preparation example Construction

[0045] Alternatively, the preparation method is used, and the preparation method specifically includes the steps of: 1) Accurately weigh water, gelation materials, blend and foam concrete waste fine powder, mix, and produce slurry;

[0046] 2) mix the slurry prepared by the blowing agent from step 1) to prepare mixed slurry;

[0047] 3) Pour the mixed slurry through the conveying conduit to be formed.

[0048] In a particular embodiment of the invention, the blend can be a stone powder, a fine aggregate, a steel slag powder, a particulate blast furnace mine flour, a fly ash, a desulfurized gypsum, a desulfurization powder, a variety of metal tail mine powder and composite powder. One or more kinds of or more. Among them, the specific surface area of ​​the blend is preferably 350m. 2 / kg is above to ensure reaction activity; the blending material is preferably used in two or more combinations to exhibit the advantages of different blends, and minimize certain shortcomings of a sin...

Abstract

The invention provides foam concrete, and belongs to the technical field of foam concrete. The foam concrete is prepared from the following components in percentage by mass: 5 to 45 percent of SiO2, 20 to 55 percent of CaO, 1 to 10 percent of MgO, 0 to 20 percent of Fe2O3, 0 to 15 percent of Al2O3 and 0 to 5 percent of MnO. According to the invention, the cracking defect and hydrophobicity of the foam concrete are improved at the same time.

Description

Technical field [0001] The present invention belongs to the technical field of foam concrete, particularly relates to a foamed concrete. Background technique [0002] Foam concrete is introduced in an appropriate amount of fine bubbles or cement mortar grout, porous concrete by stirring an internal gas bubbles dispersed uniformly formed and then hardened by pouring containing a large amount of pores. Our study of the history of foam concrete short, but through continuous exploration and efforts of researchers and enterprises, foam concrete in our country has been relatively rapid development. [0003] In recent years, the rapid development of my country's industrial accompanied by a large number of solid waste generated, poses a serious threat for the survival of the human environment, to achieve efficient utilization of industrial solid waste caused widespread concern in the community. Industrial solid waste is produced in the human production, processing and consumption process...
