Abstract

Oil palm shells (OPS) has been used as an aggregate in concrete mixture, replacing the normal
sense aggregate in many countries, since long time, and it is still an important aggregate in terms
of quantity used. In Malaysia, the development of using oil palm shell as lightweight aggregate
in construction industry, especially in structural application started about 30 years ago. Today;
concrete is one of the most versatile construction materials. Many researchers found that OPS
light weight concrete performances need to be enhanced especially when used for structural
applications. In this research work an efforts were taken place to enhance OPS concrete
performances by using bamboo fibers. Compressive strength, impact energy absorption and
crack resistance were investigated for different mix design of bamboo fiber content and good
results were gained. The compressive strength decreased marginally the percentage of bamboo
fiber of 2% by cement weight. The impact energy absorption for 1% bamboo fiber increase
about 1.9 times for service (first) crack and 1.5 times for the ultimate (failure) crack as compared
to the service (first) crack and ultimate (failure) crack of the control sample with no bamboo
fiber respectively. However, the impact energy absorption for 2% bamboo fiber increase
considerably about 2.3 times for service (first) crack) and 1.8 times for the ultimate (failure)
crack as compared to the service (first) crack and ultimate (failure) crack of the control sample
with no bamboo fiber respectively. As such the 2% percentage of bamboo fiber has better
performance than 1% percentage of bamboo fiber in term of impact energy absorption and crack
resistance especially under service (first) crack condition. The difference in bamboo fiber length
has only marginal effect on the impact energy absorption or surface crack resistance for service
(first) crack and ultimate crack condition. The results show that oil palm shell light-weight
concrete with bamboo fibers indicate a potential future of this material to be used as an impact
resistance composite structures.
