Opis:
W artykule omówiono technologie wykonywania budynków jednorodzinnych przy użyciu pustaków styropianowych, zasady wykonywania przegród budowlanych oraz nowe technologie dotyczące tego typu materiałów budowlanych. Przedstawiono zalety i wady domów jednorodzinnych wykonanych z pustaków styropianowych. Poruszono również problem izolacyjności cieplnej przegród budowlanych wykonanych w tej technologii w odniesieniu do obowiązujących przepisów prawnych.
The article discusses the technology of building detached houses with use of hollow styrofoam blocks, rules for the building envelope, and new technologies for this type of building materials. It also presents the advantages and disadvantages of detached houses made of Styrofoam blocks. Also raised the problem of thermal insulation of building partitions made in this technology, in relation to the effective legislation.

Opis:
The study was conducted to determine the biodegradation of Expanded Polystyrene (EPS) (Styrofoam) Blocks as feedstock to Tribolium castaneum (Red Flour Beetle) Imago. Three-hundred-sixty (360) Tribolium castaneum (Red Flour Beetle) Imagos were collected and acclimatized for two days before being exposed to experimentation. Incubation boxes were made using plywood. Three set-ups were prepared, with 30 Tribolium castaneum (Red Flour Beetle) each. Seven (7) grams of Styrofoam Block were placed in Set-up 1, seven (7) grams of Styrofoam and seven (7) grams of Rice grain Bran in Set-up 2 and seven (7) grams of Rice grain Bran in Set-up 3 with three replications each. Mean percent mass loss of Styrofoam and Rice grain Bran, mean percent mass loss and survival rate of Tribolium castaneum (Red Flour Beetle) were measured at 5th, 10th, 15th and 20th day incubation periods. Maximum mean percent mass loss in the different set-ups was observed at the 10th, 15th and 20th incubation period, with loses of 7.14%, 10.71% and 10.71%, respectively. Meanwhile, maximum mean percent increased weight of Tribolim castaneum (Red Flour Beetle) was observed at the 10th day incubation period, with 13.51%, 44.44% and 37.93%, respectively. Microscopic observation, of a dark white smear on the gut of the specimen indicates that Tribolium castaneum (Red Flour Beetle) Imago really masticate and biodegrade the Expanded Polystyrene (EPS) (Styrofoam) blocks. The survival rate of Tribolium castaneum (Red Flour Beetle) in the diverse set-ups showed no significant difference. This implies that ingestion of Styrofoam Block had no lethal effects on the natural weight variation and health of the Tribolium castaneum (Red Flour Beetle). Hence, results indicate that Expanded Polystyrene (EPS) (Styrofoam) Block can be a feedstock for Tribolium castaneum (Red Flour Beetle).

Opis:
The present paper tends to investigate the merits and demerits of chromite and Styrofoam ceilings in concrete structures. Since in lots of buildings and structures chromite and Styrofoam used in ceilings, there are problems with their implementation cause a bunch of advantages and disadvantages. Generally, precast beams or in short joist with blocks including both chromite and concrete, if properly designed, calculate and implemented have less tremble than the in situ concrete ceilings and composite due to the thickness of the ceiling blocks. But this is a general issue and it varies in different circumstances and conditions. For example, the vibration of the composite ceilings will be much less in the cases of underpinning both of the primary and secondary beams during concreting. The tremble of ceilings with old style blocks I mean Concrete masonry unit (concrete zigzag slab) and Composite steel concrete precast beams is also less than others of this kind Because of the underpinning during execution Polymer Styrofoam is white in color, and moisture, heat and sound insulation which is produced in petrochemical plants. This material is available in very small volumetric volumes (1.04 to 1.09 g / cm3) in different gradation of tiny and big can be found in form of granules, sheets, and blocks of various sizes and thicknesses. Cutting it off with cutting machines or by hot wire is easy to do. In this study, the chromite and Styrofoam ceilings are examined and their advantages and disadvantages of them in concrete structures are investigated.
