THE RESEARCH OF PHYSICAL – MECHANICAL CHARACTERISTICS OF ECOLOGICAL THERMAL INSULATION

Abstract

In this article the thermodynamical and mechanical research of organic thermal insulation slabs prepared from cardboard refuse and synthetical binding material is presented. For this aim the samples with different amount of binding material, different density and different thermal insulation material granulometry were used. During the research it was established that granulometric composition of thermal insulation material and amount of the binder influence density of the samples. In all cases density influences the alternation of thermal conduction coefficient. The lowest thermal conduction have the samples prepared from milled cardboard, bolted through 1.5 mm bolter. During the research of mechanical characteristics it was determined that the best strength characteristics have the samples prepared with bigger amount of the binder and higher density.
