Synopsis:

A structure consists of the load carrying members which transfer the superimposed load to the foundations below. Its proper function must be served during its life. But the deterioration starts with some passage of time in case of RC structures. Various factors are responsible for this i.e environmental factors, loads, fire, and earthquake and so on.  The concept of structure health monitoring and strengthening of structures is a major step towards well being of any structural system and its intended performance under various loads. Ferrocement have been widely used in various forms as structural element. In the present paper, feasibility of using ferrocement is assessed for strengthening of a deteriorated RC two way slab. Rebound hammer and ultrasonic pulse velocity tests were conduced to assess the degree of deterioration. Results were presented in the form of load-deflection response of the slabs along with crack pattern of the slab at various stage of loading. Results are found to be in well agreement with those obtained from analytical investigations.
