Previous studies indicated that lightweight sulfur foams had thermal insulating characteristics and mechanical properties which were sufficiently attractive that they could be considered for a number of structural applications. The subject study was undertaken in order to determine if the process for preparing sulfur foam could be scaled up from small laboratory-size equipment, producing 4 lb of foam per batch, to large conventional pressure-heated equipment capable of producing 500 lb of foam per batch. This was accomplished, and large quantities of sulfur foam were prepared and tested for such applications as subbases for roadways, as foam core panels, and for foamed-in-place structures. The sulfur foams appear particularly attractive for the subbase applications and foam core panels. Further investigations are required for the foamed-in-place structures because of the initial creep characteristics associated with the sulfur foams, first identified during the course of this study.
