摘要

As the building industry has developed, the increased production of cement has become a substantial source of carbon emissions encouraging global warming. The present study investigates, for the first time, the combined effect of reduced graphene oxide and ferrock in enhancing concrete strength and durability while promoting sustainability. Ferrock reacts with carbon dioxide to form iron carbonates, contributing to its superior binding properties. Five concrete mixes were prepared with 0.2% reduced graphene oxide and 5%, 10%, 15% and 20% ferrock as substitute of cement. The fresh properties of concrete evaluated using the slump cone test and compaction factor test, while the hardened property assessed through compressive strength test. Durability performance was examined through rapid chloride penetration, water penetration, total absorption, and initial surface absorption tests. The results were systematically compared and reported. The compressive strength improved by 58.36% at 90 days of curing by mix RG0.2F10. The results found reduction of chloride penetration, water penetration, total absorption and initial surface absorption reduced by 72.47%, 35.29%, 61.9% and 35.71% respectively. The results found optimum replacement ratio was 10% with 0.2% of reduce graphene oxide by mix RG0.2F10. The study demonstrates the potential of reduced graphene oxide and ferrock as sustainable cement substitutes, enhancing strength and durability while promoting waste recycling and reducing soil pollution leads towards sustainable development.
