Evaluation of conductive concrete for anti-static flooring applications

Abstract

Static electricity, exchange of electrons, and retention of charge between any two materials due to contact and separation are affected by the condition of the materials being nonconductive or insulated from ground. Several work environments, such as electronics industry, hospitals, offices, and computer rooms all require electro-static discharge (ESD) mitigation. Carpet Tile, Carpet Broadloom, Vinyl Tile, Vinyl sheet, Epoxy and Rubber are examples of existing flooring systems in the market. However, each system has its advantages and limitations. Conductive concrete is a relatively new material technology developed to achieve high electrical conductivity and high mechanical strength. The conductive concrete material can be an economical alternative for these ESD flooring systems. In this paper, the effectiveness of conductive concrete as an anti-static flooring system was evaluated. The initial results indicated that the proposed conductive concrete flooring and ground system met the acceptance criteria stated by ASTM F150.

“…Conductive concrete has found widespread applications in various fields, including deicing surfaces, providing electromagnetic shielding, establishing efficient grounding systems, creating anti-static flooring, and enabling cathodic protection for reinforced concrete structures. These applications capitalize on the excellent electrical conductivity and other favorable characteristics of conductive concrete, showcasing its immense potential and utility in diverse scenarios [2]- [8].…”
