Abstract: The Blast Pans of AIRFORCE STATION Awantipura is in a distressed condition and as a result the matter was referred to civil engineering department, N.I.T Srinagar. Inspection was done by a team of mechanical and civil engineers of the Institute. The Ultrasonic Pulse velocity test and Rebound Hammer Tests were used to check out the quality of concrete. However, the visual analysis was carried to locate the dampness, cracks and other defects in the buildings. The inspection was arranged and the structure was inspected and tested to find the extent of damage. With the passage of time, the RCC structures are showing signs of deterioration in the form of cracks, spalling and corrosion of rebars. The R.C.C. members have deteriorated which is making building unsafe for its use. If it is allowed to continue further, the structures will be completely deteriorate without serving its desired life period. So it is necessary to study the reasons to deterioration of RCC structures, by considering all the factors, which can cause deterioration. As per the conditions prevailed locally, the probable reasons for deterioration may be carbonation, chlorides, sulphates and corrosion. In present work, the strength of RCC components, effects of carbonation, chlorides, sulphates and corrosion levels of building are studied. The specific objectives of the study are to know: the effect of concrete cover, the effect of carbonation, the effect of chlorides and sulphates, corrosion levels in the structures, visual inspection, NDT tests to assess the quality of concrete structures and comparison of condition regarding safety and serviceability of RCC structures.
Keywords: Health Monitoring, RCC Structures, Deterioration and NDT Tests.
