Effect of Dimensional Variation of Test Section on Performance of Portable Ultrasound Non-Destructive Digital Indicator Tester in Assessment of Status of Concrete
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 6
Abstract
Aging of concrete structures and their interactions with persistent prevailing environmental conditions will alter its material properties and cause deteriorations. Inspite of maintaining the best quality control concrete may not behave as a homogeneous medium. Conducting any test in the modest way is the key factor for true assessment of the status of substratum. Diagnosis of the residual strength of concrete in insitu condition using non-destructive tests provides useful information for adopting suitable preventive measures. Deteriorations in the concrete can be broadly imaged using ultrasonic pulse velocity technique. However, the results of ultrasonic pulse velocity depend on various factors. To establish the effect of span length of test sections 16 tests were conducted at 4 different locations in the galleries of a hydroelectric project situated in the Himalayan region. This paper presents the findings of these tests which clearly emphasize the need of defining optimum length of test span for the best reflection of status of scanned area.
