In basic terms, you can not.
you can strengthen a reinforced concrete beam by application of a steel plate/frp up to a point where the area in the stress block under compression is at a max. allowable limit as stated in the code you are using. At this stage, the concrete is close to a crushing instantaneous failure and the beam can not be strengthened further.
