Issue 02/2017 New findings and forecast models

Freeze-thaw attack and damage

The freeze-thaw damage pattern of concrete is primarily linked to the water contained in the pore system, which is also referred to as the saturation level. If a certain critical saturation level is...

Determining freeze-thaw resistance of precast products for road pavements under real-life conditions

Since February 2005, the freeze-thaw resistance of concrete pavers had to be determined in the modified slab test in accordance with DIN EN 1338. Some clients favor the CDF method even though there...

Assessment of frost and freeze-thaw damage to concrete pavers (Part 2)

The first part of this article dealt with the different patterns associated with freeze-thaw damage, the impact of cracks occurring in products, and the influence of installation and use on the onset...

Issue 02/2013 Current findings with respect to the XF2 freeze/thaw test method

Freeze/thaw resistance at moderate water saturation levels

Generally accepted, internationally recognized methods (CIF and CDF) exist for testing the freeze/thaw resistance of concrete at high water saturation rates irrespective of the simultaneous action of...

Effect of Calcium Nitrate on the freeze-thaw-resistance of concrete

Abstract Concrete in cold climates is not only exposed to cold weather while concreting but also to freeze-thaw cycles during its lifetime. Thus not only the concrete production needs to be adjusted...
