Influence of selected micro additives on thermal conductivity and surface microstructure of modified gypsum

Keywords: thermal conductivity, micro additives, surface microstructure, nanomaterials
Abstract:

The presented work includes experimental data on the influence of micromaterials on thermal conductivity
of gypsum. In this research used: microspheres, aerogel and polymer hydroxyethyl methyl cellulose. The
polymer and the aerogel are used as an additive in the weight fraction, up to 1% and the microspheres in the
weight fraction, up to 10% of gypsum. For the purpose of measuring of thermal conductivity, a non-stationary
method with the Isomet 2114 experimental setup was used. A decrease of thermal conductivity and density
with added microproducts were observed because of structure modifications of the gypsum product. Additional
microscopic images of the fractures of modified gypsum were made.
