Plastic shrinkage of steel fibre reinforced concrete

Materials and Structures, 1990
The paper presents the results of an experimental investigation on the plastic shrinkage of steel fibre reinforced concrete (SFRC). Tests were carried out on mixes with cement content ranging between 370 and 468 kg m−3. Four types of steel fibres were used: melt extract, hooked, crimped and Harex. The volume of, fibres ranged between 0 and 4.47% of the

Plastic Shrinkage Cracking and Evaporation Formulae

ACI Materials Journal, 1998
Freshly 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.

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 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.

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.

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.

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.
