Abstract: When NASA builds on the moon and in space, the structures will be concrete, say researchers at the Portland Cement Association's Construction Technology Laboratories. They foresee producing concrete on the moon from local materials. On earth, silica fume additives are proving to be more valuable for durability, impermeability and resistance to chemicals than for high strength per se. Silica fume concrete was chosen for these qualities as the exterior wall of Global Marine Development Co.'s CIDS offshore drilling platform, located in the Bering Sea. Roller compacted concrete, suddenly popular for constructing gravity dams, is being used for heavy duty pavement in the U.S. First civilian example is Burlington Northern Railroad's intermodal hub facility in Houston.
