Freeze and Thaw Performance of Internally Cured Concrete ...

2020-12-11  The durability of concrete structures is generally improved through the use of internal curing (IC). IC concrete mixtures can increase the sustainability of concrete by reducing the drying and autogenous shrinkage cracking and improving the degree of hydration. Studies have been performed to assess the freeze-thaw performance of concrete mixtures.

Improvement in freeze-thaw durability of recycled ...

2021-1-25  Currently, there are few effective methods for improving the freeze–thaw durability of recycled aggregate (RA) permeable concrete without reducing the strength or permeability. Thus, this study aims to improve the freeze–thaw durability of recycled aggregate permeable concrete without the degradation of strength and permeability.

2019-4-1  However, when the cement content is 5% or higher, the CSM samples exhibited better freeze–thaw durability. For instance, the residual strength ratio of sample C7P0.25 decreased to only 0.80 at the 30th freeze–thaw cycle. The above results show that the cement content effectively improves the freeze–thaw durability of CSM.

Freezing and Thawing Behavior of Internally Cured Concrete

2015-5-21  It is shown that when concrete is designed with a low water/cement ratio (w/c) (approximately 0.42 or lower) and a volume of internal curing water is added to match the chemical shrinkage volume, the internally cured concrete mixtures showed a very low potential for freeze–thaw damage (comparable to that of conventional concrete).

Higher strength, lower water to cement ratio (w/c) concrete has been advocated over the last two decades due to its increased strength and reduced permeability. The lower w/c of these concretes makes them susceptible to autogenous shrinkage. This autogenous shrinkage can be significant and can be a contributing factor to early age cracking. Internal curing was investigated as a potential ...
