“…The slightly higher density of this by-product in comparison with other alternative products can be seen as either an advantage or a disadvantage. Its superficial roughness and high density are disadvantageous for highworkability concretes, although this problem can be solved by correct dosing of the fines content in the concrete mix [33,34]. This high density is also a drawback for EAFS concrete elements to be self-supported or supported by other structural elements.…”

“…The samples exhibited average Vp values of about 2300 m/s The average capillarity absorption coefficient (C) is about 27.75 g/m 2 s 0.5 , corresponding to an amount of water absorbed of about 15% typical of mortars. All the samples demonstrated a remarkably swift imbibition during the initial 60 min of the test, as the largest porosities became saturated through contact immediately [13,[34][35][36]. In addition, IC, P and ρ showed typical values for the mortar [37].…”

Mortar Characterization of Historical Masonry Damaged by Riverbank Failure: The Case of Lungarno Torrigiani (Florence)

The research of structural masonry associated with geo-hydrological hazards in Cultural Heritage is a multidisciplinary issue, requiring consideration of several aspects including the characterization of used materials. On 25 May 2016, loss of water from the subterranean pipes and of the aqueduct caused an Arno riverbank failure damaging a 100 m long portion of the historical embankment wall of Lungarno Torrigiani in Florence. The historical masonry was built from 1854–1855 by Giuseppe Poggi and represents a historical example of an engineering approach to riverbank construction, composed of a scarp massive wall on foundation piles, with a rubble masonry internal core. The failure event caused only a cusp-shaped deformation to the wall without any shattering or toppling. A complete characterization of the mortars was performed to identify the technologies, raw materials and state of conservation in order to understand why the wall has not collapsed. Indeed, the mortars utilized influenced the structural behavior of masonry, and their characterization was fundamental to improve the knowledge of mechanical properties of civil architectural heritage walls. Therefore, the aim of this research was to analyze the mortars from mineralogical–petrographic, physical and mechanical points of view, to evaluate the contribution of the materials to damage events. Moreover, the results of this study helped to identify compatible project solutions for the installation of hydraulically and statically functional structures to contain the riverbank.

“…Os valores de E obtidos com todas as metodologias usadas neste estudo são relativamente semelhantes uns aos outros. Ao comparar os resultados de todas as amostras, veri"ica-se uma mesma tendência de resultados, em que os valores de módulo dinâmico (obtido por ensaio vibracional) são mais elevados do que os de módulo de elasticidade estático, assim como reportado na literatura(Aragon et al, 2019;Marques et al, 2020).

Ensaios não destrutivos têm sido utilizados para caracterização viscoelástica de misturas asfálicas. Assim, foi desenvolvido na Universidade Federal do Ceará um teste de ressonância por impacto, que se destina a aplicações em materiais asfálticos, sendo a sua montagem e os primeiros resultados o objeto deste artigo. Na etapa de validação do novo ensaio, testes em materiais elásticos lineares foram realizados, sendo uma amostra de aço e três de argamassa. Os materiais foram submetidos a ensaios clássicos quase-estáticos de rigidez e ao ensaio dinâmico de ressonância por impacto desenvolvido. Os resultados apontam uma pequena diferença entre os valores de módulo dos dois ensaios, 2,15% para o aço e entre 4-13% para a argamassa. O teste proposto produz resultados de ressonância interpretáveis e tem potencial para ser utilizado para determinar as propriedades viscoelásticas de materiais betuminosos.
