In this paper, we present the vibration performance of lightweight concrete coated biopolymer based on used cooking oil. The composition of material preparation was involved in two categories: (a) fabrication of lightweight concrete by different percentages of rubber aggregate with a ratio from 55%, 60%, 65% and 70% weight by weight, (b) the different proportion of titanium dioxide as additive for biopolymer used cooking oil coating in the ratio of 0.5, 1.0, 1.5, 2.0 and 2.5 by weight with the thicknesses of coating is about 0.30 ± 0.05 mm. The composition of lightweight concrete and surface coating was observed by scanning electron microscope (SEM) image to inspect the effect undercut edge and adhesion on layer coated on lightweight concrete. The results obtained by higher ratio particles sizes of rubber aggregate, which is 70% can reduced more mechanical vibration of lightweight concrete. It was observed that the proportion up to 2.0 by weight titanium dioxide of biopolymer used cooking oil offer some possibility to reduce the characterization of vibration on lightweight concrete in phase with a high frequency of 100 Hz operate at amplitudes is about 0.000174 Grms for input (A1) while 0.000111 Grms for output (A2). In comparison of an uncoated lightweight concrete, the vibration amplitude is higher exceeding 0.002130 Grms for input (A1) and 0.000468 Grms for output (A2). © 2006-2017 Asian Research Publishing Network (ARPN).
