摘要：

This study investigates effect of addition of ground recycled tyre on ammonium nitrate exposed specimens by performing a significant number of unconfined compressive strength (UCS) tests when cured at different curing periods. The results showed that addition of ground recycled tyre enhanced UCS values of control and exposed specimens for all three curing periods. The microstructural analysis encompasses XRD and SEM analysis conducted on the samples and the results showed that exposure of the specimens to the ammonium nitrate cause formation of a poor connection amongst soil, cement, and ground recycled tyre particles and a reduction on hydration product generation of the cement. The results of this study showed that the ground recycled tyre is an effective replacement for cement and can successfully applied while cement contribution is reduced, and strength of the specimens have not been compromised.
