Experimental Study on Properties of Steel Fiber Reinforced Concrete

Abstract

Concrete is derived from Latin word “concretus”. It is the second most used material after water. The use of concrete in construction has been increased many times in last few decades. Along with its advantages like high compressive strength, fire resistance, high water resistance, low maintenance and long service life, concrete also has many disadvantages for e.g. rebar corrosion, aggregate expansion, freezing of trapped water, moisture ingress, leaching, spalling etc. Such problems can decrease the durability of concrete and can increase the overall construction cost of the structure. This created the need of development of a new type of concrete, which is superior to the conventional concrete. Such concrete is known as steel fiber reinforced concrete which reduces the permeability of concrete, thus reduces the chances of moisture ingress. Such concrete also impact resistance, ductility, flexural strength etc. This examination incorporates the experimental investigation of properties of cement and steel fiber reinforced concrete and after that contrast these with properties of conventional concrete All the experiments included in this project have been performed at (17 ± 2)o C and satisfy all the specifications given by Indian Standard Codes.
