JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives

To impart knowledge on different methods of mix design and also

methods of testing hardened concrete.

Course Outcomes

The learner will be able to correlate the results of destructive and non

destructive testing.

• 1. Concrete mix design by BIS, ACI and BS method-proportioning, batching, mixing, modeling of specimens for compression, modulus of elasticity and modulus of rupture-testing of specimens as per relevant codes of practice (Comparative study).
• 2. Development of correlation between Non-Destructive and Destructive tests using Rebound Hammer & UPV instruments.
• 3. Influence of following parameters on NDT reading-experimental observations.
• i. Aggregate Cement Ratio.
• ii. Water Cement Ration.
• iii. Excess/Deficient Cement.
• iv. Excess/Deficient Water.
• v. Aggregate type. (Some of the above parameters may be considered depending upon time)
• 4. Strain and deflection measurement for a structural member under single point/ two point loading- crack propagation observation. Measurement and plotting.
