Mechanical properties of fly ash composites—A review

Composites are widely used as a lightweight material in automotive, aerospace, transportation, wind turbines, and leisure industry. Different reinforcement materials are used in composites of which fly ash attracts the researchers as an important reinforcement due to its enhanced mechanical properties such as low density, improved ultimate tensile strength, toughness, compressive strength, impact strength, hardness, and decrease in ductility. Fly ash composites are manufactured by stir casting, in situ deposition technique, hand lay-up technique, and compo casting technique.
