"Concrete and reinforced concrete remain the main building materials for construction of modern fortifications. Development of modern technology for concrete and fibre reinforced concrete structures opens new opportunities for a significant increase in the protective capacity of reinforced concrete structures for defense purposes under the influence of powerful weapons. The book presents experimental and theoretical results allowing production of special high-strength rapid hardening concrete and fiber reinforced concrete. It describes a method for effective proportioning of high-strength fast-setting concrete and fiber reinforced concrete with high dynamic strength as well as selecting proper technological parameters, methodology for design of reinforced concrete structures using such concrete. Particular attention is paid to ensuring the early strength of concrete at 12 - 24 hours after casting, possibility to construct structures considering limited availability of energy resources at the site"--
