High tensile bollard structure using macro synthetic fiber
The usage of bollard is very important in protecting buildings. It can prevent vehicles from passing through the building. But the public now is less sensitive about the use of bollards. They assume the use of bollard is wasteful and for aesthetic only. Therefore, most buildings did not install bo...

The usage of bollard is very important in protecting buildings. It can prevent vehicles from passing through the building.
But the public now is less sensitive about the use of bollards. They assume the use of bollard is wasteful and for aesthetic
only. Therefore, most buildings did not install bollards to protect the building. Besides that, there are also mounted
bollards installed that are inappropriate to that place. For example, some bollards installed around buildings are not
concrete type that can withstand strong impacts. Furthermore, some important and historic buildings need to install an
explosive-proof type of bollard as building protection. The methods used for this research were non-destructive test and
destructive test. Non-destructive test is slump test and destructive tests are compression test, tensile test, flexural test,
and air blast test. Seven mix were used and tested in this research. From the compression test result, it shows that
concrete mixed with 0.5% of macro synthetic is much stronger than control sample and other mixtures. From the tensile
test, it shows that the control sample of the concrete achieved tensile strength of 3.48 N/mm2 while the mixed concrete
with 0.5 % mix of macro synthetic fiber gave higher tensile strength. The flexural test shows that the concrete mixed with
percentage ratio of 0.5%, 1.0%, and 1.5% of macro synthetic fiber gave higher strength than the control sample which
is only 2.77 N/mm2. Based on experiments that have been carried out, it can fulfil objective one, which is to evaluate the
type of blast safety for building envelope with the concrete bollard grade 30. Quality of concrete in terms of strength,
tensile, and flexure of the proposed material with 0.5% of macro synthetic fiber can produce the same quality and meets
the quality grade C30 concrete. |
