Abstract
The purpose of this article is to present the results of the first stage of research on the damping parameters of vibration and the material characteristics of reinforced concrete structures with the addition of zeolite tuffs. The first part of the article describes the properties of zeolites as well as its impact on the concrete parameters. The main part of the article shows the partial results of research on damping parameters of vibration of reinforced concrete slab models. The models contain modified binder in which the portion of cement was replaced by zeolite (tested models and samples contained 0%, 10%, 20%, 30%, 40% of zeolite). The values of damping coefficients of vibration were determined by the collocation method, and only the first frequency of free vibration of models was taken into account. Moreover, the material characteristics of modified concrete were determined, ie compressive strength (after 3, 7, 14, 28, 56, and 90 days), frost resistance, water absorption, friability, as well as the values of Young modulus.
