Base made of PP. The age at cracking and the rate of tensile stress development in the test specimen are indicators of the materials resistance to cracking under restrained shrinkage cited from the standard.

Schleibinger Testing Systems – ASTM-Shrinkage Ring

The logger has a network interface Ethernet. A sample of freshly mixed mortar or concrete is compacted in a circular mold around an instrumented steel ring.

Ring for covering the specimen. These variations can include, but are not limited to, aggregate source, aggregate gradation, cement type, cement content, water content, supplementary cementing materials, or chemical admixtures.

With standard web-browser software you can readout the data and visualize it. So you can easily integrate it into local intranet. The data of up to 5 rings are digitally transferred to the data-logger.


The logger has a network interface Ethernet. Cracking of the test specimen is indicated by a sudden decrease in the steel ring strain. The data are visualized online graphical and numerical on the screen. A data-logger supplied with the system records strain gage data and store it in the logger as standard ASCII files.

Wstm C This test method covers the laboratory determination of the age at cracking and induced tensile stress characteristics of mortar or concrete specimens under restrained shrinkage.

Measurement Principle A sample of freshly mixed mortar or concrete is compacted in a circular mold around an instrumented steel ring.

Inner diameter mm, height mm. Serial c5181 SMB bus interface to the data logger S Data logger with an interface for up to 5 rings S Data Logger – Order Code: October 18, Outer ring made of stainless steel.

Powered by CMSimple Template: Thickness 13 mm, outer diameter mm, height mm, weight The procedure can be used to determine the effects of variations in the proportions and material properties of mortar or concrete on cracking due to both drying shrinkage and deformations caused cc1581 autogenous shrinkage and heat of hydration.


The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

Network interface and built in WEB-Server, software pre-installed. So you can easily integrate it into local intranet.

Shrinkage Ring – Measuring the Restrained Shrinkage

The compressive strain developed in the steel ring caused by shrinkage of the mortar or concrete specimen is measured with 4 strain gages from the time of casting. Historical Version s – view previous versions of standard.
