Investigation on Durability of Study Fiber Reinforced Concrete

The significance of concrete durability cannot be undervalued. Durability of concrete is simply defined as its capability to resist enduring action and chemical attack, while maintaining the engineering properties for desired life time. The durability of concrete is dynamic with looks to a structure’s life span. In this investigation, study on durability of fiber reinforced concrete made with steel and glass fiber has compared for M30 grade of the concrete. The fractions of fiber are 0.5%, 1%, 1.5% and 2% by the volume of concrete. Durability of concrete as relatively measured by conducting laboratory tests such as acid attack test and rapid chloride permeability test. In acid attack test concrete specimens were immersed in acid for 28 days and 56 days. The compressive strength, loss of mass are compared for acid immersed specimen with water curing specimens. Rapid chloride permeability test was conducted at 28 days and 56 days for eight mix proportion. It can be concluded that which type of fiber reinforced concrete is suitable for durability. Also concluded that the optimal usage of fiber in concrete in context of durability.
