Precast Lightweight Foam Concrete (PLFC) sandwich panel is one of the best
options in building industry. The applications of PLFC mostly are in high rise
building such as flat, school building, apartment and others because the foam
concrete cannot sustain much load such as normal concrete. Due to the concept of
sustainable construction, some manufacturers at the building construction need to
find a new way of achieving the objectives and sandwich panel appear to fulfill their
needed. This thesis is intended to study the precast concrete sandwich wall panel
which is focused on compressive strength capacity, distribution of stress and strain of
window opening panel and observed failure and crack pattern. The material
properties of lightweight foam concrete wall such as compressive strength and
density is also tested.
The dimension of panels was casted as 1000mm×1000mm×100mm and the
opening at the centre with size 375mm×375mm. Experimental results of precast
lightweight foam concrete (PLFC) was compared with computational results and also
previous experiment result.
The test result showed that the density of LFC wall was 1803.8 kg/m3 – 1873.13
kg/m3 and considered as low density or lightweight concrete. Its compressive strength
based on cylinder specimen was 15.36 MPa. The panel compressive strength was 26
MPa. The ultimate stress of the panel structure was about 15 MPa then starts the
crack till maximum load of 27.5 MPa before breaking.
