Description
Technical field
The present invention relates to concrete material field, be specifically related to a kind of graphene conductive concrete.
Background technology
In normal concrete, add conductive material, such as carbon fiber, steel fibre, slag, graphite etc., be greatly improved it and lead
Electrically.In correlation technique, conducting concrete is primarily present the deficiency of the following aspects:
(1) performance requirement of both can not taking into account mechanics and conducting electricity, such as, mixes graphite, Ke Yizeng in concrete
Add the electric conductivity of concrete, but due to sliding easy between graphite granule, therefore the intensity of electrically conductive graphite concrete is the most not
High, it is difficult to meet the force request in engineering；
(2) endurance issues of electric conductivity, such as, mixing of steel fiber or slag in concrete, can increase mixed
The electric conductivity of solidifying soil, but in concrete, a steel fibre or slag are still difficult to avoid that the problem of corrosion, when steel steel fibre or
After person's slag corrosion, will there is the biggest change in the electric conductivity of its concrete.
Summary of the invention
For the problems referred to above, the present invention provides a kind of good conductivity, mechanical strength height, resistivity stable and good endurance
Graphene conductive concrete, solves the conducting concrete in correlation technique and can not take into account performance requirement of both mechanics and conduction
And the problem of poor durability.
The purpose of the present invention realizes by the following technical solutions:
A kind of graphene conductive concrete, including portland cement and sand, is characterized in that, adds Graphene as conductive phase
Constitute graphene conductive concrete, each composition relative to the percentage ratio of portland cement and sand gross mass is: Graphene 0.05～
3, graphene dispersion agent 0.5～6, cement water reducing agent 0～0.75.
Wherein, described Graphene is few layer of graphene oxide powder, and the parameter of Graphene is: purity is more than 95wt%, thick
Degree scope is 1.0～1.77nm, and lamella diameter range is 10～50um, and number of plies scope is 1～5, specific surface area be 360～
450m2/g。
Preferably, described graphene dispersion agent is aqueous dispersion.
Preferably, the preparation technology of described graphene conductive concrete is: first mixed with graphene dispersion agent by Graphene
Getting togather, add cement, sand, water reducer and water stirring, batch mix adds mould molding the most afterwards, imbeds rustless steel simultaneously
Screen electrode, and carry out the normal demoulding, maintenance.
The invention have the benefit that
1, utilize the electron transition between graphene sheet layer to form the interior connection without wire of conducting concrete body, use relatively
Few volume, just can obtain good conductivity, and mechanical strength is high, resistivity is stable and the conducting concrete of good endurance；
The resistivity of the concrete after 2, graphene-doped only has 8～10 Ω m, substantially reduces the resistivity of concrete；
3, Graphene physical characteristic is stable, and good endurance will not occur corrosion, and the intensity of Graphene at inside concrete
Height, a small amount of volume i.e. can be greatly improved the intensity of concrete；
4, it is easy to make, is widely used, it is possible to apply in fields such as electric heating ground, floor, deicing or snow meltings.
Detailed description of the invention
The invention will be further described with the following Examples.
The graphene conductive concrete of the present embodiment, including portland cement and sand, and adds Graphene as conductive phase
Constitute graphene conductive concrete, each composition relative to the percentage ratio of portland cement and sand gross mass is: Graphene 0.05～
3, graphene dispersion agent 0.5～6, cement water reducing agent 0～0.75.
Wherein, described Graphene is few layer of graphene oxide powder, and the parameter of Graphene is: purity is more than 95wt%, thick
Degree scope is 1.0～1.77nm, and lamella diameter range is 10～50um, and number of plies scope is 1～5, specific surface area be 360～
450m2/g。

See table 1, the raw material of graphene conductive concrete and proportioning thereof and 28 days resistivity the most corresponding of maintenance
As shown in table 1 with comprcssive strength, wherein the match ratio of Graphene, graphene dispersion agent and cement water reducing agent with its account for cement with
The percentage ratio of sand gross weight represents.
As shown in Table 1: along with the increase of Graphene volume, its electric conductivity is the best.When volume reaches more than 2%, then
Increase Graphene little to resistivity effects.The comprcssive strength of graphene-doped rear concrete has a certain degree of increase, and with
The increase of Graphene volume and increase.
