KHARCOAL conductive cement is a cement-based composite that contains a certain amount of electronically conductive components to attain stable and relatively high conductivity, the aggregates normally used in concrete was largely replaced by a variety of carbon-based materials to achieve electrical conductivity and it is the ideal conductive material to use in areas of poor conductivity, such as rocky ground mountain tops and sandy soil and it dramatically reduces earth resistance and impedance measurements.

KHARCOAL conductive cement is used in the system of protection against lightning and its multifunctional cement, the conductivity is attractive for electrical grounding , lightning protection ,resistance heating (i.e in de-icing and building heating ,static charge dissipation, electromagnetic interference shielding, thermoelectric energy generation and for overlays (electrical contacts) used in the cathodic protection of steel reinforcing bars (rebars ) in concrete.

KHARCOAL conductive cement is manufactured by PT. Kharisma Network System (Kharnets) in Indonesia. Kharnets is an indigenous Indonesian company that has been active in the field of Information Technology since 1989. The services provided range Network Integrator, Data Development center to leasing of IT equipment. Since 2014 Kharnets began to explore the world of industry with a focus on Carbon industry. The first product is KHARCOAL Conductive Cement. KHARCOAL is the first conductive cement manufactured by an indigenous Indonesian company in Southeast Asia.
