Effect of Disperse Reinforcement on the Structural Quality Factor of Vibrated and Centrifuged Concretes on the Сombined Aggregate

Abstract:

The article considers and evaluates the impact of dispersed reinforcement of vibrated and centrifuged concretes manufactured with various types of fibers on their strength-density ratio. The authors considered the application of such a recipe manufacturing method as combining aggregates by the example of heavyweight aggregate - crushed stone and light aggregate - expanded clay aggregate for these concretes. Registered strength-density ratio of centrifuged fibrous concretes with a combined aggregate is higher than vibrated concretes with the same composition of the studied fibers. The highest growth of the strength-density ratio for the centrifuged fibrous concretes as compared with the vibrated ones was identified in case of dispersed reinforcement with steel fiber.
