Abstract

The residue of plastic mixture pyrolysis can be used for making paving blocks. Fibers in plastics can be used as an adhesive against other materials and can increase the strength of paving blocks. Palm oil bottom ash (POBA) was added to replace the role of cement, which has the same content as cement, i.e silica (Si). The purpose of this study was to see the effect of palm oil bottom ash and sand added on the residue of plastic mixture pyrolysis (i.e. PS/LDPE/PP) on the quality of paving blocks. The paving block as test object was made by combining two materials. The residue of plastic mixture pyrolysis and LDPE plastic melt were mixed with a mass ratio of 70:30% referred to as material I. Furthermore, palm oil bottom ash and sand were mixed with mass ratio of 100, 80, 60, 40, 20% referred to as material II. The ratio of ingredients I and II used were 1: 1. Testing of the quality of paving blocks includes a compressive strength test and a water absorption test. The test results showed that the ratio of PS/LDPE/PP mixture (50:25:25) had the compressive strength of 104.1 kg/cm2 or 102.08 MPa and the water absorption of 2.4% at ratio of palm oil bottom ash and sand at 80:20%. The addition of palm oil bottom ash can reduce the compressive strength of paving block. The LDPE content in residue can effect water absorption because its chemical structure properties. Therefore, a reduction in the amount of LDPE residue is needed to obtain optimal water absorption values in paving blocks along with the addition of palm oil bottom ash. Based on this compressive strength in this study and SNI 03-0691- 1996, these paving blocks can be used for gardens.
