This shrinkage apparatus is used to measure length variations in mortar specimens after autoclave expansion tests or when checking shrinkage effect. The equipment is designed for accurate measurements in laboratory environments and is well suited for testing where stability and comparable results are important.

The top beam is adjustable so the equipment can be adapted to the length of the specimen, making it flexible for different test pieces. It is used in testing according to EN 12617-4, EN 1367-4 and EN 12808-4 and is available under item numbers E077-KIT and E078-KIT.
