ORIZA SATIVA, NIM 2210247005, The Utilization of Oil Well Drilling Cutting Cement Waste as an Alternative Filler Material for Brake Pad Composites. Supervised by Putri Nawangsari and Desi Heltina.
This study aims to optimilize the cutting cement waste derived from drilling and well services activities, focusing on its chemical composition using X-ray Fluorescence (XRF), crystal phase and structure analysis with X-Ray Diffraction (XRD), and thermal properties with Simultaneous Thermal Analysis (STA). The research also evaluates the impact of varying cutting cement volume fractions on density, hardness, porosity, and tribological properties
The study begins by measuring the density of cutting cement particles according to ASTM D 2320-98 standards. Subsequently, the composition ratio of cutting cement to BaSO4 is varied based on volume fractions (37:0; 27:10; 17:20; and 7:30) %. The mixing process of the sample bahans is conducted using a chopper mixer for 5 minutes. The powder mixture is then hot compaction using uniaxial hot pressing at a pressure of 5 tons, a temperature of 165 °C for 15 minutes. Postcuring of the samples is carried out at 165 ºC for 10 hours. After postcuring, the samples undergo density testing (ASTM D 2320-98), HR-R hardness testing (ISO 6508), porosity testing (JIS 4418:1996), and tribological testing for friction coefficient and wear, based on SNI 09-0143-1987 standards. The worn surface morphology of the samples is analyzed using SEM observation
Characterization results indicate that cutting cement contains CaO, SiO2, Fe2O3, Al2O3, and MgO compositions with respective percentages of 66,2%, 18,70%, 5,7%, 3,4%, and 2,3 %wt. XRD results show a CaCO3 (calcite) crystal peak of 44 %wt at a 2θ angle of 29,33°. STA analysis results show that the highest weight loss of cutting cement occurs at temperatures ranging from 49,41°C to 398,99°C, amounting to 10,32%, with an absorbed energy of 908,448 J/g. Density test results indicate that the highest average density of 2,41 g/cm3 occurs in samples with a BaSO4 composition of 27% vol and cutting cement of 10% vol, with an average hardness value of 104,72 HRR. The lowest average friction coefficient of 0,457 and the highest wear rate (2,435 x 10-7 cm3/N.m) are observed in samples with a BaSO4: cutting cement composition of 37:0 % vol, while the highest average friction coefficient (0,492) is found in samples with a BaSO4: cutting cement composition of 7:30 % vol. The BaSO4: cutting cement (7:30) % vol composition also shows the highest fading performance at 3,7%, the highest friction coefficient stability at 0,85, the lowest friction coefficient fluctuation at 0,2, the lowest friction coefficient variation at 0,08, and recovery performance at 117,83%. Based on the results of friction coefficient and wear testing according to SNI 09-0143-1987 standards, the sample with a BaSO4: cutting cement ratio of 7:30 % vol has the potential to be used as a non-asbestos brake pad for Class 1A,1B,2, and 3 vehicle classification.
