Foam concrete and production process thereof

Abstract

The invention relates to a foam concrete and a production process thereof. The production method comprises the following steps: adding acetylene gas slag and manganese ore tail powder into cement, wherein the weight and ratio of the acetylene gas slag are the same as those of the manganese ore tail powder; combining SiO2 in the manganese ore tail powder with calcium ion silico-calcium in the acetylene gas slag by using an additive, thereby improving the strength of the foam concrete; and simultaneously, adding the manganese ore tail powder with the fineness above 400-mesh fineness, thus the cement usage amount is reduced by above 25% and the strength and volume weight remain unchanged. By using the production method, the production cost is reduced, and the economic benefits of an enterprise are increased.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a foam concrete and a production process thereof. Background technique [0002] Foamed concrete is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then go through the pumping system of the foaming machine for cast-in-place construction or mold molding. A new type of lightweight thermal insulation material containing a large number of closed pores formed by curing. Scholars at home and abroad have done a lot of research and development on it, making it widely used in wall materials. At present, foam concrete blocks have been widely used in my country, such as cast-in-place walls, foundation groove filling, and roof insulation. During the application process, it is found that there are still some defects, such as low strength, cracking, water absorption, etc. Now, the national stan...

Problems solved by technology

Now, the national standards have standardized various technical performance indicators and formulated corresponding technical regulations. According to the standard B09 A5.0 foam concrete blocks, the amount of cement required is generally more than 60% by weight. There are defects such as high cost, the activity of fly ash is not easy to be activated, and it needs to be pressurized and steamed to meet the standard requirements. Therefore, to further expand its application field, it is necessary to improve the blowing agent, mixing ratio, process flow, equipment, etc. do further research
