The article considers and evaluates the impact of dispersed reinforcement of heavy concretes manufactured by means of vibration and centrifugation, various types of fibers on their strength-density ratio. The options of applying different types of heavy-weight aggregates for these concretes: crushed stone, limestone and sandstone are considered. The highest strength-density ratio is registered in centrifuged crushed stone fibrous concretes, and all types of centrifuged concretes has the ratio higher than vibrated concretes with the same composition of the studied fibers. The highest growth of the strength-density ratio for the centrifuged crushed stone fibrous concretes as compared with the vibrated ones was identified in case of dispersed reinforcement with steel fiber. |
