Paper Details

The main activity of the mining industry is the sawing and polishing process of rock blocks. This activityproduces a large amount of mud consisting essentially of SiO2, Al2O3, Fe2O3, and CaO. This is estimated at 32-40 cubicmeters/day [1]. After the stone was air-dried, it became a very good material that was easily inhaled by humans andanimals. It was thought to cause severe lung disease in the local people and could cause serious damage to theenvironment, such as soil and groundwater contamination, if not effectively treated before treatment. It has been shownthat utilization of waste materials which are rich in aluminosilicate content can be used in geopolymer concrete.Through geopolymerisation waste materials can be transformed in building material with excellent mechanical anddurable properties like acid resistance and fire resistance. In this research work, polymerization of Granite waste inreplacement of fly ash (Class F) with different alkali-activators based on combinations of Na2SiO3 and NaOH has beeninvestigated. The geopolymer concrete was prepared with varying doses of granite waste dust in replacement of fly ashlike 10%, 30%, 50%, 70%, 100%. The geopolymer concrete is prepared with 0.5 alkaline solutions to fly ash ratio. Thecompressive strength of 16-65 MPa was obtained in different replacement of granite dust in geopolymer concrete. Theperformance of these geopolymer concretes in aggressive environments has also been studied using tests for acidresistance and Rapid chloride penetration test. Compared with ordinary concrete, all geopolymer concretes exhibitexcellent acid corrosion resistance (5% of H2SO4+HCL).
