Experimental Study on the Effect of Steel Fibres on the Physical Properties of the Concrete
Abstract
Concrete is made of cement, fine and coarse aggregates and is one of the most widely used materials in the world. Stone has also replaced older materials such as masonry and masonry. Its durability, robustness and ease of use are its main advantages. Concrete is very resistant to compression. The only drawback of concrete is its low tensile strength. Historically, steel has been used as the material of choice to increase the tensile strength of concrete. Therefore, steel, glass, polypropylene, asbestos, carbon, organics, etc., to increase its strength / mass. Many kinds of fiber materials are added.
In this investigation, steel fibers or strips was added in concrete to improve tensile strength, which are derived from automobile tyres. These iron fibers are thin and short and randomly distributed throughout the stone. One of the biggest environmental problems faced by cities around the world in our daily lives relates to worn tires. To solve this global problem, the wire rope of the bead wheel is added to the stone to make the stone better and reduce the waste to some extent. The purpose of this research is to examine the performance of M20 grade concrete at 0.5 w/c when the weight percent of steel strips or fibers is 0%, 1%, 2%, 3%, 4%, 5%. cement (25 mm long and 0.5mm diameter). After curing on the 7th, 14th and 28th days, the samples were prepared and tested. A significant improvement in the properties of concrete was observed with the addition of steel fiber. Maximum strength with 3% fiber addition, more fiber addition reduces strength. For this reason, it has been determined that the steel fiber quality is 3%.
