Construction with Field Moldable Polyurethane Foam Blocks.

摘要

This report presents the results of an investigation of the use of polyurethane foam for expedient shelters in the theater of operations (TO). The evaluation showed that polyurethane foam can bring about significant savings in material shipping weight and volume, construction time, and required personnel skill levels, compared to present base development materials. A model structure was erected in which the wall components were building blocks molded from a low density foam. The building blocks can be fabricated in the field by low-skill personnel using simple molds and mixing equipment. The blocks are equal in size to two regular 8 by 8 by 16 in. (203 by 203 x 406 mm) concrete blocks and weigh about 4 lb (1.8 kg) each. They can be rapidly assembled into a wall using an adhesive applied by caulking gun. Conventional foundation, floor, and roofing systems can be used with this wall system. (Author)
