Embodiment 1

[0040] A method for preparing a lightweight filled cast-in-place wall, comprising the steps of:

[0041] S1, in parts by mass, add 200 parts of cement, 300 parts of stone powder, 300 parts of slag, 10 parts of admixture, and 120 parts of water into a mixer and stir evenly to obtain a mixture;

[0042] S2, after stirring evenly, put the mixture into the mixer truck and transport it to the construction site for pouring;

[0043] S3, according to the working conditions, use the reusable shaped plastic formwork to carry out the assembly and shaping of the process-oriented mold, and reinforce the shaped mold with pins;

[0044] S4, add 0.1 part of foaming agent in parts by mass to the mixture, avoid vibration, after foaming, pour it into the previously established mold through the delivery pump to form. Wherein, foaming agent is sodium lauryl sulfate.

Embodiment 2

[0046] A method for preparing a lightweight filled cast-in-place wall, comprising the steps of:

[0047] S1, in parts by mass, add 200 parts of cement, 500 parts of slag, 12 parts of admixture, 130 parts of water, and 100 parts of fly ash into a mixer and stir evenly to obtain a mixture;

[0048] S2, after stirring evenly, put the mixture into the mixer truck and transport it to the construction site for pouring;

[0049] S3, according to the working conditions, use the reusable shaped plastic formwork to carry out the assembly and shaping of the process-oriented mold, and reinforce the shaped mold with pins;

[0050] S4, adding 0.25 parts of foaming agent in parts by mass to the mixture, avoiding vibration, pouring into the previously erected mold by a delivery pump after foaming to form. Wherein, foaming agent is sodium lauryl sulfate.

Embodiment 3

[0052] A method for preparing a lightweight filled cast-in-place wall, comprising the steps of:

[0053] S1, in parts by mass, add 200 parts of cement, 10 parts of admixture, 200 parts of stone powder, 130 parts of water, 250 parts of slag, and 150 parts of fly ash into a mixer and stir evenly to obtain a mixture;

[0054] S2, after stirring evenly, put the mixture into the mixer truck and transport it to the construction site for pouring;

[0055] S3, according to the working conditions, use the reusable shaped plastic formwork to carry out the assembly and shaping of the process-oriented mold, and reinforce the shaped mold with pins;

[0056] S4, add 0.2 parts of foaming agent by mass to the mixture, avoid vibration, after foaming, pour into the previously established mold by delivery pump to form. Wherein, foaming agent is sodium lauryl sulfate.

Abstract

The invention discloses novel foamed concrete, a foamed concrete prefabricated part and a preparation method of a light filling cast-in-place wall. The invention discloses novel foamed concrete which comprises the following components in parts by weight: 150-350 parts of cement, 150-500 parts of stone powder, 150-500 parts of furnace slag, 50-200 parts of inorganic matter calcium hydroxide, 50-350 parts of fly ash, 150-500 parts of building solid waste, 150-500 parts of pumice particles and stone powder, 150-500 parts of industrial solid waste ore particles and stone powder, 30-150 parts of polyurethane, 100-300 parts of industrial sintered product waste residues (such as clay, shale and calcium stone), 20-50 parts of polyphenyl particles, 0.1-0.4 parts of a foaming agent, 3-12 parts of an additive and 120-200 parts of water. The novel foamed concrete has the characteristics of greenness, environment-friendliness and low production cost.

Description

technical field [0001] The invention relates to the technical field of non-load-bearing lightweight concrete, in particular to a preparation method for novel foamed concrete, foamed concrete prefabricated parts and lightweight filled cast-in-place walls. Background technique [0002] Among them, a large amount of construction solid waste and industrial solid waste are mixed with domestic garbage and construction waste, which has caused adverse effects on the ecological environment. The recycling and treatment of solid waste has always been a difficult problem in the industry, causing serious pollution to the ecological environment. Including calcium hydroxide is a commonly used inorganic material referred to as limestone or raw slaked lime water is widely used in home decoration and other fields. With the progress and development of social home life, updates and iterations are rapid. There are also wastes such as industrial fired product waste residue (such as shale, clay,...
