Prefabricated ferrocement sandwich elements in fire conditions

Summary: In this paper the experimental results of two-dimensional non-stationary temperature fields of prefabricated ferrocement sandwich panels in fire condition, were presented. In order to determine resistance to fire, the temperature fields of two walls dimensions of 3000 mm × 3000 mm and a thickness of 190 mm made from precast ferrocement sandwich panels, were analyzed. The first panel has been insulated with styro-concrete, and the second with styro-concrete and expanded polystyrene. The panels were exposed to conditions of real fire corresponding to the standard fire curve defined by the standard SRPS EN ISO 834-1. The tests have shown that, due to the detonations that occur when the panels are exposed to fire, these panels have unpredictable behavior
