SUPERIOR MICROSTRUCTURE OF HIGH-PERFORMANCE CONCRETE FOR LONG-TERM DURABILITY

Recent advances in using calculated packing diagrams to optimize cement and concrete materials offer the promise of superior product characteristics achieved by increased packing efficiency. A high packing efficiency with adequate mixing and placing techniques results in the formation of a fine microstructure that results in low permeability. The low permeability causes increased resistance to aggressive forces from the environment, which together enhance its long-term durability. The favorable interaction among physical and chemical phenomena gives rise to better long-term performance, whether the application is structural, chemical (such as in waste management), or a combination (as in highway concrete).
