Durability of Structural Adhesive Exposed to Marine Environment
Structural adhesive plays an important role in external bonding with fibre-reinforced polymer (FRP) materials for strengthening aged steel structures. The durability of structural adhesive exposed to harsh environmental conditions has attracted much attention in recent years. Extensive work has been conducted on the performance of different structural adhesives when immersed in distilled water, salt solution, alkaline solution and so on. Several prediction models for moisture absorption and mechanical behaviour degradation have been proposed based on test data. However, the effect of chloride ion has not been well understood. This paper conducted an experimental study on the durability of structural adhesive when subjected to marine environment with a special focus on the influence of chloride ion. Two types of structural adhesive were selected. A total of 256 samples were prepared and exposed to various conditions, including simulated seawater and distilled water at 35 ℃ and 50 ℃. The moisture absorption and mechanical properties degradation of adhesive were carefully monitored. Based on the experimental data, an index was developed to represent the effect of chloride ion.
