Problems solved by technology

[0003] Graphene, as a highly 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 properties into building materials.

Embodiment

[0025] Mix 10 g of graphene oxide, 300 g of sodium silicate, 300 g of potassium bisulfate together, and add 390 g of water. The resulting slurry is denoted as sample A.

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

[0027] Take 1 kg of water and record it as Control C.

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

[0029] Absolute dry strength (MPa) Sample A Sample B Control C Concrete Batch 1 A3.5 A3.0 A2.0 Concrete Batch 2 A3.0 A3.0 A2.5 Concrete Batch 3 A3.0 A3.0 A2.0 Concrete batch 4 A3.0 A3.0 A2.5

Abstract

The invention discloses a graphene slurry, which comprises the following mass fraction components: 0.1%-5% of graphene oxide; 20%-35% of silicate derivatives; 30%-40% of acid salt; and the rest is water. The invention also discloses a graphene aerated concrete, which has low dry density, high strength and low thermal conductivity.

Description

Technical field [0001] The present invention belongs to the field of concrete material technology, particularly relates to a graphene slurry and a graphene aerated concrete. Background [0002] Aerated concrete has the characteristics of high strength, light weight, thermal insulation and heat insulation, and is widely used in China. This has led to the tireless pursuit of higher strength, lower density aerated concrete by practitioners. Traditionally increasing the strength of aerated concrete leads to an increase in density while increasing cost. [0003] As a highly anticipated new material, graphene has the characteristics of high strength and light density, but the common element of graphene is powdery, and it is easy to diffuse with air during operation, making it difficult to introduce its excellent characteristics into building materials. [0004] Moreover, because graphene has excellent thermal conductivity, how to introduce graphene substances to foamed concrete without...
