Abstract

This paper presents the research on the structure and compressive stress or compressive strength of mineral wool products. The products of chaotic, directional and combinative fibres structure have been studied visually and microscopically. During mechanical tests it was determined that compressive stress (compressive strength) of the stone wool products is dependent on the direction of the load working to the product major face, test specimen dimensions, force increasing rate, fibres distribution (orientation) and methodical peculiarities.


Mineralin­is vatos plokščių stiprio gniuždant savyb­es: struktūros anizotropiškumo ir metodinių veiksnių įtaka


Santrauka. Pateikiami mineralin­s vatos gaminių struktūros ir gniuždomojo įtempio ar stiprio gniuždant tyrimai. Vizualiai ir mikroskopiškai tirti chaotiškos, kryptingos ir mišrios plaušo struktūros gaminiai. Mechaninių bandymų metu nustatyta, kad akmens vatos gaminių gniuždomasis įtempis (stipris gniuždant) priklauso nuo apkrovos veikimo krypties, bandinių matmenų, apkrovimo greičio ir plaušo išsid­stymo (orientacijos) bei metodinių ypatumų.


Reikšminiai žodžiai: mineralin­ vata, akmens vata, plaušai, struktūra, gniuždomasis įtempis esant 10 % deformacijai, stipris gniuždant, deformacija.
