Replacement of Fine Aggregate by Iron Ore Tailing (IOT) in Concrete for Sustainable Development Geena George E3s Web of Conferences, 2023 An increase in iron ore processing to meet the global demand has resulted in the generation of billions of tons of iron ore tailings (IOT). Also, the increase in construction activities has led to the over exploitation of river beds for sand. In this present study, fine aggregates are replaced by iron ore tailings in M20 grade concrete at varying percentages of 20%,30%,40%,50%,60%. The cubes and cylinders were casted and their compressive strength and split tensile strength were evaluated for 7 days and 28 days. It is observed from the test results that the iron ore tailings aggregate concrete exhibited a good mechanical strength compared to the control mix. The compressive strength has increased with the increase in replacement of iron ore tailings in concrete, which has shown an improvement of 18.41% over conventional aggregate concrete. An incremental increase of 10.3 % was observed in the case of split tensile strength for 60 % replacement of fine aggregate with iron ore tailings.
Study on characteristic strength of Geopolymer Aggregate Concrete Geena George, K Asha Iop Conference Series Earth and Environmental Science, 2022 The stone quarrying activities to meet the demand for infrastructure development, which in turn impacts on the soil and water resources, affect the hydro-geological and hydrological regimes. Due to the increase in urbanisation and industrialization, a large quantity of industrial waste is produced in developing as well as developed countries, and the unscientific disposal of this industrial waste is creating huge environmental problems. In this study, an attempt is made to incorporate both the problems and to find an alternative for natural aggregates with industrial by-products fly ash and GGBS for manufacturing artificial aggregates by adopting the geo-polymerization technique. The characteristic strength, flexural strength, and split tensile strength of geopolymer aggregate (GPA) concrete for varying percentage replacements, such as 25%, 50%, 75%, and 100% for natural coarse aggregates, have been studied and compared with normal concrete. Based on the test results, geopolymer aggregates could be considered as an alternate source for natural aggregates. The 28-day compressive test results showed that for 75% and 100% replacement, GPA3 concrete has been conducted with XRD analysis and SEM analysis on the microstructure of geopolymer aggregates manufactured with varying mix ratios of source materials and curing periods of X-Ray diffractograms and patterns. exhibit the formation of N-A-S-H and C-A-S-H compounds, which indicates the geopolymer formed has similar chemical compositions as natural rocks.
