Recently, sustainable green binders became mandatory for the construction industry. The process of cement production is responsible for a considerable portion of CO2 causing global warming. Clinker substitution using available by-products is one of the promising strategies to cut down the CO2 emissions of the cement industry. Yet, it is challenging to limit the emission of CO2 without negatively affecting the strength and durability of the proposed concrete. One of the proposed green binders is Limestone-Calcined Clay cement (LC3). The newly developed LC3 binder integrates the advantages of incorporating available cement replacement materials - clay and limestone – and attaining adequate mechanical, physical, and durability performance. In this paper, an intensive review of previous research in LC3-based construction materials including nanomodification, fiber reinforcement, and durability enhancement is presented in details, aiming to highlight the points that lack investigation and the recommended future work.
