| Ringkasan: | The higher demand of using polyethylene terephthalate (PET) bottles has made it
one of the major wastes generated by consumer. The large quantities of this waste
cannot be eliminated, however, the impact of the waste to the environment can be
reduced by changing it to a sustainable material in construction industries; where it
can be evaluated as lightweight aggregate. On this study, the shear behviour of
reinforced concrete contining PET aggregate using two point load configuration was
done. Prior to investigate the structural behaviour, the concrete physical and
mechanical properties for each 0%, 25%,50% and 75% of PET aggregate
replacement ratio was determined. As expected, the result of materials properties
which comprises of compressive strength test, split tensile strength and modulus of
elasticity (MOE) were decreased. The compressive strength decreased by 29%, 47%
and 52% for the replacement ratio of 25%, 50% and 75% respectively. Split tensile
strength also represent a 12%, 33%, 44% declination for each 25%, 50% and 75%
replacement of PET aggregate respectively. Furthermore, 15'76, 28% and 38%
decreasing for each 25% increment of PET aggregate were recorded for MOE test.
Despite all the reduction, one of the advantages of using PET aggregate as a
replacement for natural fine aggregate are the reduction of its density. For
replacement ratio of 50% and above, the density of the concrete fall into the
classification of lightweight concrete based on the requirement by ACI2 13R-03.For
structural beam test, it is shown that the reinforced concrete containing PET
aggregate behave in fundamentally the same manner as its normal weight concrete
with the difference in the performance of the parameter being tested. After that, the
experimental shear force were compare to the theoretical shear force compute by
BS8 1 10, ACI 3 18R-02 and Eurocode 2 where Eurocode 2 give a closer prediction to
the experimental result. |
