Deformability and features of destruction of centrifuged concrete during shock loads

A literature review on the behavior of materials in products and structures operated under repeated mechanical loads was conducted. Impact is considered as a type of mechanical loads on the concrete. Factors affecting the resistance of concrete to impact were studied. The operation features of various engineering structures, specific substructures subject to random or regular shock loads, such as hydraulic engineering and transport structures, were determined. A set of experimental laboratory studies was carried out. The factor of concrete coarse aggregate type was investigated. Options of using granite, limestone, and sandstone as a filler of spun concrete were studied. The results are processed and analyzed. The influence of prescription and process factors on the deformability and fracture characteristics of spun concrete under impact loads is estimated.A literature review on the behavior of materials in products and structures operated under repeated mechanical loads was conducted.
