, 2021 The high cement content of high-performance concrete (HPC) results in improved strength, but also in large shrinkage. The substitution of natural aggregates (NA) with recycled aggregates (RA) notably affects these properties in conventional concrete ...

Characteristics of Restrained Drying Shrinkage on Arched Steel Fiber-Reinforced Concrete
Applied Sciences, 2021 The volumetric changes of concrete, including drying shrinkage, are effectively controlled in steel fiber-reinforced concrete (SFRC) mixtures due to the action of the included steel fiber.

Cement and Concrete Research, 2021 Cementitious materials shrink when exposed to decreasing relative humidities, which may result in cracking. Shrinkage reducing admixtures (SRAs) can be used to reduce this drying shrinkage.

Agriculture, 2022 Soil shrink–swell behavior is a common phenomenon in farmland, which usually alters the process of water and solute migration in soil. In this paper, we report on a phenomenological investigation aimed at exploring the impact of drying–wetting cycles on ...

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.

Influence of different hot air drying temperatures on drying kinetics, shrinkage, and colour of persimmon slices [PDF]
, 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.

On the Shrinkage and Stiffening of a Cellulose Sponge Upon Drying [PDF]
Journal of Applied Mechanics, 2013 Everyone can observe the peculiar effect of water on a sponge: upon drying, a sponge shrinks and stiffens; it swells and softens upon wetting. In this work, we aim to explain and model this behavior by using the Biot–Coussy poromechanical framework. We measure the volume and the bulk modulus of sponges at different water contents.
