Plastic shrinkage in dry mix shotcrete

2009
Plastic shrinkage cracking of dry-mix shotcrete is a common problem encountered within the construction industry. Dry-mix shotcrete is used in a wide variety of applications most commonly, the repair and rehabilitation of deteriorated concrete structures.

An apparatus for measuring the shrinkage characteristics of plastic mortars

Magazine of Concrete Research, 1971
Synopsis An apparatus designed primarily to measure shrinkage forces developed in a restrained specimen of cement paste or mortar is described. On the basis of tests carried out, it is concluded that the apparatus may be used to assess qualitatively the tendency for mortars to form plastic shrinkage cracks.

Modelling the severity of plastic shrinkage cracking in concrete

Cement and Concrete Research, 2013
Abstract 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, 2008
A 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).

Typical plastic shrinkage cracking behaviour of concrete

Magazine of Concrete Research, 2013
Plastic shrinkage cracking (PShC) is one of the earliest forms of cracking in concrete. Concrete structures with large exposed surfaces are especially vulnerable to PShC and the cracks formed are unsightly and can lead to premature durability issues.

Plastic shrinkage cracking of fiber reinforced concrete

2006
The main objective of this study was to investigate the effect of fiber volume (i.e control, 0.5%, 1.0%, and 1.5%) and aspect ratios of 55, 65, and 80 of hooked-end steel fibers on the behaviour of plastic shrinkage cracking during the first few hours after mixing.

Influence of mix and environment on plastic shrinkage cracking

Magazine of Concrete Research, 2003
The influence of mix constituents (including corresponding concrete grade), retarding and air entraining admixtures and PFA additives, and the effect of environmental factors on plastic shrinkage cracking of mortar specimens is reported, supplemented by concurrent evaporation and bleeding tests.
