An Experimental Study on Banana Fibre Reinforced GGBS Concrete

Abstract

Fibres have been used to reinforce concrete over the last few decades because fibre has significant influence on concrete’s static and dynamic properties.Fibre reinforcement into concrete can provide a timely, workableand inexpensiveprocedure for reducingcracking and similar type of deficiencies.Industrial wastes like fly ash,Ground Granulated Blast Furnace Slag (GGBS) etc.,can be utilized as substitution of cement. At the same time, the usage of GGBS as partial substitution of cement will lower the concreterate and helps to decrease cement consumption rate. This paper describes the experimental function on the usage of banana fibre and Ground Granulated Blast Furnace Slag (GGBS) to make better strength and applications of concrete. Banana fibres are extensivelyobtainableeven as agricultural scrap from Banana cultivation. Theyhavekey characteristics like low density, light weight, cheap, high tensile strength, water andfire resistant. They are eco-friendly,inexpensive (zero cost)with chemicals free. The adding of bananafibres considerably improved many attributes of the concrete such as compressive strength, tensile strength and flexural strength. It also increased the potential to withstandrupturing and collapsing of concrete.In this study,banana fibres of four different percentage (0%, 2.5%, 5%, and 7.5%) having length of 40mm and constant percentage of GGBS (2.5%) were used. The banana fibre reinforced GGBS concrete were tested for compressive strength,tensile strength at different ages.
