Recycled aggregates derived from excavation materials — mechanical performance and identification of weak minerals
2022
AbstractThe present study investigates the mechanical performance of recycled aggregates derived from excavation materials (REM). REM is blended with different quantities of recycled phyllite materials (RPM) and is investigated by Los Angeles (LA) and micro-Deval (MD) tests. X-ray diffraction (XRD) and acid solubility test are performed on the pulverized fractions < 1.6 mm obtained from the LA and MD tests to assess the respective degree of fragmentation and wear of mineral components. The results of the materials in unblended conditions showed considerable difference between MD performance while similar performance was found for LA. Furthermore, about 40% of RPM was sufficient to blend …
Torre del Greco, villa marittima in contrada Sora (?): 76. Statuetta di corridore
2019
Si dà la prima edizione di una statuetta appartenente alla "seconda donazione borbonica" confluita nel Museo di Palermo, finora considerata solo nel repertorio fogografico della scultura antica di Arndt e Bruckmann, ma con interpretazione inesatta del soggetto. Si tratta di una rara rappresentazione a tutto tondo di un atleta in atto di doppiare la meta, forse in origine appartenente all'arredo scultoreo della Villa marittima di Contrada Sora.
Selinunt, Sizilien. Forschungen in Selinunt, Teil 1. Ein neues Modell für die Stadt Selinunt. Die Feldarbeiten des Jahres 2021
2022
Since 2021, the German Research Foundation has been funding a new interdisciplinary field project to investigate the urban fabric of the Greek colony of Selinous in a spatially comprehensive and diachronic perspective. The project aims at extending the existing model of the ideal Greek city by considering also the historically conditioned fractures in the urban development and the multiple transformations of the living space between the 7th and 3rd century BCE. This is to be pursued by large scale archaeological, geophysical and geoarchaeological prospections, small excavations in selected areas and the thorough study of the finds and archaeobiological remains. This is a report about the fi…
ANALISI DEL PROCESSO DI ROTTURA PER SOLLEVAMENTO DEL FONDO DI SCAVI CONTROVENTATI
2012
Nella presente nota si riportano i principali risultati di un’analisi sui meccanismi di rottura per sollevamento del fondo di scavi sostenuti da diaframmi. È stata studiata l’influenza su tali meccanismi di fattori quali: lo stato tensionale iniziale; il rapporto tra larghezza e altezza dello scavo; la profondità d’infissione dei diaframmi al di sotto del fondo dello scavo; la dissipazione delle sovrappressioni interstiziali. I risultati ottenuti indicano che i metodi correntemente utilizzati per la valutazione delle condizioni di stabilità del fondo scavo, basati sull’analisi in termini di tensioni totali e sull’impiego della resistenza non drenata su possono portare a sopravvalutare le co…
Contrary motion. From countryside to city, from city to countryside
2015
Within the general strategy of the projects coordinated by Sandro Rolla and Marina Tornatora, the project of “Land” thematic pavilion is settled on the edge of Piacenza south expansion. The main idea is that, operating by meaningful fragments, the specific intervention is able to generate long term and wide-range transformations, overcrossing the specific area limits and having an effect on a territory scale. It focuses on the main issue of the peri-urban space, whose ambiguity has been at the center of contemporary architectural debate. This is approached by the design of the soil, in order to tie up areas of the city and make them the enhancement key of the future urban development. The p…
Baucina (Pa) - Monte Falcone 2014. Indagini nella necropoli
2017
The aim of this report is to present the results of rescue excavations, executed in order to contrast illegal excavation at the necropolis at Baucina, in northwestern Sicily, where Punic, Greek and indigenous traditions coexisted. Their relationship is the focus of the ongoing research. The archaeological dataset demonstrates that the interaction between three different ethnicities resulted in an impressive variety of rituals.
Repeated Load Triaxial Testing of Recycled Excavation Materials Blended with Recycled Phyllite Materials
2022
Recycled Excavation Materials (REM) are becoming viable alternative construction resources due to their economic benefits. However, REM may be composed of weak rocks, e.g., phyllites, limiting the use in a base layer. The present paper attempts to further the knowledge of the mechanical performance of REM by performing Repeated Load Triaxial Tests (RLTT). REM are mixed with Recycled Phyllite Materials (RPM) in systematic blends of 0%, 25%, 50%, and 100%. The batches’ resilient modulus (MR) and permanent deformation (PD) characteristics were assessed to establish the maximum RPM allowed into REM while maintaining the required performance. Hicks and Monismith’s and Uzan’s mo…
The excavations at tell el-‘Abd
2019
This volume (marru 5/2) is dedicated to the small finds from Tell el-ʻAbd and to the results of environmental studies (archaeobotany, archaeozoology and anthracology); it continues the final publication of the excavation, which began in 2014 with the presentation of the 3rd-millennium ceramics (AVO 16/2). In that volume, the author, Paola Sconzo, introduced the tell as well as the history and the methodology of its excavation. At present, that is, before the final review of the architecture and the stratigraphy, her statements are still fully valid, and have therefore in the main been inserted under 1.1 The excavations at Tell el-ʻAbd.
Evaluating the effect of mineralogy and mechanical stability of recycled excavation materials by Los Angeles and micro-Deval test
2021
This paper presents the findings of the mechanical performance of recycled excavation materials (REM). The aim was to document the stable performance of REM and to suggest its suitability for unbound applications. Test operations were performed at different schedules with the Los Angeles (LA) and micro-Deval (MD) test machine. X-ray diffraction (XRD) analysis was performed to examine the effect of mineralogy on the performance of REM. The results showed that REM showed consistent LA performance, but significant variations were observed in MD values. XRD results showed that up to 20% of chlorite and mica minerals had no influence on the LA performance of REM.
Relazioni tra geomorfologia, processi post-deposizionali e visibilità del suolo nella lettura dei dati di prospezione archeologica
2005
This paper takes into examination two different districts of the vast area investigated by the archaeological survey of the hinterland of the Greek colony of Himera: the coastal area between the northern Imera and Roccella rivers and the hilly watershed zone located between the northern Imera, southern Imera and Platani rivers. The study examines the relationship between geomorphology, post-depositional processes and visibility of the ground and their impact on the interpration of data collected during the archaeological survey and, consequently, on the historical reconstruction of the population of the territory from Prehistory to the Middle Ages. Three aspects have been taken into conside…
