Seven materials that are currently being considered for use as backpacking around deeply buried protective structures and silos were investigated for the effects of particular phenomena which may be present or occur in the environments in which the materials may be used. Certain physical characteristics necessary for a better understanding of a material's behavior when used as a backpacking were also determined. The materials studied included three low-density concretes, two foamed plastics, foamed glass, and foamed sulfur. Each material was investigated for its strength-deformation characteristics and limitations, the effects of attack by groundwaters of different compositions, the effects of freezing and thawing, constrained consolidation, permeability, cyclic loading, constrained modulus of elasticity, brittleness, compatibility, and resistance to attack by fungi and bacteria.
