Dredged marine sand in concrete: An experimental section of a harbor pavement

This research work describes three experimental sections of a harbor pavement made with three different concretes. The influence of dredged marine sand (DMS) from Port of Sant Caries de la Rapita (Tarragona, Spain) as a fine aggregate on the production of concretes was analyzed, and its properties were determined. The three concretes were produced at a homologated plant (UNILAND): C1 (control concrete), C2 (concrete made with DMS as corrective fine sand) and C3 (concrete made with DMS as corrective fine sand and reinforced with plastic fibers PF). The fresh and hardened properties of concretes made with DMS approached the results of the control concrete. (c) 2009 Elsevier Ltd. All rights reserved.
