Influence of Variotropy on the Change in Concrete Strength under the Impact of Wet–Dry Cycles

One of the most dangerous types cyclic effects, especially inherent in several regions world, is alternating impact wetting and drying on concrete reinforced structures. In current scientific literature practice, there not enough fundamental applied information about resistance to variotropic concretes obtained by centrifugal compaction methods. The purpose study was investigate effect various technological, compositional, other factors final cycles moistening drying. For this, special methods for testing samples were used work. It has been established that after strength gain as a result hydration, tendency loss due wear. An acidic medium negative characteristics made using technologies, compared with neutral alkaline media. when moistened an greater than vibrocentrifuged turned out be resistant aggressive environment drying, centrifuged vibrated concrete. drop up 7% less 17%
