Plastic Shrinkage Cracking of Concrete
Australian Journal of Structural Engineering, 2010Plastic shrinkage cracking, which occurs during the first several hours after the casting of concrete, is of considerable economic significance in the concrete construction industry. In this paper, the mechanism of plastic shrinkage cracking and its related phenomena of evaporation and bleeding are first reviewed.

Plastic shrinkage cracking in concrete is due to evaporation, which is aggravated by harsh environmental conditions. By controlling the conditions in a laboratory to cause high evaporation rates, plastic shrinkage cracks can be induced and then tested ...

Magazine of Concrete Research, 2022
Plastic shrinkage cracking propagating at early ages inevitably impairs the performance of concrete structures. To mitigate this, using a recently developed shrinkage-reducing polycarboxylate superplasticiser (SR-PCA) with outstanding shrinkage-reducing and water-reducing effectiveness can be a promising approach.

The severity of plastic shrinkage cracking in concrete: a new model
Magazine of Concrete Research, 2021Plastic shrinkage cracking in concrete is mainly a physical process, in which chemical reactions between cement and water do not play a decisive role. It is commonly believed that rapid and excessive moisture loss due to evaporation is the primary cause of the phenomenon.

Modelling the severity of plastic shrinkage cracking in concrete
Cement and Concrete Research, 2013Abstract Plastic shrinkage cracking (PShC) is one of the earliest forms of cracking in concrete as it occurs within the first few hours after the concrete has been cast. Concrete elements with large exposed surfaces are especially vulnerable to PShC.

Plastic shrinkage cracking in cementitious repairs and overlays
Materials and Structures, 2008A study was undertaken to investigate the influence of mixture proportions on plastic shrinkage cracking in cementitious repairs and overlays. The following variables were studied: water-cement ratio (w/c), sand-cement ratio (s/c) aggregate-cement ratio (a/c), fly-ash content, and the presence of a shrinkage reducing admixture (SRA).

Plastic Shrinkage Cracking and Evaporation Formulae
ACI Materials Journal, 1998Freshly placed concrete exposed to hot, windy conditions is often prone to plastic shrinkage cracking, though other conditions can also promote this phenomenon. This type of cracking is normally noticed on slabs, pavements, beams, and generally other flat concrete surfaces.

Influence of Crumb Rubber on the Drying Shrinkage and Plastic Shrinkage Cracking of AASM
Materials Science Forum, 2013The alkali-activated slag mortar (AASM) has disadvantages of high shrinkage and therefore low crack resistance. In this paper, water quenched raw slag was used to replace sand for making AASM, and effects of crumb rubber on the drying shrinkage and plastic shrinkage cracking of AASM were investigated.
