Original Abstract

Moisture plays very an important role in insulation materials from the view of possible degradation of thermal insulation properties. During the development of lightweight, thermal insulation plasters based on silicate were used special hydrophobic agents based on oleates and stearates. The aim of research works was to study the moisture transport in these developed materials that have been burdened with permanent moisture effect. Two non-destructive methods were used for monitoring of moisture transport; method of electrical impedance spectroscopy (EIS) and then was made determination of mass moisture using the apparatus – capacity moisture meter. Evaluation of measurement results demonstrated a substantially lower moisture sensitivity in comparison with commonly used thermal insulation plasters in Czech Republic.
