In pursuits of sustainable infrastructure, development of Low Carbon Concrete (LCC) is vital for the construction of Low Carbon Structures (LCS). For LCS to be widely applied, it is imperative that LCC exhibits the required mechanical and durability characteristics. This necessitates an understanding of constituents such as supplementary cementitious materials (SCMs), recycled aggregates (RA) and fibres that influence LCC mechanical and durability behaviours. However, based on materials characterisation, previous studies reveal significant variations in LCC mechanical properties and durability behaviours. Therefore, this review seeks to comprehend the effect of different types of SCMs, RA and fibres on key mechanical properties and durability behaviours of LCC. It also provides insights on improving LCC mechanical properties and durability behaviours, drawing from extensive research outlooks on materials characterisations, mix proportioning and curing conditions and summarises existing literature on LCC carbon footprint analysis. Finally, it identifies potential research directions for future studies including analytical models to enhance the mechanical properties and durability behaviours of LCC. • A comprehensive literature review on low carbon concrete (LCC) is presented. • The review covers both mechanical properties and durability performance of LCC. • Review on carbon footprint analysis of LCC also included. • Gaps of knowledge and potential future research directions are identified.
