Abstract:
An intensive investigation was undertaken to determine steps necessary to extend the useful life of a 2-story reinforced concrete building constructed in 1960 until requirements for a new facility could be firmly established. The building is part of a solid rocket propellant manufacturing facility and houses equipment for grinding ammonium perchlorate (NH, CIO,). The investigation involved examination of the original concrete design data and testing of cores taken from the floor slab, floor beams, and walls. The tests included x-ray diffraction, microscopic analyses of the aggregates, pulse velocity tests, and standard compression tests. Photographic records of crack growth were also studied. [Author]
