Embodiment

[0025] 10g graphene oxide, 300g sodium silicate, 300g potassium bisulfate are mixed together, then add 390g water. The obtained slurry is designated as sample A.

[0026] Add 10g of graphene oxide to 1KG of water to disperse, and record it as sample B.

[0027] Take 1KG of water and record it as control C.

[0028] After that, using the common air-entrained concrete production process, before the slurry was stirred, additional sample A, sample B, and control C were added, and then the process was continued to obtain air-entrained concrete. Repeat four times, measure dry density, dry strength, thermal conductivity:

Abstract

The invention discloses graphene slurry which comprises the following components in percentage by mass: 0.1-5% of graphene oxide, 20%-35% of a silicate derivative, 30%-40% of an acid salt and the balance of water. The invention also discloses graphene aerated concrete, and the aerated concrete has low dry density, high strength and low thermal conductivity.

Description

technical field [0001] The invention belongs to the technical field of concrete materials, in particular to a graphene slurry and a graphene aerated concrete. Background technique [0002] Aerated concrete has the characteristics of high strength, light weight, thermal insulation, and is widely used in our country. This has brought about the tireless pursuit of practitioners for higher strength and lower density air-entrained concrete. Traditionally, increasing the strength of air-entrained concrete will increase the density and increase the cost. [0003] Graphene, as a much-anticipated new material, has the characteristics of high strength and light density. However, the common simple substance of graphene is powder, and it is easy to diffuse with the air during operation, making it difficult to introduce its excellent characteristics into building materials. [0004] Moreover, since graphene has excellent thermal conductivity, how to introduce graphene-like substances i...
