| Summary: | Generally, concrete is one of the most mutual construction materials and is applied in a wide-ranging variety of application, alternating from pile to multistoreys buildings and from railroad connections to dams. A concrete with very less voids or spaces in it, which were fill with fine aggregates will increased the workability and reduces the quantity of cement required to produce a strong concrete. The increasing demands of the aggregates for the usage in construction, lead to the decreasing of natural aggregate. On the other hand, Malaysia was the largest producer of world palm oil and also creates tonnes of waste product, especially palm oil clinker (POC). POC were created in the boiler when the husk fiber and shell of palm oil are burned to generate energy for the refineries. The POC form was like a porous stones which is grey in colour. It's also were flaky, irregular shaped and the broken edge were rough and spiky. Meanwhile, the practise of abundantly available materials to replace normal aggregates in concrete for structural purposes would prove to be economical. Laterite is a ferruginous, vesicular, unstratified and porous material with yellow ochre's due to the presence of high iron content. The main objectives for this study are to determine the compressive strength and workability of concrete using fine palm oil clinker (FPOC) and fine laterite (FL) as artificial fine aggregate. For the purpose of this study, four type's samples were prepared with constant water/cement ratio as 0.51 and 0%, 100% FPOC, 50% FPOC and 25% FPOC with 25% FL as fine aggregate replacement by weight of total fine aggregate. The tests that were conducted are slump test, compacting factor test, vebe test and compression test at curing age of 7, 14 and 28 days. The outcome of this study shows that the replacing of artificial fine aggregates has increases the strength and workability of the concrete. |
