Abstract(s)
The most used insulating materials have advantageous technical characteristics
for construction, such as low cost, assuring to save fuel and energy resources. At
the same time, there are significant disadvantages such as: the combustibility of
a number of insulants; presence in the composition of harmful substances that
pollute the environment; the unsolved problem of utilization of thermal
insulation materials after use, as well as the high cost of energy for production.
Plant raw material is a significant reserve for the production of thermal
insulation materials in various regions of the world. Currently, in the countries
of Europe, special attention is paid to the use of plant waste in the technologies
for obtaining thermal insulation materials.
The results of practical experimental studies indicate the high efficiency of the
use of crop waste as a raw material for obtaining thermal insulation materials
with high thermal insulation characteristics.
In this regard, studies aimed at obtaining a new thermal insulation based on
plant raw materials, as well as the search for a new environmentally friendly
binder providing a decrease in the sorption moisture content of the insulation.
The purpose of the dissertation was to obtain environmentally friendly thermal
insulation materials based on vegetable raw materials of natural and agricultural
origin.
Compositions were developed of new thermal insulation materials based on a
mixture of crushed reed and straw, creating a new method for the introduction of
rosin into the aggregate mixture, which ensures even binder distribution,
regardless of the amount of thermal insulation material.
The electron microscopy of the reed and straw structure, revealed the
mechanisms that determine the physical properties of insulation.
The experimental data on the physical properties of thermal insulation slabs,
including average density, thermal conductivity coefficient and moisture
sorption, allowed to conclude that the developed compositions have
characteristics compatible with their application in construction.
