Composite electric conductive concrete

Abstract

A composite concrete containing electric conducting cells used for shielding radio interference and electromagnetic wave, grounding unit, lightning protector, electrostatic eliminator, heating floor, expressway, etc is prepared from cement, sand, cobble, carbon material, and metal material. Its advantages are high electric conductivity, strength and stability, low cost and long service life.

Description

[0001] (1) Technical Field: The present invention relates to a multi-functional composite conductive element concrete prepared by using carbonaceous materials and fibrous or chip-like metal materials as conductive materials, and belongs to the technical field of new materials. (2) Background technology: [0002] In recent years, conductive concrete is mainly single-phase conductive elementary concrete, and under economic conditions, most of them cannot meet the requirements of strength and conductivity at the same time. For example, the graphite conductive concrete disclosed in Chinese Patent 00107279.X has very good conductivity, but the strength is greatly reduced due to the excessive amount of graphite. The conductive concrete electric heating device disclosed in Chinese Patent No. 95121612.0 is a very good heating device, which is used in the construction field with low strength requirements. Chinese patent 95121611.2 discloses a conductive concrete that can be used as an elect...

AI Technical Summary

Problems solved by technology

Chinese patent 95121611.2 discloses a conductive concrete that can be used as an electric heating material. Concrete reinforcement fibers are used to strengthen the strength of the concrete, which can have good conductivity and high strength at the same time, but the cost is high

The disadvantage of conductive concrete with steel fibers as the conductive material is poor conductivity
