Description
This report presents recommendations for structural design, materials, and construction of structures commonly used for hazardous materials containment, including reinforced concrete tanks, sumps, and other structures that require dense, impermeable concrete with high resistance to chemical attack. The report discusses and describes design and spacing of joints, proportioning of concrete, placement, curing, and protection against chemicals. Information on liners, secondary containment systems, and leak-detection systems is also included.
Keywords:
chemical protection; liners; construction joint; containment systems; gas-tight; hazardous materials; joint sealant; liquid-tight; precast concrete; prestress; water-cementitious materials ratio; waterstop.
