Effect of Steel Industry Waste as a Cement Replacement to Produce Sustainable Concrete Considering Strength and Durability
Publication: Urbanization Challenges in Emerging Economies: Resilience and Sustainability of Infrastructure
ABSTRACT
The present investigation is dealing with the influence of steel making industry waste as a cement replacement, which will directly reduce the CO2 emission in environment due to use in concrete considering the long term durability and sustainability of structure. The study has been carried out by comparing and implementing the waste material for the research by rigorous literature survey. The oxide compositions (viz., Al2O3, SiO2, CaO, Fe2O3) of the waste material is investigated and compared with the cement to use as a cement replacement. The behavior of concrete containing waste was checked out at different percentage replacement (10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90%). For the accurate results, chemical parameter were investigated for the waste material and all fresh as well harden properties were find out to check feasibility of waste as a cement replacement in concrete. To understand the performance of concrete, all these parameters were checked after salt exposure, hydrochloric acid exposure, and magnesium-sulphate exposure till 28 days, 56 days, 90 days, 120 days, 150 days, and 180 days. These specimens were kept under 40°, 60°, 80°, and 100° degree temperature to observe the performance of concrete, if this will be used in hot climate country. The concrete produced from waste replacement was compared with the conventional concrete, and all fresh properties, compressive strength, flexural strength, split tensile strength, and durability were investigated by taking different trials adjusting different w/c ratio and admixture dosages. The investigation was completed for 6 months for different parameter as per the guidelines given in specifications to maintain the accuracy in methodology and improved results were found for particular mix design with optimum cement replacement. This investigation gives the option of cement which will directly benefit to reduce CO2 emission as well in cost reduction of concrete which gives the sustainable and economic solution for the structure.
