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 . WebThis paper discusses the numerical modeling of deterioration in cement-based materials due to frost salt scaling (FSS). Several aspects of FSS are investigated such as carbonation, microstructure, mechanical properties and testing conditions. Mainly blast-furnace slag cement (henceforth slag cement) systems are of interest in this paper since …

Schlangen Published 2008 Materials Science, Engineering Cement and Concrete Research View via Publisher Save to … WebOn the basis of the microscopic 3D image data, we formulated percolation-based models of macroscopic properties (e.g., strength, thermal expansion coefficient, porosity metrics) relevant for different proposed frost salt scaling mechanisms. Model results and observations suggest that the ice growth velocity, direction and confinement, have a ...
Web8 mei 2006 · It was observed that frost salt scaling attack generates cracks in the microstructure which adhere to slag-matrix interfacial zones. This was confirmed by nano-indentation tests which demonstrated that carbonation creates a significant number of weak zones in the slag cement paste. 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 …
