Abstract:
Concrete deterioration was observed in footings in one of the oldest oil refineries (1949) in the Arabian Gulf A field survey was carried out to record the degree of deterioration and the physical conditions in more than 1000 footings. Samples are cut from the footings to study their condition and determine the cause of deterioration. The impact of the refinery 's envi-ronment on the mechanical, physical, and chemical properties has been identijed, and recommendations for prolonging concrete life are given. Results show that exposed concrete not only degraded noticeably when compared with buried concrete, but also the correlation between these properties has changed It is found that the relationship between the voids ratio and compressive sfrength is insensitive to the degree of exposure. The opposite is true for the bulk density relation with strength. The relation-ships of other properties varied between these two. It was clear that high-performance concrete would be more suitable for use in such industrial facilities where durability plays a more dominant role in the design.
