Freeze Thaw Durability - an overview ScienceDirect Topics

There are a number of tests available to assess the freeze–thaw durability of concrete. These all involve subjecting a concrete specimen to freeze–thaw cycles in some specific way, and then determining the damage to the concrete by measuring such parameters as weight loss, loss in strength, loss in dynamic modulus, or length change. In North America, the most common test is that described ...

Dec 12, 2019  Concrete durability in climates where freezing and thawing occurs is a continuing problem. It is particularly acute for highway and bridge structures, where de-icing salts are used to combat the effects of frost, snow and ice. These salts can cause damage to concrete and accelerate corrosion of reinforcements. This book presents the latest international research on this area, with ...

Freeze-Thaw Durability of Air-Entrained Concrete

Mar 21, 2013  One of the most damaging actions affecting concrete is the abrupt temperature change (freeze-thaw cycles). The types of deterioration of concrete structures by cyclic freeze-thaw can be largely classified into surface scaling (characterized by the weight loss) and internal crack growth (characterized by the loss of dynamic modulus of elasticity). The present study explored the durability

Jun 12, 2018  The damages caused by cyclic freeze-thaw (F-T) action can be divided into two factors. The first factor is an increase in internal cracking, which causes the loss in relative dynamic modulus (RDM) of the concrete, and the second factor is surface scaling, which leads to weight loss of the concrete.

Obviously, a well-cured concrete with an air-entrainment agent should be the best solution against the freeze-thaw cycle and scaling behaviour of concrete. In the practical case of in situ concrete, with a bad curing process, shrinkage cracking will appear and the microstructure will be more porous, with both being detrimental to the freezing ...
