<p>This review investigates the combined effects of Alccofine and steel fibres on the strength and durability characteristics of binary concrete mixes, with particular attention to crack resistance and temperature resilience. The partial replacement of cement with Alccofine, a highly reactive pozzolanic material, enhances the mechanical performance of concrete while reducing susceptibility to cracking. Concurrently, the incorporation of steel fibres significantly improves the ductility and crack-arresting capabilities of the composite. Experimental data indicate that a mix containing 15% Alccofine and 1.5% steel fibres achieves notable improvements in mechanical properties—compressive strength by up to 47%, flexural strength by 35%, and split tensile strength by 40%—compared to conventional concrete. Moreover, Alccofine contributes to enhanced resistance against chloride ion penetration and sulphate attack, while steel fibres offer improved resistance to freeze-thaw cycles. Despite these promising outcomes, the review highlights the necessity for further research to optimize the performance and field applicability of Alccofine–steel fibre reinforced concrete across diverse environmental conditions. Advancing this line of study is essential for the development of practical guidelines and standards to facilitate the effective implementation of this innovative material in the construction industry.</p>
