Abstract
The aim of article is to present the analysis results of damping parameters of vibrations as well as material features of reinforced concrete structures with the addition of zeolite tuffs and plasticizer. The first part describes the properties of zeolite and the impact of its addition on concrete parameters. The main part demonstrates the results of analysis on damping parameters of vibrations of reinforced concrete plate models. They contain a modified binder in which the part of cement was replaced by zeolite. The values of damping parameters were determined by the collocation method and only the first frequency of models free vibrations was taken into account. Moreover, the material characteristics of modified concrete were also determined, such as, compression strength, measured after 3, 7, 14, 28 days, frost resistance, penetration depth of water under pressure, abrasion, and the value of Young’s modulus as well as Poisson’s ratio.
