Structural and shielding costs for hardened facilities represent a substantial portion of the construction effort in both cost and time. Presently, the selection of a material is made a priori in favor of reinforced concrete and steel which places limitations on conceptual designs. Potential does exist for reducing construction time and cost of hardened facilities by using new material systems which have been successfully formulated to meet given functional and performance requirements. The material system investigated using analytical and experimental techniques consisted of a conventional portland cement concrete beam which had a layer of fibrous polyester concrete at the compression surface. The analytical results were used to determine the cost-performance feasibility of the reinforced concrete-fibrous polyester concrete material system. The performance analysis results indicate that the reinforced concrete-fibrous polyester concrete material system is performance effective when using ultimate strength design procedures and thus can be used to produce smaller and lighter weight structural elements that are more deployable than the conventional reinforced concrete structural elements.
