Autogenous shrinkage and drying shrinkage of recycled aggregate concrete: A review

Journal of Cleaner Production, 2021
Abstract This paper comprehensively reviews the factors influencing the autogenous shrinkage and drying shrinkage of recycled aggregate concrete (RAC). Compared with natural aggregate concrete (NAC), RAC has a lower autogenous shrinkage because of the internal curing effect of recycled concrete aggregate (RCA). However, the internal curing efficiency

Drying shrinkage behavior of hybrid alkali activated cement (HAAC) mortars

Construction and Building Materials, 2022
Shrinkage is a vital factor for hybrid alkali activated cement (HAAC) related to durability. In this work, the drying shrinkage behavior of HAAC mortars with various precursors, curing regimes and activator states was investigated. Portland cement mortar

Drying shrinkage and stresses

, 1992
A numerical study of the effects of shrinkage and stresses on drying kinetics was performed. A diffusional model was used, taking into account the deformation of the solid. The materials studied were a medium-shrinkage clay and a highly shrinking gel.

Structural Effects of Drying Shrinkage

Journal of Engineering Mechanics, 2005
Predicting delayed strains in concrete proves to be critical to a large number of prestressed concrete structures. These delayed strains include drying shrinkage, basic, and drying creep strains essentially. In this paper, a model for identifying structural effects, due to cracking, on the behavior of drying concrete is presented. Existing experimental

Drying Shrinkage Mitigation

2020
This chapter focuses on understanding the drying shrinkage phenomenon and the mechanism that leads to cracking of concrete. The recent trends to increase the cementitious content of concrete, requiring high performance for bridge decks and highway pavement overlays, are prone to shrinkage and potential cracking.
