Szulej J. Preliminary studies of dynamic parameters in multi-material structures with the addition of zeolite / J. Szulej, P. Ogrodnik // Вісник Національного університету "Львівська політехніка". - 2014. - № 781. - С. 177-187.

The aim of this article is to present the results of preliminary research of the damping parameters of vibration in the constructions with the addition of zeolite. The first part of the article deals with the characteristics and application of zeolite. It describes mainly the impact of the addition of zeolite on the concrete parameters. The main part of the article presents the research outcomes of the damping parameters of the three models of plate-beam. The models contain modified binder in which the part of the concrete is replaced by the zeolite (with more than 85% content of the clinoptilolite). The values of the damping coefficients of vibration are determined by the collocation method as well as the method based on the estimation of kinetic energy of the vibrating system. The damping coefficients of the first three models of model vibration are determined.
