To mitigate environmental impacts and increase energy efficiency in the cement production process, alternative materials to clinker are now used in cement, allowing for the production of a larger amount of composite cement with identical properties from a certain amount of clinker produced by the cement factory. This is achieved through the appropriate combination of low-carbon and environmentally friendly materials. The aim is to produce cement that not only uses accessible resources but also reduces carbon emissions. In this study, recycled minerals (recycled clay (RC) and ground granulated blast-furnace slag (GG)), calcined clay (CC), and limestone (LS) powder were used as partial replacements for cement/clinker to create low-carbon cement. The properties of fresh mortar and compressive strength tests were considered. Accordingly, 16 mix designs were prepared, including 5 mortar mix designs containing CC, LS powder, and recycled materials as a cement replacement, and 9 mix designs containing CC, LS powder, and recycled materials as a clinker powder replacement, along with two reference mixes. The results showed that the compressive strength of the mixes containing RC at different ages was similar to that of mixes containing CC. Based on the results, the compressive strength of the mixes containing RC and LS with 30% replacement decreased by about 20% compared to the reference mix. Meanwhile, the reduction in compressive strength of the 35% replacement mixes containing recycled minerals was less than 10%.
