This report addresses a comprehensive laboratory investigation on the application of foaming mud cement (FMC) in the construction of containment barriers. FMC is a proprietary family of cellular concrete mixes. Information was gathered through an extensive literature search on existing containment barrier construction methods and grout mixtures. Over 140 FMC mix designs were established incorporating different types and amounts of cement, fly ash, coarse and fine aggregate, reagents, and foams. Extensive laboratory testing was conducted to determine physical properties of FMC such as unconfined compressive strength, shear strength, flexural strength, permeability, and unit weight. Scale model construction was conducted on numerous containment barrier designs utilizing FMC. These scale models progressed from bench scale (1/10), to 1/4 scale, 1/2 scale, and full scale (8 by 20 ft). Photographic documentation of this construction is included. Laboratory and scale model construction data were evaluated to determine the technical merit and cost effectiveness of each construction sequence. Conceptual site deomonstration program designs were established for both conventionally constructed and remotely constructed containment barriers.
