Mitigating the Drying Shrinkage and Autogenous Shrinkage of Alkali-Activated Slag by NaAlO2. [PDF]
Materials (Basel), 2020 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 CARDIFRCRTM [PDF]
Durability requirements have become a major issue in the design of concrete structures today. The hardening process plays a key role in the quality of the concrete. Autogenous shrinkage is considered to be a factor that may cause damage to the concrete structure during hardening.

Autogenous Shrinkage Revisited [PDF]
, 2020 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]. Within this decade suitable measurement techniques to identify autogenous deformation were developed, a large amount of scientific studies on the phenomenon were ...

Autogenous shrinkage in cementitious systems [PDF]
, 2009 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 high performance concrete mixtures are also responsible for the development of autogenous shrinkage ...

Early age autogenous shrinkage of concrete: Dissertation
, 2001 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. In reality, a volume change commences immediately after the cement and water come in contact during concrete mixing.

Effect of Supplementary Materials on the Autogenous Shrinkage of Cement Paste. [PDF]
Materials (Basel), 2020 In recent years more and more attention has been given to autogenous shrinkage due to the increasing use of high-performance concrete, which always contains supplementary materials. With the addition of supplementary materials—e.g., fly ash and blast furnace slag—internal relative humidity, chemical shrinkage and mechanical properties of cement paste ...
