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...
