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.

Plastic shrinkage cracking of fiber reinforced concrete

open access: yes, 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.

Plastic Shrinkage Cracking of Concrete

Australian Journal of Structural Engineering, 2010
Plastic 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.
