Evaluation of field concrete deterioration under real conditions of seawater attack

Abstract In order to study the long term behavior of concrete structures under the natural exposure to aggressive seawater attack, concrete samples are taken from the wave’s repellent blocks at seashore in the north coast of the Mediterranean Sea. The samples cover a wide range of various exposure times differ from 4 years to more than 60 years. The samples composed from diverse concrete constituents and obtained from different locations along the seashore. The tests (XRF, SEM, EDX, water soluble chloride content using photometer techniques) where conducted on the extracted concretes.
