Self-Sensing Concrete Using Functional Fillers for Structural Health Monitoring

Abstract

The self-sensing concrete is fabricated by adding functional fillers into conventional concrete. In the present investigation, the concrete of M30 grade with 53 grade ordinary Portland cement was designed using IS 13920 codes. Two types of functional fillers such as CRIMPED steel fibers (0.5% and 2%) and Graphite powder (0.5% and 2%) were added in different percentages to make various proportions on concrete in order to study their electrical resistivity property. Conventional cubes and SSC cubes are cast to examine their workability as their fresh property, strength and resistivity as their hardened property. The work is focused on a test set up of four probe method, concrete strength properties, and corresponding sensing properties by adjusting a frequency of 4 volts. The work has also relied on the determination of highly reliable sensing concrete
