THE PROSPECTS FOR USING SAND CONCRETES FOR BUILDING REINFORCED CONCRETE SHIPS, ARMORED CEMENT SHIPS, AND ONE-PIECE INTERSECTIONAL JOINTS,
Abstract
The extensive research carried out on the physical and mechanical properties of types '300', '400', and '500' sand concrete mixed in plastic mixtures and with existing dockyard technology clearly demonstrates that sand concrete possesses the characteristics of shipbuilding concrete and constitutes a prospective construction material for armocement and reinforced-concrete ships and for monolithing intersectional hull joints in reinforced-concrete ships. Sand concrete changes its physical and mechanical properties depending on its curing age, as compared to the properties of the concrete at the age of 28 days, which are essential to consider in design and building reinforced-concrete and armocement ships. Only through proper curing of the concrete, particularly during the first 7-14 days, will a high-strength, durable sand concrete be obtained. (Author)
