Correspondence of the research to the priority directions of the development of science and technology in the republic. This study was carried out in accordance with the priority direction of development of science and technology of the Republic of Uzbekistan: II. "Energy, energy and resource saving".
The degree of knowledge of the problem. Many foreign scientists have been involved in the modification of gypsum concrete, the scientific basis for increasing its thermal efficiency in the world practice - Yu.M.Bazhenov, A.T.Baranov, S.A.Gusenkov, A.S.Kolomasky, I.T.Kudryashev A.A.Laukaitis, V.A.Martgnenko, W.K.Makhambetova, LV.Morgun, Sh.M.Rakhimbaev, V.A.Pinshker, Yu.V.Pukharenko, G.P.Sakharov, L.B.Svatovskaya, I.B.Udachkina, T.A.Ukhova, Yu.D.Chistov and others.
Leading scientists in the field of building materials in the republic-A.B. Ashrabov, E.U.Kasimov, N.A.Samigov, A.A.Tulaganov, A.N.Adilkhodjaev, B.A.Ascarov, X.A.Akramov, A.A.Tokhirov, S.A.Khodjaev, N.Abbaskhanov. X X.Kamilov, A.T.Jalilov, M.W.Karimov, Z.M.Sattarov, I.I.Kasimov S. Razzokov, A. I. Khamidov, A. M. Rakhimov, B. Sh. Rizaev and others made a significant contribution to the development of the production of building materials in Uzbekistan.
An analysis of previous studies shows the widespread development of the production of gypsum composite materials and their use. However, in the construction industry for the production of building materials, with sufficient resources in the Republic, for the production of gypsum concrete products, consistent research has not been carried out in this area, industrial waste containing gypsum inclusions has not been sufficiently studied, as well as the production of energy-saving gypsum composite materials based on fillers from industrial waste of marble and travertine, indicates the need for research in this area.
The connection of the dissertation research with the plan of research work of the higher educational institution where the dissertation was completed. The dissertation research was carried out at the Department of Production of Building Materials, Products and Structures of the Fergana Polytechnic Institute, according to the completed research of the practical project "Obtaining effective building materials and structures based on local raw materials (on the example of the Fergana industrial zone), studying and improving their physical and mechanical properties."
