This “product note” in a trade publication discusses a polymer admixture designed to increase concrete’s damping properties and therefore increase the decay of impact-induced vibrations. The liquid additive is similar to styrene-butadiene rubber (SBR) admixtures that are commonly used in pavement to improve durability, but has been modified by adding vegetable gum in the suspension. The article summarizes how the product works and how the appropriate dosage is selected and the strength reduction calculated.
