The need to acceleration the provision of residential homes requires the government
tried innovative construction system using concrete sandwiches expanded
polystyrene used as wall construction. This construction has advantages such as
having a relatively lighter weight, relatively more economical prices, and the ease
and speed of construction. This construction is expected to reduce the risk of
damage due to earthquakes because it has a relatively light weight which is one of
the requirements for earthquake resistant houses. To increase the bearing capacity
of expanded polystyrene concrete panel walls to be a structural wall, the alternative
is to use reinforced coating material. In this study using precast specimens obtained
from the precast manufacturing with a length of 1800 mm, width 610 mm, and thick
75 mm. Strengthening using the Calcium Silicate board. The type of calcium silicate
used is the Kalsi board. The test object is glued using sika glue and then drilling, if
it is has done to install the bolt as a sliding connector. Variations in this study are
expanded polystyrene concrete panels without reinforcement, with reinforcement,
and with reinforcement and bolt shear connectors. Testing based on SNI 03-3122-
1992 (Fibrous Lightweight Concrete Panel). The results showed that the average
value of the panel weight was 612,57 kg/m3, the elastic modulus was 942,37 MPa,
compressive strength of 2,52 MPa and water absorption capacity of 12,11%. The
highest compressive strength was obtained by the panel with a calibration of 1,18
MPa. This shows the addition of reinforcement layers will affect the increase in
strength |
