Problems solved by technology

Although the strength of the aerated concrete block has been improved, its density is higher than that of ordinary aerated bricks, which increases the self-weight of the building, which requires the modification of the foaming agent used in the aerated bricks. Improve the foaming effect and foam stability to reduce the weight of the aerated brick. At the same time, it is necessary to increase the additional performance of the aerated brick to meet the development needs of the construction industry

Abstract

The invention discloses a high utilization-rate and developed-cell gas-added brick added with steel slag magnetic separation tailings and cement. The brick body slurry is added with graphene oxide modified polycarboxylate water reducer, the dispersibility in the slurry can be improved, the early strength and the later strength and toughness of the slurry are improved, the amount of cement is reduced, and the production cost is further reduced; the aerated brick prepared by the invention is low in cost, waste is utilized, and the gas-added brick is environment-friendly, the strength is improved, and meanwhile the good heat insulation property, the water permeability resistance, the compression resistance and the wear resistance are achieved, and the brick is not easy to break.

Description

technical field [0001] The invention relates to the technical field of autoclaved aerated concrete blocks, in particular to an aerated brick with added steel slag magnetic separation tailings and cement with high utilization rate and well-developed cells. Background technique [0002] Autoclaved aerated concrete blocks have the advantages of light weight, high strength, good durability, and certain thermal insulation effects, and can be better used in load-bearing and non-load-bearing walls of industrial buildings and thermal insulation, and are favored by countries all over the world The general attention of the construction industry has become a building material vigorously promoted and developed in many countries. Its raw materials are mainly fly ash and other chemical wastes, which are mixed with cement and lime to make a slurry, and then combined with pulping, injection molding, curing and other processes to make it. However, in some areas, due to the lack of fly ash o...
