Measuring the Restrained Shrinkage According to
Schleibinger Shrinkage Ring for determination of age at cracking and induced tensile stress characteristics of mortar and concrete under restrained shrinkage according to ASTM C1581.
Data logger is necessary to collect the measured data (order no. S0003). Up to 5 Schleibinger Shrinkage rings can be connected to the data logger.
inner steel ring Ø330 x 13 x 150 mm, tolerances according to ASME B 46.1.
outer ring: stainles steell Ø405 mm
base plate: made of Polypropylene
ASTM Shrinkage ring with strain gauges and measuring amplifier
Screws and washers for attaching the rings to the mounting base plate
