| Title of the article | The study of influence of filler material on the thermal properties of fine-grained concrete |
| Abstract. | The analysis of thermal insulation materials and facade systems of buildings and constructions, which are important for the thermophysical properties was shown. With this aim the article presents the research on the influence of filler material on the thermal conductivity coefficient and the thickness of the enclosure walls. The conductivity coefficient was measured by the method of heat flow on the ITP-MG4 device. The filler material is a lightweight powder of a modified diatomite with a density of 700 kg/m3 and a grain size from 0,16 to 1 mm. Considered only fine-grained concrete. As a result, the introduction of the filler material in an amount of 10 and 20 % instead of cement in sand concrete reduces its conductivity by 34 % and 65 %, respectively, in the expanded clay lightweight concrete by 7 and 13 %, and in the polystyrene only by 5 % with the introduction of 20 % of the filler. This fact is very important for mortars, allowing by using available, inexpensive materials to design walls that fit into the ideology of the efficient heat energy saving of modern buildings, including high-rises. The use of filler material is most effective in concrete with higher density. |
