Assessment of concrete quality in the columns and deck slab of Supercritical Turbo Generator

Assessment of concrete quality in the columns and deck slab of Supercritical Turbo Generator (TG) foundation of Unit 5 of 2×660 MW Supercritical Thermal Power Station, Chhabra, Rajasthan

Sponsor: M/s. Larsen & Tubro Ltd. – Power

Objectives Achieved:

Assessment of concrete quality and integrity in the TG columns and deck slab using Ultrasonic pulse velocity (UPV) test. Based on the in-situ testing and analysis of test results, areas/zones of poor quality of concrete are identified and suggested for quality and integrity improvement. This would enhance the quality and integrity of TG foundation and enhance the long term durability and service life of the structure.
