Prediction equation of drying shrinkage of concrete based on composite model

Drying shrinkage and microstructure characteristics of mortar incorporating ground granulated blast furnace slag and shrinkage reducing admixture

“…Drying shrinkage, which is one of the major causes of the cracks generated in concrete structures [1], can be defined as the volumetric change due to the drying of concrete. This change in volume of the concrete is related to the volume of water lost.…”

Prediction of Shrinkage of Concrete Containing Fly Ash and/or Silica Fume Using Composite Modeling

“…The aggregates are assumed to have negligible shrinkage strain values as they mainly restrain the shrinkage of the concrete. The composite model is based on the formulae provided by Eguchi and Teranishi (2005) from the works of Kishitani and Baba (1975). For our study, the two-step equation can be re-written as:…”

“…Keeping this in mind, the ACI 209R-92 committee recommends further study on effects of chemical and mineral admixtures on concrete shrinkage. It is worth mentioning here that, the concept of two-step composite model was proposed by Eguchi and Teranishi (2005) to study the drying shrinkage strain and Young's Modulus for ordinary concrete and mortar. However, no systematic studies are available to predict the shrinkage of concrete from paste level to large scale coupon level incorporating different types, quantities, and combinations of mineral admixtures such as fly ash and silica fume.…”

Development and Performance Assessment of the High-Performance Shrinkage Reducing Agent for Concrete

“…Cracks caused by drying shrinkage are considered inevitable in concrete structures. When drying shrinkage occurs, cracks form in concrete structures due to the imbalance of contractile force and the binding force of concrete [8].…”
