The paper presents the results of studies of magnesia compositions of porous structure. The possibility of pore formation in the structure of magnesia materials by various technological methods is shown. It was found that the high adhesive capacity of magnesia binders allows the use of fillers of various origins in compositions. The characteristics of magnesia compositions containing an ash microsphere, expanded polystyrene, expanded granules based on liquid glass, and porous magnesia granules are determined. A combination of porization methods is proposed for the formation of low-density magnesia compositions. A comparative analysis of the mechanical and thermal properties of porous magnesia compositions of various preparations is carried out. The advantages of complex porization of magnesia compositions due to a combination of mechanisms of foaming, gas formation and insertion of fillers of a porous structure are revealed. Magnesia compositions containing integral fillers of various shapes and origins are proposed. Multi-component compositions are characterized by a density of 540 kg/m3 and a compressive strength of 4.1 MPa. The impact of the method of preparing the molding mixture on the strength of porous structures is established. Porous raw materials were developed to produce granulated magnesia aggregate based on caustic magnesite and wood particles. Magnesia aggregate granules are used to obtain granular-cellular and coarse-pore structure of compositions.
