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

Schleibinger Testing Systems

Network interface and built in WEB-Server, software pre-installed. Combining values from the two systems may result in non-conformance with the 1c581.

The data are visualized online graphical and numerical on the screen.

Two temperature channels and a mixed temperature-humidity channel are available. 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.

Schleibinger Testing Systems – ASTM-Shrinkage Ring

The procedure can be qstm 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.

Steel ring strain vs. Link to Active This link will always route to the current Active version of the standard. Ring for covering the specimen. So you can easily integrate it into local intranet. 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.

The values stated in each system may not be exact equivalents; therefore, each system shall awtm used independently of the other. October 18, The specimen is cracking after 6. 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. Work Item s – proposed revisions of this standard. Inner diameter mm, height mm. Data Logger – Order Code: Powered by CMSimple Template: A sample of freshly mixed mortar or concrete is compacted in a circular mold around an instrumented steel ring.

Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. ASTM C This test method covers the laboratory determination of the age at cracking and induced tensile stress characteristics of mortar or concrete specimens c15811 restrained shrinkage.

Cracking of the test specimen is indicated by a sudden decrease in the steel ring strain. The logger has a network interface Ethernet. No special PC software is necessary. 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.

The procedure can aastm 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 logger has a network interface Ethernet.

It is the responsibility of the user of this standard to establish c15581 safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Outer ring made of stainless steel. Actual cracking tendency in service depends cc1581 many variables including type of structure, degree of restraint, rate of property development, construction and curing methods, and environmental conditions. 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.
