By C.J. Brandon, M.D. Jackson

One marker of the majesty of old Rome is its surviving architectural legacy, the lovely is still of that are scattered through the circum-Mediterranean panorama. unusually, one really notable element of this background is still particularly unknown. There exists underneath the waters of the Mediterranean the actual remnants of an enormous maritime infrastructure that sustained and attached the western world’s first worldwide empire and economic climate. the main to this superb accomplishment and to the survival of constructions within the opposed surroundings of the ocean for 2 thousand years used to be maritime concrete, a construction fabric invented after which hired by means of Roman developers on a grand scale to build harbor installations anyplace they have been wanted, instead of purely in destinations with helpful geography or topography.

This ebook explains how the Romans equipped so effectively within the sea with their new invention. the tale is a stimulating mixture of archaeological, geological, historic and chemical study, with relevance to either historical and glossy know-how. It additionally breaks new floor in bridging the distance among technological know-how and the arts via integrating analytical fabrics technology, heritage, and archaeology, in addition to underwater exploration. The booklet can be of curiosity to a person attracted to Roman structure and engineering, and it'll carry unique curiosity for geologists and mineralogists learning the fabric features of pyroclastic volcanic rocks and their alteration in seawater brines. The demonstrable longevity and toughness of Roman maritime concrete buildings might be of targeted curiosity to engineers engaged on cementing fabrics acceptable for the long term garage of unsafe ingredients resembling radioactive waste.

A pioneering technique was once used to bore into maritime constructions either on land and within the sea to gather concrete cores for trying out within the learn laboratories of the CTG Italcementi workforce, a number one cement manufacturer in Italy, the collage of Berkeley, and in different places. The ensuing mechanical, chemical and actual research of 36 concrete samples taken from eleven websites in Italy and the japanese Mediterranean have helped fill many gaps in our wisdom of ways the Romans inbuilt the ocean. to realize much more wisdom of the traditional maritime expertise, the administrators of the Roman Maritime Concrete examine (ROMACONS) engaged in an bold and specific experimental archaeological venture – the development underwater of a replica of a Roman concrete pier or pila. an identical uncooked fabrics and instruments to be had to the traditional developers have been hired to provide a duplicate concrete constitution that looks to be remarkably just like the traditional one studied in the course of ROMACON’s fieldwork among 2002-2009.

This quantity unearths a notable and certain archaeological venture that highlights the synergy that now exists among the arts and technological know-how in our carrying on with efforts to appreciate the earlier. it is going to speedy develop into a customary study device for all drawn to Roman construction either within the sea and on land, and within the background and chemistry of marine concrete. The authors additionally desire that the knowledge and observations it provides will stimulate extra study through students and scholars into comparable themes, seeing that we've got much more to benefit within the years ahead.
