摘要：	Experiments were conducted to determine the mechanism of concrete "scaling" or deterioration on airfield parking aprons used by F/A-18 Navy jets. Some of the "scaling" was caused by heat from the auxiliary power unit (APU) and some was caused by phosphoric acid attack on the heated concrete. The phosphoric acid originated from hydrolysis of organic phosphates in used engine oil. The mechanism was confirmed by demonstrating that the concrete scale debris was high in phosphate content.
