The Committee on Ancient Roman Concrete, JSCE (Com-No. 114) Mt. Vesuvius The Committee on Roman Concrete (Com-No. 114) is one of the special subcommittees in the Concrete Committee, Japan Society of Civil Engineers (JSCE). This committee has been chaired by Prof. E. Sakai, Tokyo Institute of Technology, and advanced by seven active members. Also, this committee is supervised by Dr. M. Aoyagi, Director-general of the National Museum of Western Art of Japan and Dr. Matsuyama, University of Tokyo. Pompeii The purpose of this committee is to investigate the long-term durability of concrete, focusing especially on the material phase. In addition, the important mission of this committee is to reflect the results of these investigations for the development of society, public welfare, growth of civil engineering, and concrete engineering. This committee also relates to the standard specifications for design and construction of concrete structures such as huge concrete structures for storage of nuclear waste which Ancient Roman Concrete in Pompeii greatly require long-term durability performance. It is well known that concrete deteriorates due to rain, CO2 in the air, and chloride ion in seawater. Therefore, the properties of concrete remarkably change due to their long history of exposure condition, although their performances were the same at the initial stage. From these viewpoints, it is quite important to collect as much aged concrete samples as possible. Ancient Roman concrete would Huge concrete structures for storage of surely contain many useful and important nuclear waste in Japan information.

In This Study, Marcello Mogetta Examines the Origins and Early Dissemina- Tion of Concrete Technology in Roman Republican Architecture
Cambridge University Press 978-1-108-84568-7 — The Origins of Concrete Construction in Roman Architecture Marcello Mogetta Frontmatter More Information THE ORIGINS OF CONCRETE CONSTRUCTION IN ROMAN ARCHITECTURE In this study, Marcello Mogetta examines the origins and early dissemina- tion of concrete technology in Roman Republican architecture. Framing the genesis of innovative building processes and techniques within the context of Rome’s early expansion, he traces technological change in monumental construction in long-established urban centers and new Roman colonial cites founded in the 2nd century BCE in central Italy. Mogetta weaves together excavation data from both public monu- ments and private domestic architecture that previously have been studied in isolation. Highlighting the organization of the building industry, he also explores the political motivations and cultural aspirations of patrons of monumental architecture, reconstructing how they negotiated economic and logistical constraints by drawing from both local traditions and long- distance networks. By incorporating the available scientiﬁc evidence into the development of concrete technology, Mogetta also demonstrates the contributions of anonymous builders and contractors, shining a light on their ability to exploit locally available resources. marcello mogetta is a Mediterranean archaeologist whose research focuses on early Roman urbanism in Italy. He conducts primary ﬁeldwork at the sites of Gabii (Gabii Project) and Pompeii (Venus Pompeiana Project), for which he has received multiple grants from the National Endowment for the Humanities, the Loeb Classical Library Foundation, the AIA, and the Social Sciences and Humanities Research Council. He coordinates the CaLC-Rome Project, an international collaboration that applies 3D mod- eling and surface analysis to the life cycle of ceramic vessels from the Esquiline necropolis in Rome.

Brief History of the Roman Empire -Establishment of Rome in 753 BC
Brief History of the Roman Empire -Establishment of Rome in 753 BC (or 625 BC) -Etruscan domination of Rome (615-509 BC) -Roman Republic (510 BC to 23 BC) -The word 'Republic' itself comes from the Latin (the language of the Romans) words 'res publica' which mean 'public matters' or 'matters of state'. Social System -Rome knew four classes of people. -The lowest class were the slaves. They were owned by other people. They had no rights at all. -The next class were the plebeians. They were free people. But they had little say at all. -The second highest class were the equestrians (sometimes they are called the 'knights'). Their name means the 'riders', as they were given a horse to ride if they were called to fight for Rome. To be an equestrian you had to be rich. -The highest class were the nobles of Rome. They were called 'patricians'. All the real power in Rome lay with them. Emperors of the Roman Empire -Imperial Period (27BC-395AD) Augustus: Rome's first emperor. He also added many territories to the empire. Nero: He was insane. He murdered his mother and his wife and threw thousands of Christians to the lions. Titus: Before he was emperor he destroyed the great Jewish temple of Solomon in Jerusalem. Trajan: He was a great conqueror. Under his rule the empire reached its greatest extent. Diocletian: He split the empire into two pieces - a western and an eastern empire. -Imperial Period (27BC-395AD) Hadrian: He built 'Hadrian's Wall' in the north of Britain to shield the province from the northern barbarians.

Ancient Concrete Works
Ancient concrete works Amelia Carolina Sparavigna Dipartimento di Fisica Politecnico di Torino It is commonly believed that the ancient Romans were the first to create and use concrete. This is not true, as we can easily learn from the Latin literature itself. For sure, Romans were able to prepare high-quality hydraulic cements, comparable with the modern Portland cements. In this paper, we will see that the use of concrete is quite older, ranging back to the Homeric times. For instance, it was used for the floors of some courts and galleries of the Mycenaean palace at Tiryns. Introduction On April 12, 2011, in concurrence with an exhibition in the Oxford’s Ashmolean Museum of some ancient treasures of Greece, the BBC announced that Macedonians created cement three centuries before the Romans [1]. Unearthing some tombs of a royal complex belonging to Alexander the Great and his father Philip, at Vergina, archaeologists determined that Macedonians were “not only great warriors but revolutionary builders as well“, since they used concrete before the Romans. This information is quite interesting because shows the location of an early use of concrete. Unfortunately, if we want to shed light on the origin of the material, this simple comparison between Macedonian and Roman concretes is a little bit misleading. Moreover, it is raising another question: were Macedonians the first people using concrete? The answer is negative. Concrete was older even than Alexander the Great. Let me show you how we can deduce this fact from some Latin essays and their English translations and from the reports of Schliemann’s excavations of Mycenaean archaeological sites.

Introduction
Cambridge University Press 978-1-108-84568-7 — The Origins of Concrete Construction in Roman Architecture Marcello Mogetta Excerpt More Information ONE INTRODUCTION AIMS AND METHODS Concrete construction represents Rome’s major contribution to the history of ancient architecture and engineering. Scholars have touted the modern character of this man-made material, which gave planners the ability to cast structures wherever they were needed, emphasizing the inextricable link between building medium and building forms.1 Observation of the durability and longevity of concrete features, and particularly their survival in hostile environments such as seawater, has stimulated the scientiﬁc study of the material in order to identify the constituent elements and to describe the mechanical, chemical, and physical characteristics for possible reproduction.2 As a result, the systematic testing of ancient samples has greatly improved our understanding of how Roman builders of the Late Republican and Imperial periods exploited raw materials.3 Moreover, the approach has shifted to concentrate on the step-by-step examination of the construction process, and standardized procedures have been developed to quantify the costs of construction, thus allowing for a contextualization of the building industry within the broader Roman economy.4 As current scholarship shows, by teasing out the actual choices made by patrons and builders from the 1 On the concept of Rome’s architectural revolution: Lechtman and Hobbs 1987.

Delatte,1 Member, ASCE ABSTRACT: Although masonry and lime mortars had been used for centuries by earlier civilizations, the Romans were the first to extensively use naturally occurring volcanic earth to make hydraulic cement. The volcanic powder named ‘‘pulvis puteolanis,’’ found near the town of Puteoli near Naples (now Pozzouli), was used to build magnificent structures. The use of this hydraulic cement in masonry and concrete greatly expanded civil engineering possibilities. The Roman engineer Vitruvius, writing in The Ten Books on Ar chitecture, described the careful materials selection, proportioning, and workmanship that was critical to the performance of Roman concrete. Masonry and coarse and fine aggregates were carefully selected for durability.

Green Building Evaluation of the Roman Pantheon Using Fuzzy Set Concept
Green Building Evaluation of the Roman Pantheon Using Fuzzy Set Concept. THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Nina Frances Parshall, B.S. Graduate Program in Civil Engineering The Ohio State University 2016 Master's Examination Committee: Dr. Fabian Tan, Advisor Dr. Frank Croft Dr. Lisa Abrams Copyright by Nina Frances Parshall 2016 Abstract This research focuses on the ancient green building evaluation of the Roman Pantheon, use the fuzzy set concept. In today’s society and in the future, there will be pressure from society to continue to make improvements on green building design and construction, and this research aims to advance current green building evaluations. An ancient building, such as, the Roman Pantheon was used for this research because it can provide great insight to ancient design and construction practices, many of which have been forgotten over the years. The green building evaluation first begins with the evaluation of specific green building categories including Site Selection, Use of Water, Energy Conservation, Materials and Resources, Air Quality, and Innovation of Design and Construction. Each category is rated based on the subcategories, which are assigned linguistic rating values. The linguistic values range from extremely non-green to extremely green. After all linguistic ratings are assigned, a weight average is calculated to determine the category rating and the total greenness rating of the Pantheon. While the weighted average can provide a total green building rating for a structure, it does not take into account the unclearly defined linguistic expressions.

The Toughness of Imperial Roman Concrete
Fracture Mechanics of Concrete and Concrete Structures - Recent Advances in Fracture Mechanics of Concrete - B. H. Oh, et al.(eds) ⓒ 2010 Korea Concrete Institute, Seoul, ISBN 978-89-5708-180-8 The toughness of imperial roman concrete P. Brune & R. Perucchio University of Rochester, Rochester, New York, USA A.R. Ingraffea Cornell University, Ithaca, New York, USA M.D. Jackson Northern Arizona University, Flagstaff, Arizona, USA ABSTRACT: The concrete composites used to realize the monumental structures of Imperial Rome are re- markable engineering materials. While the endurance of intact constructions such as the Pantheon evinces the concretes’ durability, such durability mostly serves to preserve the mechanical properties, which are responsi- ble both for the monuments’ original creation and continued survival. Despite their prominent role in the en- gineering achievements of the empire, these mechanical properties – particularly in tension and fracture – have not been comprehensively assessed. We first review the mechanical properties obtained through various experimental programs conducted on both authentic ancient composite core samples and their components, summarizing the major findings and outlining the remaining gaps in knowledge. We then qualitatively discuss the fracture of Roman concrete within the context of our own testing program, which will test both re- fabricated and authentic materials, with the aim of characterizing the fracture behavior that has contributed to the preservation of a significant component of engineering heritage. 1 INTRODUCTION fragmented brick and volcanic rock coarse aggregate of decimeter-scale dimensions bonded by a poz- Between 60-160CE, Imperial Roman engineers zolanic mortar, based on altered volcanic ash ini- honed their usage of concrete to create spanned mo- tially mixed with hydrated lime.
