Problems solved by technology

The process of preparing foamed concrete by this method is easy to destroy the air bubbles produced by the foaming agent and reduce the foam content in the foamed concrete. During construction, it is necessary to take bricks to open holes on the wall, and then fill the holes, support outside the wall, and Maintenance and other process preparations will inevitably produce noise pollution and air pollution, and the process is cumbersome, the workload is heavy, and the practical application is limited

preparation example Construction

[0032] The preparation method of the foamed concrete slurry of the present invention comprises the following steps: uniformly mixing the mixed slurry and the foaming liquid in a drum type mixing device to obtain final product; the main components of the mixed slurry are cement, fly ash and Water, the main components of the foaming liquid are foaming agent, foam stabilizer and water.

[0033] Further preferably, the drum mixing equipment is a horizontal low-speed drum mixing equipment. The rotation axis of the drum of the horizontal low-speed drum mixing equipment is parallel to the ground or a parallel plane. The rotating speed of the drum mixing equipment is 30~120r / min.

[0034] Preferably, the fly ash is at least one of primary fly ash, secondary fly ash and tertiary fly ash.

[0035]The mass ratio of foaming agent, foam stabilizer and water in the foaming liquid is (0.33-0.67):(0.15-0.35):(7.79-35.27).

[0036] The foaming agent is selected from fatty acid glycerides, α...

Embodiment 1

Abstract

The invention belongs to the technical field of building materials, and in particular relates to a foam concrete slurry and a preparation method thereof, a lightweight wallboard and a preparation method thereof. The lightweight wallboard of the present invention is made from foamed concrete slurry, and the foamed concrete slurry is prepared by a preparation method comprising the following steps: uniformly mixing the mixed slurry and foaming liquid in a drum-type mixing device to obtain The main components of the mixed slurry are cement, fly ash and water, and the main components of the foaming liquid are foaming agent, foam stabilizer and water. A large number of closed micropores are distributed in the lightweight wallboard poured by the foam concrete slurry of the present invention, and a skeleton is included, which meets the requirement of both thermal insulation and strength of the wallboard.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a foam concrete slurry and a preparation method thereof, a lightweight wallboard and a preparation method thereof. Background technique [0002] Lightweight wallboard is a new type of building enclosure wall material. It is an energy-saving green building material. It has the characteristics of increasing the use area, reducing the weight of the wallboard, improving the use function, reducing the construction cost, and improving the construction efficiency. Lightweight wall panels are an important part of prefabricated buildings. With the progress of society and the development of building industrialization, higher diversified requirements are put forward for lightweight wall panels. The board body of the lightweight wallboard is a concrete board body, and the foam (foamed) concrete has been widely used in the field of building wall insulation in recent yea...
