Modeling of frost salt scaling
WebA search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying τ-lepton is presented. Two exclusive final states with either exactly one or at least two τ-leptons are considered. The analysis is based on proton-proton collisions at s=13 TeV corresponding to an integrated luminosity of 36.1 fb-1 delivered by … Web11 jun. 2024 · Due to having insufficient knowledge about the phenomenon, modeling attempts have been restricted to black-box type [7] . However, recently an interesting theoretical explanation of the mechanism of frost salt attack was introduced by Valenza and Scherer [8,9] . The researchers proposed a mechanism called glue-spall .

Web1 feb. 2010 · Salt scaling is a type of superficial damage that occurs when the surface of concrete is exposed to ice and salt (or other solute) [1]. The phenomenology of scaling has been extensively reviewed [2], [3], [4] and a theory, called the “glue-spall” model, has been proposed that seems to account for most of the observations [5]. WebA great deal of information has been collected over the years about the phenomenology of salt scaling of concrete, and no single mechanism has been identified that can account …

This method consists of confining a pool of 3 wt% NaCl solution with a depth of 6 mm on the surface of a concrete slab whose thickness is ≥ 75 mm (Fig. 2).
Web30 mrt. 2024 · The method that was used in the model of Schlangen and van Mier was the discrete element approach, in which the material is discretised as a network of small beam elements. All these single elements are linear elastic and have brittle fracture behaviour once the stress reaches a predefined strength.
