Study Of Non Destructive Test On Concrete

Abstract

In The Recent Past, Non Destructive Techniques To Evaluate Defects And Strength Of Concrete Have Developed Great Importance. These Techniques Have Their Own Advantages As Well As Limitations, When Compared To Conventional Strength Estimation And Damage Detection Tests. In This Project Various Concrete Specimens (Beams And Square Slab) Were Cast And Discontinuities Were Created In These Using Thick Paper Sheet And Wooden Pieces At Varying Depths And Position Within The Specimens. The Objective Of This Project Was To Detect These Defects By Using Three Techniques: (1) Rebound Hammer Test (2) Ultra Sonic Pulse Velocity Test (3) Thermal Imaging Technique And Finding The Most Suitable And Economical Technique To Serve The Purpose. Use Of Thermal Imaging Technique In This Area Is A Very New Concept And Its Relevance In This Area Has Been Explored In This Project And It Has Been Found That This Technique Is Of Great Use In Detecting Defects In Concrete. Please Note That This Project Does Not Deal With Determining The Strength Of Specimens.
