As the construction industry is a leading contributor to carbon emissions, innovative solutions to achieve sustainability has to be developed. The scope of this project is to highlight the potential of using ferrock, an iron-based binder material, known for its ability to absorb and sequester carbon dioxide during curing, as a sustainable substitute for ordinary Portland cement. By the replacement of cement with optimum percentage of ferrock in concrete, the proposed paver blocks can significantly reduce the carbon footprint by absorbing CO2 while enhancing mechanical properties and durability. Various literatures suggests that the optimum percentage of ferrock in concrete was 8–10% by weight of cement based on various strength and durability tests. Also, durability problems such as alkali-aggregate reactivity, sulphate & chloride attacks, reinforcement corrosion etc. can be controlled by improving the properties of conventional concrete by the incorporation of ferrock. This project aims at developing carbon negative concrete paver blocks by using M30 concrete mix incorporating optimum percentage of ferrock. The purpose of the project is to look into the durability and mechanical properties of prepared paver blocks. The optimum percentage of ferrock in the mix was 9%, and several tests were performed on paver blocks to determine compressive strength, tensile splitting strength, flexural strength, water absorption and abrasion resistance. All the tests’ results demonstrated significant improvement in strength when compared to conventional concrete paver block. The water absorption was also found to decrease while replacing cement with ferrock. These findings emphasize the potential of ferrock to be used as a sustainable replacement for cement in paver block.
