Abstract
Pulsed terahertz spectroscopy is widely used in scientific research of fast processes in various structures at nano-, meso- and macrolevels. Terahertz radiation has not been not applied in construction technologies until very recently. With the development of terahertz spectroscopy, it successfully complements classical methods of physical and chemical analysis of building materials for various engineering purposes, especially for heat-insulating materials in a wide range of density and electrical insulating properties. These studies are currently relevant for the development of compositions and technologies of effective thermal insulation materials based on wastes of the pulp and paper industry, including various types of substandard raw materials.
Purpose: The aim of the work is to substantiate the application of terahertz spectroscopy in studying the formation of curing structures of building materials of different nature.
Methodology: Terahertz spectroscopy and strength analysis to study ongoing processes.
Research findings: It is found that the system based on modified polyurethane and paper filler, has the highest performance characteristics. It is shown that the highest absorption of terahertz radiation in the samples occurs in the frequency range above 1 to 2 THz.
