Fire-Resistance of Styroferrocement Sandwich Panels

Engineering and Technology Journal, 2016, Volume 34, Issue 6, Pages 1150-1160

This paper investigates the effect of fire on ferrocement sandwich panels. The experimental program consisted of fabricating and testing nine panels (400X400x30 mm in dimensions). The variables were type and number of mesh and Styrophoam content. A special arrangement was designed to create the effect of fire on panels. Test results showed that ferrocement panels have an endurance of fire when compared to control panels which may provide a desired protection to fire. In-spite-of wire mesh cracks, in plane cracks occurred when more volume fraction of mesh included. Whereas Styrophoam content affected the number of in-plane cracks. Plastic wire mesh had no significant effect on the wire mesh-induced cracks

This paper represents an experimental program on the behavior of SCC columns under fire. The research includes testing reinforced SCC columns subjected to various loading levels and heating rates. Nine columns were tested under concentric and eccentric loading and two burning rates (400 and 700oC) for 1.5 hour period of exposure at 60 days age. The paper represents the main results including the residual ultimate load carrying capacity, maximum crack width, axial deformation, crack pattern, the measured concrete and steel temperatures and axial displacements. It was found that the predicted load carrying capacity of SCC columns by the three codes which are (ACI-318/08, BS-8110/97 and Canadian/84), was unstable after burning except for the BS Code equation which was able to predict load capacity after exposing to high fire temperature levels. Valuable conclusions on the effect of loads and heating on concrete explosive spalling are shown in the paper.
