage values may be determined between other parameters to meet other specified national requirements.
