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.

Network interface and c1518 in WEB-Server, software pre-installed.

Two temperature channels and a mixed temperature-humidity channel are available. Powered by CMSimple Template: Cracking of the test specimen is indicated by a sudden decrease in the steel ring strain.

Serial digital SMB bus interface to the data logger S So you can easily integrate it into local intranet. Optional a synchronous registration of temperature and humidity of a balance c1518 possible.

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 aatm and heat of hydration.

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.

The data of up x1581 5 rings are digitally transferred to the data-logger. No special PC software is necessary. Outer ring made of stainless steel. With a standard web-browser software you can readout the data and visualize it. Other sizes on request.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. October 18, Combining values from the two systems may result in non-conformance with the standard.

Warning —Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. So you can easily integrate it into local intranet.

The logger has a network interface Ethernet. For more information about Shrinkage Ring – Measuring the Restrained Shrinkage aetm, please call us at 1.

ASTM C This test method covers the laboratory determination ashm the age at cracking and induced tensile stress characteristics of mortar or concrete specimens under restrained shrinkage. 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. Base made of PP. A sample of freshly mixed mortar or concrete x1581 compacted in a circular mold around an instrumented steel ring.

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.

Bolts, nuts and washers for fixing the rings on the ground plate. Data Logger – Order Code: 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.

With standard web-browser software you can readout the data and visualize it. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not zstm as part of the standard.
