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...

Issue 01/2020

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...

Issue 02/2016 Diatomaceous earth as a functional additive

Improved freeze-thaw resistance, strength and durability of concrete products

Concrete needs to exhibit a high freeze-thaw resistance to ensure long service lives, particularly in the case of concrete products used in road construction. This characteristic is primarily achieved...
