The Influence of the Relative Content of Peat and Mineral Binder on Thermal Insulation Composite Performance Characteristics
The relationship between the performance characteristics (e.g., thermal conductivity, specific density, and compressive strength) of a peat heat-insulating composite and its chemical composition has been established. It has also been experimentally proven that high-lying peat and limestone from...

description |
The relationship between the
performance characteristics (e.g., thermal conductivity, specific density, and
compressive strength) of a peat heat-insulating composite and its chemical
composition has been established. It has also been experimentally proven that
high-lying peat and limestone from the Vologda Oblast deposits correspond in
chemical composition and structural features to the requirements for producing
heat-insulating materials (HIMs). Composite samples with different chemical
compositions were obtained under laboratory conditions. To increase the
mechanical strength and setting speed when collecting samples, a stage of peat
steaming with water vapor and carbon dioxide was provided. HIM testing using modern analytical
methods has proven a relationship exists between the content of high-lying
peat, quicklime in samples, and
their performance characteristics. The optimal chemical composition for
obtaining composites was selected. High-lying peat with a moisture content of
30.0% after steaming and quicklime content of 29.0% ensured the production of a
composite with the following indicators: thermal conductivity of 0.041 W/m?°C;
average density of 259 kg/m3; compressive strength of 3.02 MPa; and
toxicity index of less than 0.5. The established dependence enables simulation
of the technological process and obtains materials with the desired properties. |
