Impact of Technological Parameters of Vibration on the Integral Characteristics of Vibrocentrifugal Concrete

For the best compaction of the concrete mix, it is appropriate to use the method of centrifugation together with vibration. This mode is appropriately called vibrocentrifugal. In the process of vibrocentrifugation, vibration can also be considered as a method for diluting the concrete mixture at the stages of its dispersal under the influence of centrifugal forces. Under the proposed experimental setup to generate vibrocentrifugal items with variational structure and method of their production was allocated to the process parameters that have the most significant influence on the characteristics of vibrocentrifugal concrete and constructions. In the experiments, the following technological factors varied: the height and length of the technological projections of the clamps, the step between them, and the vibration mode. The problem of evaluating the influence of these factors on the integral (general, cross-section averaged) characteristics of concrete was investigated. The results of experimental studies of the integral characteristics of vibrocentrifugated concrete are analyzed. The most effective will be the use of clamps with a height of technological projections of 5 mm, a length of 20 mm and a step between them of 30 mm, the vibration mode is alternating. At combinations of technological parameters of vibrating vibrocentrifugal concretes have better values of integral characteristics.
