Abstract:
For the construction of reinforced-concrete ships it was desirable to develop a concrete of minimum weigth and maximum strength. This was accomplished by the use of a special fine ground portland cement and an aggregate which has been described in the technical press as "an artifically burned clay or shale uniformly filled with small non-connecting cells." This concrete weighed about 115 lb. per cu. Ft.; the mixture being one part cement, two-thirds part fine aggregate, and one and one-third parts coarse aggregate.
