Effect of Cotton and Flyash on Concrete

Aim of this study to determine Compressive strength, Flexural strength and Split Tensile strength of M40 grade concrete with use of cotton and fly ash. SIKAPLAST 5223 NS is used to improve the workability of concrete which is a unique multipurpose super plasticizer that is particularly suitable for the production of ready mixed concrete. Additionally, it provides high water reduction and improved fresh concrete characteristics. Fly ash can be utilized to produce high strength and durable concrete composites. The Concrete specimens were cured on normal tank curing under normal atmospheric temperature. The strength determined at 7, 14 and 28 days, Flexural, Compressive and Split Tensile. The addition of Cotton by the weight of concrete shows an increase strength property and fly ash as cement replacement material shows early long-term strength. This system that is Ordinary Portland Cement – Cotton – fly ash concrete was found to increase the Compressive, Flexural strength and Split Tensile strength of concrete on all ages when compared to concrete made with Cotton and fly ash.
