Study of Microstructure of Electrically Conductive Silicate Composites with Graphite-Based Fillers

Article Preview

Abstract:

Electrical conductive composite materials are nowadays widely used in many industrial applications include building materials. One of the possible applications is as a resistance probe. Those probes were designed to monitor internal structural changes of building materials built into construction and to predict their durability, over-load, or defects. Mostly used composite materials are silicate or biopolymer-based with carbon-based filler. This article is dedicated to the study of the microstructure of silicate-based electrically conductive composites with graphite-based fillers. The microstructural shape of fillers was chosen concerning preserving as high conductivity as possible. Furthermore, the effect of moisture on the electrically conductive properties of the silicate composite was monitored.
