The combined use of seawater and recycled tire aggregate (RTA) in concrete is potentially a way forward towards sustainable construction. It can help control harvesting natural aggregates, manage waste tires, mitigate freshwater consumption desalination impacts. current paper aims at investigating the material performance cost effectiveness mixed with RTA. consists two parts. first part studies characteristics (fresh hardened) Thirteen mixtures, varying mixing water (seawater/freshwater) as well fine coarse aggregates (at 0%, 5%, 10%, 20% replacement levels), were investigated. An extensive experimental program was conducted to compare thirteen mixtures terms physical properties, workability, strength, absorption, chloride permeability. second performs life cycle analysis (LCCA) for 20-story building over 100-year period verify proposed that combines seawater, RTA 5% level), glass fiber-reinforced polymer (GFRP) reinforcement. A sensitivity performed investigate effect discount rate on LCCA results.
