Abstract
Brick construction is widely uses in all parts of the world over the last century
especially wall construction. The use of these materials is closely related to several
factors, among which are easily obtained, cheap and easy job control. However, there are
some disadvantages arise in the application of brick construction which brick wall will
eventually crack wherever exceed the load capacity of the brick. Therefore, the study is
focus on the strengthening method on wall construction without changing the
construction materials. In this study, strengthening method using fibre reinforced
polymer method is selected in order to observe the maximum load capacity and compare
behaviour against the loading that can be obtained when strengthen by fibre reinforced
polymer. Characterization tests such as absorption test and compressive strength test
were conducted on concrete masonry unit (CMU) to determine its characteristics before
mortar mix were used as a binder for the specimens. Compression and flexural tests were
conducted to characterize the mortar mix used. A total of 12 prisms specimens with four
different conditions were produced for the compressive strength test. Those prism
specimens are classified as strengthened with CFRP in horizontal orientation (A),
strengthened with GFRP in horizontal orientation (B), control specimen without fibre
polymer (C). Each condition has a total of three specimens each to compare their
outcomes. The results of observations and tests found the average value of the failure
load is as follows (A) 148 kN, (B) 186 kN and (C) 180 kN. The conclusion that can be
made is strength (B) which specimen strengthened with GFRP in horizontal pattern is
the highest compare (C) and (A) which prove it can increase the load capacity of structure
and crack pattern could be controlled.
