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.

Discussing Different Approaches for the Time-Zero as Start for Autogenous Shrinkage in Cement Pastes Containing Superabsorbent Polymers. [PDF]
Materials (Basel), 2019 Many studies have already been published concerning autogenous shrinkage in cementitious materials. Still, no consensus can be found in the literature regarding the determination of the time-zero to initiate the recording of autogenous shrinkage.

Shrinkage of mortar with the addition of wood biomass ash and recycled tyre polymer fibres
Građevinar, 2023 In this paper, the possible synergistic effects of fly wood biomass ash (WBA) and recycled tire polymer fibres (RTPF) on long-term autogenous shrinkage and drying shrinkage in mortar were investigated, and the pore structures of mortar specimens with WBA

Cracking risk of high-performance cement composites due to restrained autogenous shrinkage with and without soaked lightweight aggregate [PDF]
Archives of Civil Engineering, 2023 Due to the large amount of binder and low water-cement ratio, high-performance cement composites have high compressive strength and a dense hardened cement paste microstructure.

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 ...

Crack mitigation in concrete : superabsorbent polymers as key to success? [PDF]
, 2017 Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these

Influence of autogenous shrinkage on mass transport properties of concrete
Maskana, 2016 Autogenous shrinkage in concrete is defined as the change of volume after initial setting occurs. It develops at very early ages as a result of chemical shrinkage and self-desiccation effect.
