The consumption of raw materials not only depleted natural resources but also increases the toxic material in the environment by the construction industries. The substitute prod- ucts have been found to save the environment and natural resources up to some extent. In the same con- text, some usual composition of concrete mix is replaced by industrial/ natural wastes such as Fly Ash, Sugarcane bagasse ash and Banana fibre. The samples were prepared with the different composition using different % replacement of cement and sand. Therefore, concrete mix is developed using fly ash (re- placing 20% of cement) and partial replacing sand by an industrial waste i.e. Sugarcane bagasse ash (re- placing 0%,10%,20% of sand) with adding banana fiber (0%,2.5%,5%). Samples were evaluated and compared with standard concrete mix under characteristic compressive strength and flexural strength. It was observed that observed that addition of 2.5% of banana fibre in Cement; partially replaced by 20% of Fly Ash, and Sand; partially replaced by 10% of Bagasse Ash is the best Combination which gives better mechanical properties.

Introduction Concrete is a kind of composite material used in constructions of buildings. The concrete is formed by binding together fluid cement, water, sand and aggregates [1]. The most commonly used concrete is the Portland Cement Concrete. One of the main con- stituents of concrete is cement which is harming the environment at a very fast rate. Cement is a fine grey powdery substance which is made by burning a mixture of clay and lime, and sets hard when it is mixed with water. The manufacturing of cement involves several pro- cesses like crushing, milling and proportioning of lime, silica, alu- mina, iron and gypsum. Cement is a binder material which is a substance that helps in binding different materials together [2]. This property makes it an excellent constituent of concrete. Pro- duction of Cement generates high amount of CO 2 . Cement is the 3rd largest producer of man-made CO 2 in the world after transport sector and energy generation sector [3].It is estimated that about 0.97 tons of carbon dioxide is released to the environment for the production of 1 ton of cement. Carbon dioxide is one of the cat- egories of greenhouse gas and is largely responsible for global warming [4]. This prompts us to study the various alternatives to cement to make the concrete environment friendly. The usage of waste materials or by products from the manufacturing industries can be used as a partial replacement of cement in concrete without reducing the desired strength of the concrete. Fly Ash is one of the pozzolonic materials produced by burning the coal in thermal power plants. It is also known as pulverised fuel ash, hopper ash; chimney ash and constitutes about 80% of total ash generated in power plants. Instead of disposing this huge amount of fly ash in land, it can be effectively used as a replace- ment of cement in concrete. Many research and studies has stated that in concrete fly ash can be replaced about 50–60% of cement. This type of concrete is known as High Volume Fly Ash Concrete which produces mixtures that show high workability, high ulti- mate strength, and high durability. Utilization of fly ash in concrete minimizes the carbon dioxide emission problems to certain extent https://doi.org/10.1016/j.matpr.2020.06.006 2214-7853/Ó 2021 Elsevier Ltd. All rights reserved.
