Repair and Rehabilitation of Buildings

UNIT 1: Deterioration of concrete in structures: physical processes of deterioration like F & T abrasion erosion pitting chemical processes like carbonation chloride ingress corrosion alkali aggregate reaction sulphate attack; their causes mechanism effect preventive measures. UNIT 2: N.D.T.: Non destructive test methods for concrete including rebound hammer ultrasonic pulse velocity rebar locator corrosion meter penetration resistance and pull out test core cutting etc. UNIT 3: Materials for repair: polymers and resins self curing compound FRP Ferrocement etc; properties selection criterion bonding aspect.UNIT 4: Repair Techniques: grouting jacketing shotcrete externally bonded plates and under water repair; materials equipments precautions process etc.UNIT 5: Allied topics such as Structural Health Monitoring and Investigation for structures: Distress observation and preliminary test methods.
