Overview of Concrete Deterioration Due to Sulphate Attack and Comparison of Its Requirements in International Codes

Abstract Any material or geometric property change that has an impact on structural performance is known as deterioration. Although this phenomenon gradual, if it not evaluated and fixed in a timely manner, will have severe the structure and, some historical occasions, may result collapse. Deterioration variety of causes mechanisms. Some are regarded external, such environment, which critical areas with tough climate conditions, Arab Gulf, where temperatures humidity high, another factor low quality materials poor craftsmanship. Depending type used environment created, several precaution approaches for degradation be adapted. Sulphate attack one most widespread deteriorating mechanisms; chemical damage can cracks, spalling, disintegration structure, diminishing its strength. This paper presents thorough investigation degrading agent, including causes, effects, international code provisions, well recent studies subject focus Gulf Countries. The outcomes study demonstrated phenomenon, various mechanisms, negative structures. Despite distribution sulphates existence chloride precautionary measures taken successfully limited their
