Title:

CONDUCTIVE CONCRETE COMPOSITION

Document Type and Number:

WIPO Patent Application WO2001072657

Kind Code:

A3

Abstract:

The invention provides conductive concrete suitable for commercial and large-scale production. The conductive concrete uses carbonaceous particles as conductive phase, to achieve concrete with resistivities as low as 2 OMEGA cm and compressive strengths over 30 Mpa (both measured at 28 days).
