Abstract
In this paper a comparative analysis of thermal behavior of six partition walls with different thicknesses were presented. The walls were dimensions 3000 mm x 3000 mm made from autoclaved aerated concrete blocks with dimensions 625 mm x 200 mm and thicknesses 50 mm, 75 mm, 100 mm, 120 mm, 150 mm and 250 mm. All walls were exposed to standard fire test according the standard SRPS EN 834-1, non- combustibility test according the standard SRPS EN 1182 and surface spread of flame test according to SRPS U.J1.060. All walls were tested to fire resistance in vertical furnace with a data acquisition system, according to standard fire test. Standard furnace for testing construction consist of four two step burners in liquid fuel type of 296 kW manufactured by ECO FLAM. Two transmitters of differential pressure type 6321 manufactured by TESTO (Germany), with range 100 Pa installed inside the furnace were used for pressure measurement. Inside the furnace the temperature on six places wi...th thermocouple type K were measures. The measure ranges of thermocouple type K were -2700C to 13720C. The temperatures on unexposed fire side were measured in nine places with thermocouple type T with measure ranges - 2700C to 4000C of according the national standard SRPS U.J1.090. The obtained temperature results depending of the time of reaching the critical temperature were presented for each wall thicknesses. The five identical cylindrical samples with high 50 mm and diameter 45 mm for non-combustibility test has been used. All samples have been tested in standard furnace for non-combustibility test. The average temperature in furnace and specimens were presented. Surface spread of flame testing is carried out according to standard SRPS U.J1.060, if the coating material is based on organic or mixed materials. The samples for these test are with dimensions 900 x 230 mm.
