1. INTRODUCTION

Electrically conductive concrete is an emerging concrete technology.

Conductivity is property of concrete.

Multifunctional material.

Electrically conductive concrete is produced by adding electrically conductive components.

2. ELECTRICALLY CONDUCTIVE CONCRETE

Properties vary with the components.

Cement based composition.

Controlling environmental pollution.

Cost controlling. 1.For electrically conductive concrete. About $250 per snow storm. 2.Fixed Automated Spray Systems. Initial cost of about $600,000.

3. LITERATURE REVIEW Conductive property is the first property.

Resistivity defining its second property.

High conductivity, keeping resistivity as low as possible.

Mechanical strength and durability.

Behaves as a conductor.

3.1 TECHNOLOGY Conventional mixing

techniques.

Aggregates can be largely replaced by carbon or steel fibers.

Achieve conductivity in concrete.

Make a continuous network of conducting path.
