| This research is concerned with a new type of ferrocement of polystyrene concrete, which has several advantages compared to ordinary reinforced concrete plates, such as lower density, abrasion resistance, compressive and flexural strength. The experimental program consisted of casting and testing of 24 ferrocement plates. The dimensions of the ferrocement plates were (600×300×40) mm in (length × width × height) respectively. The effect of various factors such as mix proportions of cement to polystyrene (C:P) ratio has been investigated, both by destructive and non-destructive methods. The experimental results of the compressive strength of mortar mix 1:1 and using (1:1, 1:3 and 1:5) the cement to polystyrene (C:P) ratio by volume were increased by (6.0, 9.9 and 12.2 )% and (11.7, 18.1 and 20.6)% at (60, 90) days age respectively, while for mortar mix 1:2 were increased by (6.3, 10.2 and 10.5 )% and (12.6, 16.5 and 19.0)% at (60, 90) days age respectively. On the other hand, increasing (C:P) ratio was found to decrease the stiffness constant and dynamic modulus of elasticity of polystyrene concrete plates. Also, the analysis of the experimental results showed that the dynamic properties such as, dynamic modulus of elasticity and stiffness constant increased linearly as the volume fraction of steel wire mesh or specific surface area was increased | ||
