In the selection of the insulating material to be used for coating the secondary containment dyke of a liquefied natural gas facility, three different types of insulating concrete made with various lightweight aggregates were investigated. These included resin-based concrete, latex- modified cement-based concrete, and cement-based concrete. It was found that cement-based insulating concrete with closed-cell polystyrene beads as the main aggregate is the most promising for cryogenic insulation.
