Abstract
The government aims now to study some of the different systems
to construct residential buildings with economical cost. These systems
include precast concrete slabs, precast prestressed concrete slabs such as
Hollow Core slabs, Glass Reinforced Concrete slabs and Sandwich Panel
slabs system.
Fire behavior of concrete is linked to the temperature-dependent
material properties. Since the thermal diffusivity is rather low, compared
to steel, strong temperature gradients are usually generated within fireexposed
concrete members. Together with the high thermal inertia, this
means that the core region may take a long time to fire.
In this investigation, an experimental program has been made to
study the effect of high temperature and fire on some items such as
temperature, concrete cover, cracking load, cracking patterns and mode of
failure as well as the ultimate failure load on different R.C. slabs system.
The test specimens consist of twelve slabs; four slabs are from reinforced
concrete, four slabs are from Sandwich panels system, two from Glass
Reinforced concrete system and the last two are from Hollow core slab
system.
The experimental program consists of testing twelve slabs had an
overall width, length and depth of 1200 mm,1200 mm and 120 mm
respectively. The slabs were simply supported with a clear span of 1100
mm. The type of reinforcement of slabs is different from each other.The government aims now to study some of the different systems

mm. The type of reinforcement of slabs is different from each other.
The experimental program is divided into two phases, two slabs
from RC slab system and the sandwich panels were tested as a control
slab and the other two slabs were loaded while exposed to fire and for the
Glass Reinforced concrete and the Hollow core slabs only one slab was
considered as a control slab and the other one is loaded while exposing to
fire.
