Abstract

This research was conducted to determine the effect of CaCO3 levels on the formation of superconducting phase BPSCCO - 2212 by calculating the level of purity of the phases formed and looking at the microstructure. The variation of CaCO3 was 0.95, 1.00, 1.05 and 1.10 mole using the wet mixing method. The samples were calcined at 800 ° C for 10 hours, and sintered at 820 ° C for 20 hours. Synthesized samples were characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The XRD’s chacterization results show that the level of purity of the formed phases increases with increasing Ca levels with maximum point at BPSCCO-2212/1.10 mole. The highest volume fraction was 79,06% in the BPSCCO-2212/1.10 sample. While the lowest volume fraction was 72.10% in the BPSCCO-2212/0.95 sample. Meanwhile, the highest degree of orientation was 20.59% at BPSCCO-2212/0.95. The lowest degree of orientation was 8.46% at BPSCCO-2212/1.10. SEM’s chacterization results show of all samples have been oriented altought not perfect yet and have relatively little space between slabs (voids).

Abstract

Synthesis and characterization of silica rice husk blend asphalt was carried out with a mass ratio of 1;0; 1:1,5; 1:1,6 and 1:1,7 respectively. Rice husk was prepared by sol-gel method as a raw material of silica. Asphalt and silica is mixed by using the solid-sate method, which is heated with a temperature of 110 oC for 4 hours. This study was revealed to investigate the effect of the addition of silica from rice husk on microstructure and asphalt structure. SEM results show the morphology of the asphalt surface without addition of silica which transforms elongated folds and after addition of silica shows uncertain granules more likely seems clusters with grain size (1:1,5 = 4,298 ?m, 1:1,6 = 3,103 ?m and 1:1,7 = 5,328 ?m) respectively. The XRD results show asphaltene amorphous phase in the asphalt sample with two peaks at 2?= 18,90? and 2?= 42?. Furthermore, the addition of silica with asphalt able to modify two asphaltene peaks into carbon and silica amorphous peaks.

Abstract

This study was conducted to determine the functional characteristics and physical properties of asphalt due to the addition of silica rice husk. Asphalt penetration 60/70 was combined with silica sourced from extracted rice husks using the sol gel method with 1.5% NaOH solvent and 10% HNO3 solvent. Comparison of asphalt and silica masses is 1: 1.8; 1: 1,9; and 1: 2, then asphalt and silica alloys are heated at 110oC for 4 hours. The results of Fourier Transform Infra-Red (FTIR) analysis showed that the O-H group was formed after the addition of silica. The functional groups seen are functional groups associated with asphalt and silica that is C-H, Si-OH, Si-O-Si, and Si-O. The results of swelling thickness and degradation physical tests (diameter, thickness, and volume) indicate that this material is quite stable. In each addition of silica the increase in increment occurs only slightly. This proves that the interaction between asphalt and silica that occurs physically and does not occur in a chemical reaction.
