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 CO 2 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. Keywords: Ferrock, Oxalic acid, Mechanical Properties, CO2 absorption. 1. Introduction
Concrete is the most utilized structural ingredient in all places. Roughly 1 ton of cement is created every year from each person on the planet. In view of the broad use, it is critical to assess the effects of this material in the environment precisely. These days, a material's ecological effect is assessed with its individual impact on ozone harming gas discharges and environmental change. From this perspective, the Green concrete ide was evolved. Globally, cement production is in charge of 5 to 7 percent of carbon dioxide generated. David Stone is the author of another concreting innovation called Ferrock, in view of iron carbonate and utilizing to a great extent reused materials to deliver around 95%. It's giving promising suggestions as a choice to concrete and a far greener construction material. Being environment friendly, Ferrock uses all the materials from scratch viz., waste metal powder, Limestone, Metakaolin and Flyash. This concreting technology is far greener, stronger and durable compared to its predecessor.

2. Literature Review V Rajesh M Patel, Hardik J Solanki on “Development of Carbon Negative Concrete by using Ferrock”, IJSRSET (2018). In their experiment they partially replaced cement with Ferrock in gradually varying proportions from 20%30%. Specimens were cast and test for Compression, Tension and Flexure. The test results showed that 25.43% replacement gave optimal performance in compression, 17.51% in tension and 25.11% in flexure. Alejandro Lanuza Garcia et al on “FERROCK: A life cycle comparison to ordinary portland cement”, ISE 576 Industrial Ecology (April 24 - 2017). This is the only available published journal for proportioning of Ferrock. In this paper, Life Cycle Analysis (LCA) is utilized to look at the natural effects of Ferrock and Ordinary Portland Cement, concentrating explicitly on their commitment to carbon contamination, water usage. This procedure incorporates a top to bottom natural evaluation of Ferrock generation, from the purpose of its materials extraction to all its steps. The outcomes have been contrasted with a past life-cycle investigation of OPC. This examination finds that Ferrock has both the possibility to supplant OPC, and contribute essentially to the advancement of an feasible future. Balraj More, Pradeep Jadhav, Vicky Jadhav, Giridhar Narule, Shahid Mulani in their research paper “CO2 Absorbing Concrete Block”, IJTEEER (Volume 2, Issue – 7, ISSN 2347 – 4289). In this paper they founded the amount of CO2 absorbed by the concrete using the Zeolite powder and Zeolite sand as a supplementary material. They found that the Zeolite Concrete absorbs around 1 mole of CO2 from atmosphere in 50 days. 3. Materials and Properties Ferrock is used as a binder material. Ferrock is a blend of various materials like Iron Powder, Fly Ash, Limestone, Metakaolin and Oxalic acid. Ferrock has a specific gravity of 5.29 of size 90 microns. Locally available M-Sand (passing through 2.36 mm) with Fineness modulus 4.66 having Specific gravity 2.73 were used based on IS 383 (2002). Potable tap water was used for mixing and curing of concrete.
