Influence of Different Hot Air Drying Temperatures on Drying Kinetics, Shrinkage, and Colour of Persimmon Slices [PDF]
Foods, 2020 Drying characteristics of persimmon, cv. “Rojo Brillante”, slabs were experimentally determined in a hot air convective drier at drying temperatures of 45, 50, 55, 60, and 65 °C at a fixed air velocity of 2.3 m/s.

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

Prediction of Drying Shrinkage of Portland Cement Paste: Influence of Shrinkage Mechanisms
Journal of King Saud University: Engineering Sciences, 1991 Ultimate drying shrinkage of paste was investigated in terms of the Gibbs-Bangham shrinkage and the capillary stress mechanisms. Shrinkage measurements and nitrogen sorption isotherms were obtained on cement pastes of water-to-cement (W/C) ratios of 0.4 ...

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.

Modeling the drying shrinkage of structural concretes
Innovative Infrastructure Solutions, 2021 Shrinkage in hydraulic materials is a complex time-dependent process. For standard concretes, one of the most considerable parts of shrinkage is drying shrinkage. In fact, to predict deformations of concrete due to shrinkage, various predictive models have been developed; most of them use many numbers of factors that can affect shrinkage such as ...

THE INFLUENCE OF SHRINKAGE ON DRYING BEHAVIOUR OF CLAYS [PDF]
Drying Technology, 1994 A correct description of the evolution of moisture concn. profiles in shrinking materials is complicated by the influence of shrinkage on mass transfer. Shrinkage has to be accounted for in the diffusion equation. Simulations have been performed for three types of shrinkage: isotropic, unidirectional and no shrinkage.

DRYING ACCOMPANIED WITH SHRINKAGE-II
NIPPON SUISAN GAKKAISHI, 1962 All of the existing theories of drying of a solid body have neglected the effect of the decrease of thickness due to the loss of water from the solid during drying. This decrease, however, seems to become noticeable for the case of fresh fish muscle.
