A “Toolbox” of Damping Treatments for Concrete Structures

摘要

The paper presents measures by which significant changes in the damping ofrnconcrete may be achieved. A variety of alterations in mix design were examinedrnexperimentally, and the most effective treatments involved the use of polymerrnadmixtures. Significant changes in damping were associated with the use of severalrntypes of styrene-butadiene rubber (SBR) latex, ethyl-vinyl-acetate (EVA) latex, andrnstyrene-acrylic ester (SAE), as well as a blend of SBR and partially-solidifiedrnvegetable gum. The polymer treatments resulted in frequency- and temperature-dependent damping properties.
