ABSTRACT

In this paper, the overall review about the change in strength parameters and ductility behaviour of reinforced concrete beams is discussed when reinforced concrete beams are strengthened with self-compacting concrete jacketing. The purpose of self-compacting concrete jacketing is to increase the strength of existing structural members to strengthen the damaged structural members or due to increase in service load on structural members.  Various reasons causing damage to structural members are design errors, faulty construction, earthquakes, accidents, fire etc. Self-compacting concrete jacketing is used for repair and rehabilitation of damaged structural members. The discussion includes effectiveness of self-compacting concrete as jacketing material for overall enhancement of structural members.
