Pembuatan dan Karakterisasi Bata Konstruksi dengan Memanfaatkan Limbah Sludge Pertamina Pangkalan Susu

Abstract

The material of oil sludge in this research is the waste from PT. Pertamina Pangkalan Susu – Kab. Langkat. Oil sludge is a solid kind waste material from the side effect of oil exploration. This waste includes solid waste that has been dried and shaped lumps (oil sludge). The phisical chracteristic of the paving block sample that studied is density and water absorbtion, and mechanical characteristc is hardness, compressive strength and impact strength. The result of this research shows get that paving block can be made from cement as main binder and oil sludge as main aggregates. The weight composition ratio of cement and aggregates (sand and oil sludge) is 1:4. From the comparison of the composition, we get the result porousity 6.2 – 21.6 %, density 2,29 – 2,45 gr/cm3 , water absobtion 2,94 – 4,44%, hardness 101 - 119,33 HB, compressive strength 14,48 – 19,48 MPa and impact strength (1.79 – 2.52)x104 J/m2 . The best of each samples is the composition 80% oil sludge.
