Over time, the mixture solidifies into a durable substance. It is used in a variety of building projects because of its affordability, toughness, and capacity to take on nearly any shape. Concrete is the artificial material that is used the most in the world. To explore the properties of concrete, it is suggested that some of the coarse aggregate needed to provide the necessary strength be substituted with coconut shell. It could be advantageous to replace some of the coarse aggregate with coconut shell at percentages of 5%, 10%, and 15%.Fibres possess the properties that increase the durability of concrete. Among them is carbon fibre. These carbon fibres offer superior mechanical properties and could be used more effectively. By examining differences in fibre composition, this study aims to compare the strength of carbon fibre concrete with regular concrete. Concrete containing carbon fibre is tested at 0.5%, 1%, and 1.5% of the total volume of the concrete. The concrete's split tensile strength and compressive strength were evaluated for 28,56 and 90 days.
Because of its low density, great heat conductivity, superior chemical stability, and remarkable abrasion resistance, carbon fibres can be used to reduce shrinkage and breakage. The structure's tensile and compressive strengths are enhanced by these fibres. Carbon fibres also increase durability and dry shrinkage. Conversely, carbon fibres lessen electrical resistance. 2. OBJECTIVES: 1. To enhance the coarse aggregate with a partial coconut shell substitution. 2. Examining the mechanical properties of carbon fibre reinforced concrete is the primary goal of this study. 3. MATERIALS 3.1 Cement: A binder, often known as a material that hardens, solidifies, and unites other materials to form a bond, is what cement is. Typically, sand and gravel are mixed with cement to create a mixture. Concrete is made by combining cement with sand and gravel, while mortar is made by mixing cement with small particles. In building, cement is utilised; it is typically inorganic, frequently derived from calcium and lime silicate, and available in both hydraulic and non-hydraulic forms.
KEYWORDS: Coconut shell, Carbon fibres , Compressive strength and Split tensile strength. I. INTRODUCTION Concrete is a composite material that dries over time and is made of cement paste and fine and coarse aggregate. The majority of the concert is made of hydraulic cement or concrete with a lime base. Waste products like peanut shell ash are produced by the peanut industry. Usually, it is disposed of outside without considering the advantages for the economy or the environment.
3.2 Fine Aggregate: In the current experiment, the fine aggregate was river sand that was easily accessible. 3.3 Coarse Aggregate: Aggregate that remains above the IS Sieve 4.75 mm is referred to as coarse aggregate. An incremental size increase of 10–20 mm is the typical maximum, according to IS383:1970.
The coconut shell is another material that can be used in place of other elements in concrete. A portion of the coarse material in this project is replaced with coconut shells. As a result, there are fewer land filings related to waste material dumps in barren areas. The impact load resistance of coconut shells is significantly higher than that of ordinary concrete.
