A detailed engineering assessment of a 32-year-old 300 ft tall, brick-lined reinforced concrete chimney is presented. Tools used for the assessment include infrared photography, Schmidt hammer mapping, x-ray diffraction analysis, strength testing of concrete cylinders, and structural analysis by finite element and classical methods. Design and performance deficiencies are reported, as is the use of high alumina cement concrete not indicated on the engineering drawings. The chimney was found to be suitable for continued service after minor repairs.
