Because concrete is durable and relatively inexpensive, it is the most widely used construction material in industry and manufacturing. When used for chemical containment, however, concrete surfaces must be protected to prevent erosion and sealed to keep chemicals from entering the soil. There are two ways chemicals can deteriorate concrete: Direct chemical attack. Almost all inorganic chemicals, and many classes of organic chemicals, attach concrete. These attacks can be rapid, as with strong acids, or quite slow, as with milder chemicals; and Physical breakdown. When inorganic chemical solutions permeate concrete and crystallize, expansion occurs. This expansion physically breaks down the concrete. Under certain conditions, deterioration can be rapid. concrete structures commonly requiring protection from chemical attack include floors, ponds, pits, sumps, trenches and storage tank secondary containment areas. This paper discusses coatings to protect concrete from hazardous chemicals.
