Mechanical and Durability Properties of Fly Ash-Based Geopolymer Concrete
Portland cement plays a very important part in construction, but the manufacturing process emits almost 5–7% of the CO2 in the world and it is one of the main causes of global warming. This paper discusses about the alternative material to Portland cement and compares between their strength and durability. The main material in this study is fly ash which is an industrial waste and easily available. In India, every year almost 120 million tons of fly ash is produced in the power plants and fly ash is very rich in silicon and aluminium; that is why it is a very good replacement for cement and this way we can recycle the waste also. Geopolymer is a mixture of fly ash with sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). In this paper, geopolymer is made using the combination of M25-grade concrete. The ratio between NaOH and Na2SiO3 is kept constant which is 1:2 and the morality of NaOH varied from 10 M to 16 M. In geopolymer concrete, cement is 100% replaced by fly ash. The compressive strength and durability parameter is compared between geopolymer concrete cubes (which is kept at different curing conditions) and concrete cubes in which Portland cement is replaced by 25% of fly ash.
