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...
