AbstractAbout the AuthorReferences
In the article material science problems of gypsum materials for restoration parts, elements of stucco in the architectural monuments in Russia. Traditional plaster mixtures have a high average density of up to 1900 kg/m 3 , which is unacceptable for a restoration of the weakened wooden load-bearing structures of palaces and other objects. Known to facilitate bulking in a plaster mixture: sawdust, expanded perlite and vermiculite, granules of foamed glass, foam, hollow ceramic microspheres lead to the loss of white and a sharp decrease in strength. The authors suggest for the high-quality restoration lightweight gypsum materials white color with hollow glass microspheres (HGMS), hydrophobic-plasticizing additive. It is possible to obtain gypsum grades G5 and G4 at an average density of 1102 and 531 kg/m3, respectively. The article presents x-ray diffraction and microstructural studies and proven that PSMS and supplements features could have their significant effect on the interplanar distances of the lattice, the intensity of peaks, their angles and dimensions of crystals of gypsum matrix.
