No special PC software is necessary. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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 by autogenous shrinkage and heat of hydration.
A sample of freshly mixed mortar or concrete is compacted in a circular mold around an instrumented steel ring. Request a Quote Request Services.

So you can easily integrate it into local intranet. So you can easily integrate it into local intranet. The data are visualized online graphical and numerical on the screen.
ASTM 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. Ring for covering the specimen. For more information about Shrinkage Ring – Measuring the Restrained Shrinkageplease call us at 1.
A data-logger supplied with the system ast, strain gage data and store it in the logger as standard ASCII files.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Please download it here!
Strain gage amplifier, thermocouple type K input and digitizing unit, mounted inside the inner ring. Cracking of the test specimen is indicated by a sudden decrease in the steel ring strain. Cracking of the test specimen is indicated by a sudden decrease in the steel ring strain.
Work Item s – proposed revisions of this standard. Network interface and built in WEB-Server, software pre-installed. Network interface and c581 in WEB-Server, software pre-installed.
The logger has a network interface Ethernet. 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.
Data Logger – Order Code: The data of up to 5 rings are digitally transferred to the data-logger. No special PC software is necessary.

Thickness 13 mm, outer diameter mm, height mm, weight The logger has a network interface Ethernet. The procedure can be used to determine the effects of variations in the proportions and material properties of mortar or x1581 on cracking due to both drying shrinkage and deformations caused by autogenous shrinkage and heat of hydration.
Inner diameter mm, height mm. ASTM Shrinkage ring made of steel aetm 4 strain gages. Combining values from the two systems may result in non-conformance with the standard. Bolts, nuts and washers for fixing the rings on the ground plate. The age at cracking and the rate of tensile stress development in asm test specimen are indicators of the materials resistance to cracking under restrained shrinkage cited from the standard.
