ROCARE - Roman Cements for Architectural Restoration to New High Standards
focus of activity
Architecture (Fine Arts/Design), Conservation and Restoration, Chemical process engineering
ROCARE is a Collaborative Project funded within the 7th Framework Programme of the European Commission (Call identifier FP7-ENV-2008-1, Project number 226898). Roman cements represent an almost forgotten group of highly hydraulic binders of Europe’s built heritage from the 19th/early 20th centuries. The material had contributed to decorate building exteriors in a large number of European cities and towns. For the project duration of 09/2009 till 08/2012, 14 partners from 7 European countries – SMEs, industrial companies, universities, as well as public and private research institutes - join together in the re-introduction of the so-called Roman cement technology. Our aim is to combine knowledge of this historically well established binder with modern aspects of its manufacture, use and marketing. Our main target is the huge stock of buildings originating from the historicism, art nouveau and early modernism representing a period of rapid urban growth in most of Europe. Highly hydraulic binders, known as natural or Roman cements, were key materials to cover façades of buildings of the European Historicism and Art Nouveau (19th/early 20th century), a period of rapid urban growth in Europe. The maintenance, restoration and reconstruction of historic Roman cement façades form therefore an important issue in Europe’s efforts to preserve its architectural heritage. Therefore, the ROCARE project is proposed to provide conditions for the industrial development and commercialisation of Roman cements which is an innovative, promising technology developed at the level of a pilot-scale prototype in the recent research project of the 5th Framework Programme ROCEM, 2003-2006. The increasing awareness of the conservation profession and their interest in the product call now for further actions encompassed by the proposed ROCARE-project, which aim at filling gaps in knowledge and reducing the entry barriers of the novel technology to the market. They include (a) scaling up of the RC technology to a competitive level by optimising the process technologies at various conditions of production, (b) laboratory tests and studies to fully understand cement hydration and property development, as well as optimum conditions of mortar processing and handling in the conservation practice, and (c) broad dissemination measures to enlarge the market potential of the technology. The proposed project is designed for three-year duration and is jointly conducted by 14 partners from industry, SMEs and research centres in 7 countries. It will allow the prototype developed in the earlier project to establish itself on the European market of building construction.
