| Summary: | This thesis deals with the use of palm oil fuel ash (POFA) as the cement
substitution to the Ordinary Portland Cement for the use of cement mortar. It is an
attractive approach whereby POFA has been abundance in Malaysia and little
research has been done on it. Furthermore, this research also involved the percentage
of water absorption of each mix at
7th
day and
28th
day of cement maturation. The
main objective of the study is to find out the best modulus of rupture (apparent tensile
strength) from the various amount of POFA added into the mix and the best rate of
water absorption from the samples. The tensile tests were carried out for different
mortar beam samples with the used of strain gauge. Both
7th
day and 28" day cement
mortar maturation days were tested to compared its early strength and strength upon
maturation. Graphs were plotted to make compares between the samples. The samples
are then to be kept until all the testing is done on
7th
and
28th
days. The samples were
then to be dry in oven for 24 hours before conducting the water absorption test. Dry
samples were then immersed in water for another 24 hours to get its best water
absorption rate. Data were tabulated and analysed. The optimum percentage of POFA
that gives the optimum modulus of rupture for the cement mortar beam is 2% whereas
for the water absorption, it can be concluded that as amount of POFA increased, the
water will be less absorbed by the cement mortar due to POFA's fine properties that
fill in the void in the cement mortars. The variation content of POFA was 0%, 1%,
2%, 3% and 4% by total cement weight. |
