European experience with seawater concrete

Abstract

The use of seawater for concrete production is not common also in Europe now, even for the production of plain concrete exposed to a marine environment. However, in recent decades, certain international and national seawater concrete research projects have been initiated in Europe, including the Roman Maritime Concrete Study (ROMACONS), Sustainable Concrete using Seawater, Salt-contaminated Aggregates, and Non-corrosive Reinforcement (SEACON) and Eco-efficient By-products Suitable for the Market through the Integration of Recycling in Port Environments (SEA MIRENP). Both ROMACONS and SEACON were jointly carried out by European and non-European researchers. In both projects, actual-scale structures were analyzed. The researcher from Universitat Politeècnica de Catalunya (UPC, Barcelona TECH) developed the SEA MIRENP project and carried out actual scale tests at Barcelona Port. This outlines these three projects and describes the actual scale application of concrete produced using seawater for the marine environment as implemented in Europe as part of the projects.
