Problems solved by technology

[0008] Comparative document 3 uses the on-site pouring of chemical foaming cement slurry, and is equipped with light steel keels. However, during pouring, the opening end of the light steel keel is not in the same direction as the pouring port, and the foamed cement is in the mold and the light steel keel. The foaming effect will be restricted by the placement of light steel keels, so the foaming effect is limited

Embodiment Construction

[0032] refer to figure 1 The specific examples of the preparation method of the cement foam wall with light steel keel of the present invention will be further described.

[0033] A method for manufacturing a cement foam wall, comprising the steps of:

[0034] Step 1. Evenly arrange the C-shaped or U-shaped light steel keel in the mold, the opening of the mold is in the same direction as the opening of the C-shaped or U-shaped light steel keel, and the height of the mold is higher than The side wall height of C-shaped or U-shaped light steel keel;

[0035] Step 2. Mix water, cement and reinforcing fiber, heat and stir evenly to make cement slurry;

[0036] Step 3. Add a foam stabilizer to the cement slurry, stir evenly and add a foaming agent, stir the newly obtained cement slurry and quickly pour it into a mold with a C-shaped or U-shaped light steel keel placed evenly;

[0037] Step 4. Let the cement slurry poured into the mold stand for foaming, and demould after at leas...

Abstract

The invention discloses a cement foam wall structure, a manufacturing process and a foamed cement paste formula for the wall, which solves the problem of insufficient strength and toughness of the foam cement wall in the prior art, and reduces the need for on-site The key point of the equipment investment is to pour foamed cement slurry evenly in the mold with light steel keels evenly arranged, so that the cement slurry can be chemically foamed in the mold, saving the equipment that only uses physical foaming in the prior art The cost, and the addition of materials such as light steel keel, cement reinforcing agent, and reinforcing fiber, have improved the strength and toughness of the wall.

Description

technical field [0001] The invention belongs to the technical field of exterior walls, more specifically, it relates to a cement foam wall structure and a manufacturing process. Background technique [0002] Foamed cement insulation board is a new type of exterior wall material commonly used to replace traditional organic insulation materials. In the prior art, foamed cement usually has two preparation methods: physical foaming and chemical foaming. The so-called physical foaming means that the foaming agent is fully foamed mechanically through the foaming system of the foaming machine, and the foam is evenly mixed with the cement slurry, and then poured on site or molded through the pumping system of the foaming machine. A new type of lightweight thermal insulation material with a large number of closed pores formed by natural maintenance. It belongs to the bubble-shaped thermal insulation material, which makes the wall light and has thermal insulation performance. However,...
