Investigation on Ferrock Based Mortar an Environment Friendly Concrete

Abstract

Concrete is the most used building material for Construction works, which is responsible for 70% of the industrial carbon dioxide emission. From this perspective, the green concrete concept has evolved and more researches have been done on replacement by green materials. Ferrock is a binder that is a blend of Iron Powder, Flyash, 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 varying the oxalic acid (Catalyst) concentrations among the constituents of the Ferrock mortar mix. From results, it has been found that the optimum molarity of oxalic acid as catalyst was 10 moles and ferrock also absorbs considerable amount of CO2 from the atmosphere and reduces the amount of CO2 emitted from the industries.
