Abstract:
In various embodiments, systems and methods are provided for constructing and testing of a barrier providing secondary containment for aboveground storage tanks. Concrete storage containers can be manufactured with primary steel tanks and spill containment formed using an airtight tank wrap. Concrete storage containers can be manufactured with a barrier providing secondary containment to meet or exceed most current codes and standards commonly required for the storage of petroleum, flammable, combustible and other hazardous liquids. Such storage containers can include one or more thermal barriers that provide enhanced resistance when subjected to liquid-pool/furnace fire tests. Additionally, a concrete exterior acts as a thermal mass reducing temperature variations. The concrete exterior further provides a non-corrosive, durable exterior having increased vehicle-impact and projectile-impact resistance. Due to the method of construction in some embodiments, concrete storage containers are provided which give thermal/vehicle impact/projectile resistance while also meeting expectations in weight and buoyancy criteria.
