shrinkage cracking

shrinkage cracking

Cracking of a concrete structure or member owing to failure in tension caused by external or internal restraints as reduction in moisture content develops, or as carbonation in the concrete occurs, or both.

It's dry - the use of plasterboard dry-lining inside the house instead of wet plaster can minimise drying-out shrinkage cracking and it's quick to decorate.
Daly (1999) reported that restrained shrinkage-induced cracks cause 12% and 10-14% of deteriorations in the bridges in France and in Germany, respectively; in UK and Norway the shrinkage cracking is one of the major causes of such defects.
The objectives of this study were 1) to analyze the direct relationship between shrinkage cracking and transverse tensile characteristics in moisture saturated wood, and 2) to compare measured tensile strength with published data on the maximum shrinkage, compression yield, and relaxed compression yield stresses from the same wood species.
Remember that shrinkage cracking is cosmetic, and that the additional cost for reducing shrinkage cracking is really only justified where appearances are critical.
With the exception of the test site in Washington State, shrinkage cracking plagued repairs at all other sites.
Its strength develops in a progressive manner as the concrete ages, resulting in a highly durable material that also exhibits a good resistance to shrinkage cracking.
