So you can easily integrate it into local intranet. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Two temperature channels and a mixed temperature-humidity channel are available. Thickness 13 mm, outer diameter mm, height mm, weight The logger has a network interface Ethernet.

Combining values from the two systems may result in non-conformance with the standard. Optional a synchronous registration of temperature and humidity of a balance is possible. Steel ring strain vs. Inner diameter mm, height mm. Cracking of the test specimen is indicated by a sudden decrease in the steel ring strain.

Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Ring for covering the specimen. Actual cracking tendency in service depends on many variables including type of structure, degree of restraint, rate of property development, construction and curing methods, and environmental conditions.

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.

The data of up to 5 rings are digitally transferred to the data-logger.

Schleibinger Testing Systems – ASTM-Shrinkage Ring

Bolts, nuts and washers for fixing the rings on the ground plate. A sample of freshly mixed mortar or concrete is compacted in a circular mold around an instrumented steel ring. Aatm 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.

Base made of PP.

Historical Version s – view previous versions of standard. 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. 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.

Are We There Yet?

So you can easily integrate it into local intranet. 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. A data-logger supplied with the system records strain gage data and stores it in the logger as standard Adtm files.

Data Logger – D1581 Code: A data-logger supplied with the system records strain gage data and store it in the logger as standard ASCII files. No special PC software is necessary.

October 18, Strain gage amplifier, thermocouple type K input and digitizing unit, mounted inside the inner ring. Data logger with an interface for up to 5 rings S Cracking of the test specimen is indicated by aastm sudden decrease in the steel ring strain.

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.

With standard web-browser software c1851 can readout c15581 data and visualize it. The data are visualized online graphical and numerical on the screen. 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. 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.

Measurement Principle A sample of freshly mixed mortar or concrete is compacted in a circular mold around an instrumented steel ring. The data are visualized ast, graphical and numerical on the screen. Serial digital SMB bus interface to the data logger S Other sizes on request. The specimen is cracking after 6.
