preparation example Construction

[0046] The preparation method of foam concrete among the present invention, see figure 1 , including the following steps:

[0047] a. Weighing water: Weigh 10-20 parts of water and divide it into two parts of equal mass;

[0048] b. Initial mixing: Weigh 10-20 parts of Portland cement and 1-2 parts of surfactant and place them in a mixer, take part of the water in a and pour them into the mixer, and mix them at 25±5°C, 300 Stir under the condition of -350r / min until evenly mixed to obtain the initial mixture;

[0049] c. Foaming: Take another part of the water in a and pour it into the transfer bucket, add 2-8 parts of protein foaming agent into the transfer bucket, and stir it under the conditions of 25±5°C and 300-350r / min until The protein foaming agent foams completely;

[0050] d. Adding foam: Pour the foaming solution in c into the mixer in b, and stir under the conditions of 25±5°C and 300-350r / min until the foam is evenly dispersed in the initial mixture to obtain a...

Abstract

The invention discloses foam concrete, a preparation method of the foam concrete, and a building wallboard built by using the foam concrete, and relates to the technical field of building walls. The invention solves the problem that the lifting effect of heat preservation performance of existing foam concrete is poor. The technical key points are as follows that the foam concrete comprises the following components in parts by weight: 10-20 parts of Portland cement, 10-20 parts of water, 1-2 parts of a surfactant, 2-8 parts of a protein foaming agent, and 1-5 parts of a building adhesive and other processing aids, and the foam concrete is prepared by the following steps: weighing water, carrying out primary mixing, carrying out foaming, adding foam, and carrying out final mixing. The foam concrete provided by the invention has good heat-preservation performance and mechanical performance.

Description

technical field [0001] The invention relates to the technical field of building walls, in particular to a foam concrete, a preparation method thereof and a building wall board made of the concrete. Background technique [0002] With the continuous rapid development of my country's economy and relatively high energy consumption intensity, the energy crisis is imminent. Therefore, we must attach great importance to energy conservation and emission reduction. Building energy conservation is a key area of ​​energy conservation and emission reduction in my country. In recent years, with the drive of building energy-saving policies and the continuous progress of science and technology, building energy-saving technology has developed rapidly. [0003] Foamed concrete stands out among many thermal insulation materials due to its advantages of fire prevention, light weight, thermal insulation, and heat insulation. Foam concrete is to fully foam the foaming agent by mechanical means,...
