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 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.

Effect of a novel shrinkage-reducing polycarboxylate superplasticiser on plastic shrinkage cracking of mortars

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.

A model of plastic shrinkage

Magazine of Concrete Research, 1994
The proposed model of plastic shrinkage is based on the idea that the capillary pressure in a saturated mixture, exposed to drying, depends on the geometry of the spaces between the solid particles near the surface of evaporation and the difference between the amount of evaporated water and the amount of water transferred from inside the mixture to ...
