Physical and Mechanical Characteristics of Variotropic Concrete during Cyclic and Continuous Sulfate Attack

The concrete of numerous buildings and structures is at increased risk due to various kinds aggressive pollutants. In this regard, it necessary implement take additional actions, among which the so-called technological methods for structure property modification are promising. These comprise improvement modernization existing technologies produce most effective building before introduction steel reinforcement. One proven design solutions use centrifuged vibrocentrifuged an annular section with a variotropic structure. aim work was study physical mechanical properties concretes when exposed sulfate attack. As result cyclic impact attack, mass loss smallest in comparison (17% less) vibrated (37% less). cube prism strength (20% 18% less, respectively) (42% 38% respectively). attack rate, as depth penetration destruction, 46% less than 65% concrete.
