Abstract

The paper presents the experimental measurement of the thermal conductivity of the modified gypsum and the influence of added micro additives on this thermal parameter. The polymer and the aerogel are used as additives in the weight fractions 0.5%, 1% and 2% of pure gypsum and the microspheres in the weight fractions 5%, 10% and 15% of gypsum. The water-to-gypsum ratio (w/g) for all specimens was 0.75. For the purpose of measuring of the thermal conductivity λ, a novel non-stationary method was used. Based on the experimental measurements found the gypsum with polymer content resulted in more than 44% lower thermal conductivity in comparison to the specimen without hydroxyethylmethylcellulose as a result of the different porosity of the modified specimens. Decrease in thermal properties, were observed as an effect of microstructure modifications of the gypsum product. The gypsum with aerogel and microspheres content resulted in more than 35% and 42% respectively lower values in comparison to the reference sample without micro additives.
