Abstract
The current trend, with regards to the cost and energy savings, is to combine properties
of basic materials and try to obtain so called synergic effect with that we could get significant
amplification of their individual properties. The aim of this article is to assess whether this required
improvement of the physical properties occurs also for fiber-reinforced construction materials,
whose study has been the author work devoted for a long time. This work is focused on assessment
of changes in the acoustic attenuation of the basic plaster composites with addition of some high
strength fiber reinforcement. The chosen plasters materials are commonly used in building
constructions (gypsum, lime-cement, cement). Into those materials that in our case has become
the matrix, some basalt and glass fiber dispersion of length 8.5 and 12 mm have been added. An
impedance tube was used to the test of materials acoustic absorption. The results show the very
good acoustic absorption for all of the tested samples regardless on the ratio of used reinforcement.
