Modelling the impact of climat change on a novel Irish Concrete Bridge

This paper assesses the impact of climate change on novel repair Ferrycarrig Bridge, a reinforced concrete (RC) marine bridge Ireland’s south-east coast. Five unique solutions were applied to seven crosshead beams Bridge during works in 2007. The two under examination herein involved replacement around sides with either 100% Ordinary Portland Cement (OPC) or which 60% cement was made up Ground Granulated Blast Furnace Slag (GGBS) and 40% OPC. Changes environmental policy mean that use GGBS within RC structures is becoming increasingly popular. Thus, understanding its performance over time imperative. Chloride ingress crack modelling are completed compare how will affect service life OPC OPC+GGBS applied. results stemming from this used quantify reinforcement corrosion deterioration beams’ structural capacity. findings indicate without consideration change, solution utilised 4.75 times more resistant severe cracking caused by chloride-induced than solution. However, durability adversely affected lifetime reduction 15.8% for worst scenario as compared just 2.7% concrete, reducing relative merit 4.11.
