Thesis (PhD(Civil Engineering))--University of South Australia, 2022. Includes bibliographical references (pages 243-251) Rubber particles made from end-of-life tyres have gained popularity as a potential replacement for aggregate in concrete. All researchers found that rubber particles reduced the compressive strength of the concrete. This has led to few researchers considering the durability properties of rubberised concrete. The limited studies on its durability properties in existing literature have found conflicting results. This thesis focused on the durability of concrete using Crumbed Rubber particles as a replacement for the fine aggregate. A total of 27 mix designs were tested using four different durability tests. This research has shown that the inclusion of rubber did not negatively impact the chloride or carbon dioxide ingress of the concrete mixes tested. However, the rubber did have a slight negative impact on water sorptivity and a more significant negative impact on abrasion resistance.
