Aggregate and Local Characteristics of Vibrated (V), Centrifuged (CF), and Vibro-Centrifuged (VCF) Concretes
This chapter presents the original test method for researching the functionally gradient cross-sections of vibrated, centrifuged, and vibro-centrifuged concretes in order to determine their aggregate (general) and local (differing in layers) strength and strain properties with deformation diagrams. It is proved that by using vibro-centrifugation it becomes possible to obtain concretes with improved structure and higher characteristics compared with centrifugation and vibration procedures. A three-layer model of the functionally gradient structure of centrifuged and vibro-centrifuged concrete has been experimentally confirmed. Differentiation of the characteristics of layers of functionally gradient concrete is obtained: the concrete of the outer layers has the highest strength, modulus of elasticity, and the least deformability; the concrete of the inner layers demonstrates the lowest strength, modulus of elasticity, and the highest deformability; the concrete of the middle layers shows average characteristics. The corresponding deformation diagrams are also differentiated by layers.
