Autogenous shrinkage revisited [PDF]
In the 1990s it became generally accepted in the scientific community that autogenous shrinkage is a major reason for cracking observed during hardening of high-performance concrete [1, 2].

Autogenous shrinkage of alkali-activated slag: A critical review [PDF]
This paper provides a critical review on autogenous shrinkage of alkali-activated slag (AAS). It is reported that AAS paste, mortar, and concrete generally show larger autogenous shrinkage than Portland cement (PC) counterparts.

Mitigating the Drying Shrinkage and Autogenous Shrinkage of Alkali-Activated Slag by NaAlO2 [PDF]
The shrinkage of alkali-activated slag (AAS) is obviously higher than ordinary Portland cement, which limited its application in engineering. In this study, the effects of NaAlO2 in mitigating drying shrinkage and autogenous shrinkage of AAS were studied.

Autogenous shrinkage of high performance concrete: A review
Autogenous shrinkage is a major concern in early age cracking of high performance concrete (HPC). Low water-to-binder ratio and incorporation of supplementary cementitious materials (SCMs) can remarkably affect the pore structure, relative humidity, self-

Autogenous shrinkage in cementitious systems
Autogenous shrinkage is of concern in high performance concrete mixtures, when specific properties like strength and durability are enhanced. Factors like low watercement ratio, low porosity and increased hydration kinetics which are associated with ...

Early age autogenous shrinkage of concrete:Dissertation
Volume change of concrete resulting from structural and environmental factors is an acceptable phenomenon. In the majority of cases this volume change, or shrinkage, is assumed to begin at the time of loading or drying.

Autogenous Shrinkage of Concrete at Early Ages [PDF]
© 2020, Springer Nature Singapore Pte Ltd. High Performance Concrete (HPC), particularly high strength concrete mixes (60–100 MPa) containing high cementitious content and low w/b ratios (0.40–0.25) is used for some precast elements.

Mitigation strategies for autogenous shrinkage cracking
As the use of high-performance concrete has increased, problems with early-age cracking have become prominent. The reduction in water-to-cement ratio, the incorporation of silica fume, and the increase in binder content of high-performance concretes all ...

Analysis of Autogenous and Drying Shrinkage of Concrete [PDF]
Concrete undergoes volume change as it changes phases from plastic to solid. Volume change due to water movement and losses within the concrete are referred to as chemical and autogenous shrinkage and drying and plastic shrinkage are due to water ...
