Karakteristik Struktur Dan Fungsional Aspal Komposit dengan Perbandingan 85%:15%

Synthesis and characterization of rice husk asphalt silica composites was carried out with a ratio 85%: 15%. Silica synthesis from by the sol-gel method. The materials used in this study were husks, asphalt, distilled water, gasoline, NaOH HNO3. Then according to comparison is set at 110oC. This aims look structural characteristics, functionality physical properties, namely water content thickness development sample. Based on research that has been done, it can be concluded results XRD samples have amorphous carbon structures, then based FTIR shows -OH (hydroxil) functional groups occur wave number 3524 cm-1, hydroxide metal Si-OH (silanol) oxidized into Si - O are formed numbers 1084 810 cm-1 462 formation C-H C=O function group occurs 2923 2361 cm-1. test properties 7.642% change 4.783%.
