Experimental Study on Autogenous and Drying Shrinkage of Steel Fiber Reinforced Lightweight-Aggregate Concrete

open access: yesAdvances in Materials Science and Engineering, 2016
Steel fiber reinforced lightweight-aggregate concrete (SFRLAC) has many advantages applied in structural engineering. In this paper, the autogenous shrinkage and drying shrinkage of SFRLAC for up to 270 days were measured, considering the effects of ...

Modelling desiccation shrinkage of large structures

open access: yesEPJ Web of Conferences, 2013
Drying of cement-based materials induces drying shrinkage, which may cause prestress loss or/and cracking if strains are (self or externally) restrained.

Autogenous and drying shrinkage properties of precast recycled aggregate concrete

open access: yesCase Studies in Construction Materials
Crushing prefabricated rejects into recycled aggregates (PRAs) and recasting them forms precast recycled aggregate concrete (PRAC), which offers superior mechanical properties, durability, and cost and environmental benefits compared to conventional RAC.

Studies on the Influence of Drying Shrinkage Test Procedure, Specimen Geometry, and Boundary Conditions on Free Shrinkage

open access: yesAdvances in Materials Science and Engineering, 2017
Although considerable progress has been made in enhancing the use and interpretation of free ring shrinkage test, little is known about the impact of the test procedure, the specimen geometry, the surface area-to-volume (S/V) ratio exposed to drying, and

Reducing drying shrinkage of concrete by treatment of aggregate [PDF]

open access: yes, 2010
Drying shrinkage of concrete has been found to cause cracking, water leakage and other serviceability problems and is thus an important research topic. In early studies, it has been found that the shrinkage of concrete varies with the rock aggregate used.
