Methods of research - planned experiment, statistical analysis, physical and mechanical tests. Technological conditions for obtaining high-strength concretes and fiber-reinforced concrete from rigid and super-rigid mixtures, which are compacted by vibrocompression, have been developed. The possibility of obtaining high-strength heat-resistant ash-and-slag concretes and basalt-fiber-reinforced concrete with the temperature of possible use in 800 ° C has been determined. A set of studies to determine the effectiveness of increasing the dynamic stability of concrete due to damping inclusions and layers in concrete in the form of dispersed components. The proposed methodology for designing compositions of concrete and fiber-reinforced concrete that was investigated in the work with a complex of standardized indices of their properties. Methodological bases of constructive calculations of reinforced concrete fortifications with allowance for the characteristics of firearms, the possibility of using damper (spring) systems are developed. The results of full-scale tests of reinforced concrete structures with the use of high-strength fine-grained fibrous concrete and a damper layer from a mineral wool board, which are tested at a military training ground, are presented. The field of application of the results is the construction industry, reinforced concrete structures for defense purposes under conditions of powerful weapons Product Description popup.authors Бабич Євгеній Михайлович Бордюженко Олег Михайлович Дворкін Леонід Йосипович Житковський Вадим Володимирович Ковалик Ірина Володимирівна Ковальчук Тарас Володимирович Кочкарьов Дмитро Вікторович Скрипник Микола Михайлович Степасюк Юрій Олександрович Філіпчук Сергій Вікторович popup.nrat_date 2020-04-02 Close
