Acid deposition the problem of the decade, has been the concern of many scientists and researchers over the last few years. Studies, conducted to determine the causes and effects of acid deposition, showed that many aspects of the human and animal lives are being affected. Acid rain is leading to the death of many lakes, and green forests, as well as the deterioration of many portland cement concrete structures. This report examines the mechanism of acid rain, the chemistry of its formation, the processes by which it is transported from the atmosphere to the earth's surface, and its effects on portland cement concrete. An experimental laboratory test was conducted using ten specimens ( representing portland cement concrete) and sulfuric and nitric acid solutions ( representing acid rain). The results of the test showed that acid rain is leading to the deterioration of concrete, thus, designers should take it into consideration when designing their structures.
