Title of the thesis:Lightweight concretes based on recycled plastic foams
Summary:The main propose of my work was to verify effects various doses of plastic recycle EVA (ethyl vinyl acetate) on properties of lightweight concretes. This idea was prompted by lack of polystyrene in the market and also large amounts of waste of foamed plastics, for which the application is looking for opportunities. Further aspect was that production of polystyrene pearls, used as a filler of lightweight concrete. In the production of samples was used as reference material foam recycled polystyrene. The main strength and heat-technical characteristics of lightweight concretes were watched. Dose of cement was constant in every sample (175 kg/m3) and dose of water was constant also (87.5 kg/m3). Share of filler components was changed only. Sweeps were made of only one filler (polystyrene or EVA) and in other sweeps were made of mixture from both fillers, in various proportions (3:1, 1:1, 1:3). During the measurements were recorded values of bulk density, which was increased by higher dose of EVA (300-390 kg/m3 after 28 days in moisture environment). Also results of the coefficient of thermal conductivity were increased, when was increased dose of EVA that I evaluate as a negative property (from 0.0704 to 0.0935 W/(m.K)) but differences between those results and result of polystyrene were minimal (from 0.0046 to 0.0277 W/(m.K)). The highest value of strength was recorded with 50% polystyrene and 50% EVA as filler. After made measurements of main properties, it is possible to claim that foam recycle EVA has a big potential as filler for lightweight concretes.
Key words:foamed plastic EVA, foam waste polystyrene, lightweight concrete
