Title: Reinforced Concrete Antenna Pedestal
Author(s): Benjamin P. Saldua, Ethan C. Dodge, Peter R. Kolf, and Carlton A. Olson
Publication: Concrete International
Appears on pages(s): 40-42
Keywords: defect, repair, roof, slab
Abstract:Nondestructive testing was used to evaluate concrete consolidation in an antenna pedestal recently constructed at the Canberra Deep Space Communications Complex in Australia. Evaluations were based on impulse-response tests, ultrasonic shear-wave tomography, core tests, and visual observations. The work showed that impulse-response testing allows rapid, reliable identification of significant defects. The consequent repair program is summarized.
