Thanks for everything.
ACKNOWLEDGEMENTS
Alhamdulillah, first and foremost, thank you to Allah S.W.T with His
companion, guidance, and wishes this project complete successfully. Thanks to my
supervisor, Dr. Mohd Ibrahim Safawi B.Mohd Zain for his help, guidance and
attention in accomplishing this thesis successfully.
Special thanks also for UNIMAS Civil Engineering Laboratory technicians
En Nur Adha b. Hj Abdul Wahab for their help and cooperation during laboratory
work. Their willingness to share their knowledge and time with me during the
research is a valuable experience.
I would like to express my utmost thanks and gratitude to my beloved family,
my mother, father, sister, brother in law, younger brother and my fiance. I would
never have been able to complete this thesis without your continuous love and
support.
Lastly, not forgetting to all my coursemates and friends, who give me support
and help whenever I needed them.
ABSTRACT
In the history of the construction industry, lightweight concrete or foamed
concrete is a special concrete which can very useful in the construction sector
because it is very lightweight and it can compact by itself at each angle of foamwork.
Many researchers have been done in overseas, and show that foamed concrete is free
flowing material which is ideal for wide range of application. Moreover, material
used to produce concrete is cheap to normal concrete. The objective of this thesis is
to determine strength of concrete by using different material such as superplasticizer
and without using superplasticizer follow by mixing by using water and without
using water. The addition of chemical admixture such as superplasticizer (in the
form of liquid) can help achieve as it can produce mortar of normal workability but
with an extremely high strength owing to a very substantial reduction in the
water/cement ratio. There are three test that been through at concrete laboratory such
as Flow Table Test, Curing Test and Strength test in order to understand and look out
character of the concrete. An inspection from this project can show the nature of
foamed concrete when strength test will be done.

ABSTRAK
Dalam sejarah industri pembinaan, konkrit ringan atau konkrit busa adalah
konkrit khas yang amat berguna dalam industry pembinaan kerana sifatnya yang
ringan dan boleh mampat dengan sendiri di dalam setiap ruang acuan. Banyak kajian
yang telah dijalankan di luar Negara, menunjukkan bahawa konkrit busa mempunyai
sifat yang mengalir dengan sendiri di mana ianya digunakan secara meluas.
Tambahan lagi, bahan yang digunakan untuk menghasilkan konkrit ini murah dan
dapat mengurangkan kos pembinaan. Tujuan kajian ini dijalankan adalah untuk
menentukan kekuatan konkrit dengan mengunakan bahan yang berbeza seperti bahan
menggunkan superpemplastikan dan tidak mengunakan bahan superpemplastikan
diikuti dengan campuran yang mengandungi air dan campuran yang tidak
menggunkan air. Penambahan bahan tambah kimia seperti superpemplastikan
(dalam bentuk cecair) dapat membantu untuk menghasilkan ciri yang lebih baik
dengan menghasilkan mortar dengan kebolehkerjaan biasa bagi mempunyai kekuatan
yang tinggi apabila nisbah airlsimen dikurangkan. Terdapat tiga jenis ujian yang
dijalankan seperti ujian kebolehkerjaan, ujian rendaman dan ujian kekuatan untuk
mengetahui dan melihat sifat-sifat concrete tersebut. Pemerhatian daripada kajian ini
menunjukkan sifat konkrit buih apabila ujian kekuatan dilaksanakan.
