Proportioning based on the principles of absolute volume method was used to obtain specific
properties of lightweight concrete of oil palm kernel shells (OPKS). The sand content was
determined depending on the cement content and OPKS/sand ratio. The trapped air volume of
5% and Water/cement ratio of 0.45 were fixed according to previous authors' works. The cement
content ranged from 400 to 550 kg/m3, and the OPKS/sand ratio ranged from 0.4 to 0.75. The
mixture proportions of C:S:OPKS in weight of 1:1.60:0.96 and 1:1.53:0.99 with cement content of
450 kg/m3 resulted in values for workability (≥20 mm), density (1800 ≤ d ≤ 1900 kg m3) and
cylindrical compressive strength (≥ 15 MPa), which are recommended by ACI and British Code
for structural lightweight concrete. This study, as part of efforts toward a structured method of
proportioning of eco-friendly composite, demonstrates the possibility of linking mix proportions
to properties of lightweight OPKS concrete. |
