Study on amplitude reduction factor of fly ash infilled barrier using vibration sensor

Abstract

Vibrations are phenomenon caused due to cyclic motion caused by certain amplitude and frequency. The ground borne vibrations hinder the building stability and durability. In the present study, the impact of vibrations is reduced with fly ash Infilled barrier. Different soils samples are collected and density is determined using standard compaction test. Density and vibration waves are inversely proportional to each other, that is higher the density of soils lower the propagation of vibration waves and vice versa. After the determination of density, the soils are tested by using vibration sensor in two cases. One is without placing fly ash barrier and the other is by placing fly ash barrier. The output is monitored in the Arduino software and amplitude rection factor and frequency reduction ratio are determined to identify the efficiency of fly ash barrier.
