EFFECT OF FIBRES ON STRENGTH CHARACTERISTICS OF CONCRETE

Abstract

Concrete is the mostly consumed material in the field of construction across the world. It can be easily moulded into any shape by the mixture of different materials such as cement, water, fine and coarse aggregate. In general, concrete can withstand against compression than tension. Hence to improve the tensile characteristics of concrete, different types of fibers can be incorporated to overcome strength and durability properties. Usually, fibers used in concrete are natural and artificial fibers. Among them synthetic and steel fibers are used in the present study. These two types of fibers are added in percentages of 0.5%, 1% and 1.5 % respectively by cement weight. The experimental investigation is carried out to utilize the synthetic and steel fibers in M25 grade concrete for the development of strength characteristics in terms of compression and are compared by performing destructive and non-destructive tests at curing and non-curing conditions. The optimum percentages of fibers content is determined and comparison is made between the results obtained. The results obtained are found to be satisfying the requirements.
