Abstract
Concrete is relatively brittle, and its tensile strength is typically only about one tenths of its compressive strength. Conventional concrete is therefore normally reinforced with steel reinforcing bars. Steel reinforced concrete normally suffer from corrosion of the steel by the salt, which results in the failure of those structures, and decrease the life of the structure. Electromagnetic interference is an undesirable and uncontrolled off-shoot of explosive growth of electronics and widespread use of transient power sources. EMI makes the environment increasingly be exposed to the electromagnetic pollution. People who have been exposed to a high electromagnetic environment for a long duration become more susceptible to leukemia and brain tumors. Carbon, Mu-metal, metal filling materials. In order to overcome these problems, Stainless Steel fiber can be adopted. The Stainless Steel fiber acts similar to that of steel fiber but it will not be subjected to corrosion. The paper deals with the effects of addition of various percentage of stainless steel fiber (0-1.5%) in addition with M30 grade of concrete. An experimental program was carried out to explore its effects on compressive, tensile, flexural strength, EMI shielding behavior. The optimum strength is found and beam is casted and then the strength is calculated. The experimental strength of beam is compared with ANSYS result and graph is drawn. A notable increase in flexural, tensile and compressive strength was found.
