Structural Behaviour of Ferrocement Panels Under Radiant Heating

In the present work the influence of heating on the flexural resistance of ferrocement slab specimens are carried out. A total of one hundred and sixty eight ferrocement slab specimens 300*300 mm were cast, cured, heated, and tested under central point loads. The main parameters were 30 o C (room temperature), 100-800 o C with a graduation of 100 o C , mixing ratio of cement to sand (c: s), thickness, and number of wire mesh layers. The behavior of specimens was observed by reading the load-deflection at the central point of the specimen. In addition, the effect of heating on the compressive strength of cement mortar, and wire mesh used in casting the specimens were studied. It is concluded that the strength of ferrocement slab specimens were dropped sharply at a temperatures between 500-700 o C and the specimens were damaged at 800 o C. Also in crack stage, the slope of load-deflection curves were decreased and approaches zero at temperature 700 o C.
