Experimental Study on the Hardened Properties of Concrete by Using Soft Drink Bottle Caps as Partial Replacement for Coarse Aggregates

Cement concrete is the most extensively used construction material in the world because of its great workability and can be moulded to any shape. Ordinary cement concrete possesses a very low tensile strength, limited ductility and little resistance to cracking because of the presence of internal micro cracks, which leads to failure of the concrete. In this modern age, civil engineering constructions have their own structural and durability requirements, depending upon its purpose and for this, modification in traditional cement concrete is must. Addition of different types of fibers to concrete in specific percentage improves the mechanical properties, durability and serviceability of the structure. It is learnt that Steel Fiber Reinforced Concrete (SFRC) has its superior resistance to cracking and crack propagation. Hence an attempt is made to study the influence of cut bottle caps as a steel fiber concrete as partial replacement for coarse aggregates and studying the parameters like compressive strength, split-tensile and flexural strength of conventional and steel fiber reinforced concrete Therefore it can be seen that compressive, split-tensile and flexural strength of fiber reinforced concrete has been increased as compared to conventional concrete by replacing coarse aggregates with bottle caps.

Key Words: Bottle Caps, Steel fibers, fiber reinforced concrete, compressive, split-tensile and flexural strength.
