  • Abstract:
  • Concrete is the most used building material for Construction works, which is responsible for 70% of the industrial carbon dioxide emission. Cement is a major binding component in concrete. It is of great importance in construction industry. Even though cement has these prominent properties, it emits carbon dioxide. From this perspective, the green concrete concept has evolved, and more research have been done on replacement by green materials. Ferrock is an innovative iron-based binding compound, which presents a carbon-negative alternative to cement that utilizes a variety of waste streams to produce a versatile building material Ferrock is a binder that is a blend of iron Powder, fly ash, lime Powder, metakaolin and oxalic acid. Oxalic acid acts as a catalyst and on reaction with CO2 and water produces Iron Carbonates, which is the hardened product. It can enhance the environment by absorbing the atmospheric CO2 for its hardening process. The current work was carried out by replacing the cement with 10%, 20%, 30%, 40%, 50% and 100% of ferrock in the cement mortar cubes. From results, it was found that the optimum percentage of ferrock was 30%. Then mix design for M30 grade concrete was prepared and cubes of size 15cm X 15cm X 15cm, split tensile cylinders of size 15cm diameter X 30cm height and flexural beams of size 50cm X 10cm X 10cm for both conventional concrete and ferrock cement concrete with 30% replacement of ferrock were casted. The specimens were kept in water curing for 7, 14 and 28 days and in CO2 curing for 7 and 14 days. After the curing period the specimens were tested for compressive strength, split tensile strength, flexural strength, carbonation, and carbon dioxide absorption. Then the results obtained were compared with each other.
