Kholdaieva M. Structure and properties of polystyrene concrete with filling of microspheres

Object of researches: theoretical and physical models psevdoyacheistoy structure of polystyrene and polystyrene samples of density from 500 to 700 kg/m3, and the corresponding composition, but without the foam filler, the samples of the mortar as an analogue material interpore partitions; a purpose improving physical and mechanical properties of polystyrene by the directed structure formation at the expense of prescription factors; methods are the experimental studies were made using standard and special methods using certified means of measuring equipment and test equipment. In determining the structural parameters is applied experimentally - calculation method. To process and analyze the results of experiments applied the methods of mathematical statistics; results - developed technological processes fragmented blocks of polystyrene wall (a construction company introduced "PRACTICE", Odessa); proposed structure is structurally - polystyrene thermal insulation medium density 500-550 kg/m3 with improved mechanical and heat-shielding properties (patent number 39515, Ukraine IPC 2009, WITH 04 IN 14/02 "Mixture for the preparation of polystyrene"), based on the proposed composition of the polystyrene holds the erection of walls of buildings with total area of 450 m2; novelty - substantiated and experimentally confirmed the feasibility of introducing a mixture of polystyrene microspheres of aluminosilicate, found their best content and the size ratio; proved and experimentally confirmed the need for the introduction of polystyrene and an air mixture of plasticizing additives, is most effective supplements and their optimal dosage and in polystyrene at macrostructural level marked structural elements and developed an algorithm for calculating their volume content, identified and analyzed the dependence of physical and mechanical properties of polystyrene on the parameters of the structure, set according to thermal and strength properties of polystyrene from the content components of the mixture revealed the range of prescription and technological factors that ensure obtaining polystyrene with predetermined structure and properties.
