Embodiment

[0021] The embodiment of the present invention adopts the following typical material mix ratio, and the corresponding stainless steel electrode form and arrangement:

[0022]

[0023] (Note: sheet-left and right means that the stainless steel sheet is arranged as electrodes on the left and right sides of the concrete, that is, the direction of the stainless steel sheet perpendicular to the ground, and net 1-up and down means that the stainless steel wire mesh is arranged as an electrode on both sides of the concrete (that is, the direction parallel to the ground ), the diameter of the stainless steel wire is 2mm, the spacing is 25mm, the net 2-up and down means that the stainless steel wire mesh is arranged as electrodes on the upper and lower sides of the concrete, the diameter of the stainless steel wire is 2mm, and the spacing is 15mm).

[0024] For materials used in the table:

[0025] The cement used is ordinary Portland cement, grade 42.5;

[0026] The sand used is n...

Abstract

The invention discloses a form and arrangement of electrodes comprising conductive concrete, and belongs to the technical field of concrete. The form and the arrangement can be widely applied to construction projects of bridge decks, airport runways and the like. The form and the arrangement are characterized in that stainless steel screens are used as the electrodes and are arranged in upper and lower sides, which are parallel to the ground, of the concrete. The form and the arrangement of the electrodes have the advantages that the electrodes can be in sufficient contact with the concrete and are prevented from dropping; electric potential difference between two legs of a pedestrian on the carbon fiber reinforced conductive concrete is eliminated, and the safety of the pedestrian is guaranteed; the constraint of 36V safety voltage on access voltage at ends of the electrodes can be broken through, the access voltage is increased, and accordingly the deicing efficiency is improved; and excessive dependence on the resistivity of the carbon fiber reinforced conductive concrete is prevented, and large carbon fiber reinforced conductive concrete plates can be manufactured and constructed easily during actual project construction.

Description

technical field [0001] The invention relates to an electrode form and arrangement of carbon fiber conductive concrete, which is especially suitable for construction projects such as bridge decks and airport runways, and belongs to the technical field of concrete. technical background [0002] Snow and ice on roads have a great impact on the national economy and people's lives, and also constitute an important hidden danger to traffic safety. Therefore, it is of great practical significance to study how to melt snow and ice. There are many ways to melt snow and ice, which can be divided into two categories, namely, the elimination method and the melting method. The elimination method includes manual elimination method and mechanical elimination method, which need to consume a lot of manpower, material resources and financial resources, and the efficiency is low, and the traffic cannot be restored in time. The melting method includes chemical melting method and thermal meltin...
