Structural Health Monitoring of Concrete Structure by Non Distructive Evaluation

Abstract

Day to day we see various defects and problems in our structures like cracks ,honeycombing, settlement and displacement, deformation and so on which is directly responsible for the lifespan of structure. But we really aware of about our structure conditions? We really need to monitor the health of our structures? Anyone curious about what exactly causes of these defects? Yes! Structural health monitoring is very necessary and essential in these days. In these polluted world ,various causes are responcible for structural deteriotions. Structural health monitoring ensure the quality and structure life span. Structural health monitoring is nothing but monitor or investigate the change occurs in the structure which help the understand compressive strength of material. Then how to monitor structure ? Yes it is possible without distruction of building, which is using non distructive testing evaluation. in civil engineering various NDT has like rebar hammer, ultrasonic velocity ,carbonation test and half cell potentionmeter
