In the research, cellulose-based polymer and aerogel were used as the modifying micro materials. For the purpose of measuring the thermal conductivity, a non-stationary method was used based on the “hot wire method”. A very precise set of devices for measuring and recording the temperature of the heating wire was used. In the presented solution, a single measurement took only one minute. Measurements were recorded with the help of a computer measuring system, with a sampling time of 0.01s. During the 60-second-long test, 6000 measurements of the heating wire temperature were collected. A decrease of the thermal conductivity and density of hardened gypsum with added micro materials was observed due to modifications of the structure of the final product. Experimental values of the thermal conductivity of the gypsum specimens with the addition of polymer and aerogel were respectively over 23% and 6% lower than the non-modified gypsum specimen.}, type={Article}, title={Analysis of the Thermal Properties and Structure of Gypsum Modified with Cellulose Based Polymer and Aerogels}, URL={http://journals.pan.pl/Content/118203/PDF/09_ACE-00014_B5.pdf}, doi={10.24425/ace.2020.135214}, keywords={thermal conductivity, micro additives, structure, hot wire method}, }
