Modelling the Severity of Plastic Shrinkage in Cementitious Materials [PDF]

open access: yesProceedings of the International Conference on Civil Infrastructure and Construction (CIC 2020), 2020
"Plastic shrinkage cracking in cement-based materials occurs between the mixing and the final setting of the mixture, where rapid evaporation of the mixed water is the main cause behind the phenomenon. The induced cracks may impair the durability and sustainability of the structure by facilitating ingress of harmful materials into the concrete bulk. In

Development of eco-friendly engineered cementitious composites using glass aggregates: Shrinkage properties

open access: yesCleaner Engineering and Technology, 2021
Generally, the absence of coarse aggregate coupled with high binder content in engineered cementitious composites (ECC) mixtures subjects it to high shrinkage despite the presence of fibres.

Early structure formation of foam concrete mix containing modifying admixture

open access: yesИнженерно-строительный журнал, 2015
Cement based foam concrete of natural aging experiences high shrinkage of foam concrete mix in the formwork and shrinkage strain when drying. When managing the microstructure of the composite, namely the change (acceleration) of the microstructure ...

Plastic shrinkage cracking of concrete − roles of osmotic suction [PDF]

open access: yesMagazine of Concrete Research, 2011
Plastic shrinkage cracking of concrete occurs when the stresses arising in the concrete, due to a combination of suction and restraints of deformation such as reinforcement or formwork, equal its strength. However, three different types of suctions should be distinguished, namely total, matric and osmotic suctions.

Effect of steel fibers on plastic shrinkage cracking of normal and high strength concretes

open access: yesMaterials Research, 2010
Naturally concrete shrinks when it is subjected to a drying environment. If this shrinkage is restrained, tensile stresses develop and concrete may crack. Plastic shrinkage cracks are especially harmful on slabs.

Some Geotechnical Properties of Plastic Soil Enhanced with Cement Dust

open access: yesJournal of Engineering, 2021
Plastic soil exhibits unfavorited geotechnical properties (when saturation), which causes negative defects to engineering structures. Different attempts (included various materials) were conducted to proffer solutions to such defects by experimenting in ...

The effect of fibers on the loss of water by evaporation and shrinkage of concrete

open access: yesRevista IBRACON de Estruturas e Materiais
Shrinkage is one of the least desirable attributes in concrete. Large areas of exposed concrete surfaces , such as in shotcrete tunnel linings, where it is practically impossible to make a moist cure, are highly susceptible to plastic shrinkage at early ...
