Plastic shrinkage cracking in 3D printed concrete

Composites Part B: Engineering, 2020
Abstract In concrete, early age pore water evaporation results in volumetric shrinkage that, if restrained, can cause plastic shrinkage cracking (PSC). 3D printed concrete (3DPC) is vulnerable to PSC due to a lack of formwork, minimal bleeding water, low aggregate to binder ratio and high quantities of fines in the mixture.

Influence of Shrinkage-Reducing Admixtures on Development of Plastic Shrinkage Cracks

ACI Materials Journal, 2007
Cracking that forms between concrete placement and concrete setting is generally described as plastic shrinkage cracking. The authors discuss how concave menisci may form on fresh concrete surfaces due to water evaporation. Potential development of plastic shrinkage cracks may occur when concrete surface tensile stress and concrete settlement develop ...

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.

Interaction between settlement and shrinkage cracking in plastic concrete

Construction and Building Materials, 2018
Abstract The plastic period in conventional concrete is dominated by two volume changes namely, plastic settlement and plastic shrinkage, which if restrained can result in cracking. Although both volume changes and the resulting cracking have been well documented cracking during the plastic period remains a problem.

Influence of pozzolan on the plastic shrinkage cracking of concrete

Concrete at its fresh state allows for the occurrence of plastic shrinkage cracks due to the excessive and rapid evaporation rate of water and the inability or lack of bleed water to replace the evaporating water. Plastic shrinkage cracks can occur in concrete slabs, pavements, and flatworks and has been known on occasion to penetrate the whole depth ...
