Problems solved by technology

[0003] At present, during the excavation of the foundation, a large amount of waste soil is produced. The remaining soil is difficult to handle due to the large amount of backfill. It is usually piled up or dumped in the adjacent area by the construction unit, which affects the urban drainage system and traffic. How to improve Making good use of these soils becomes a technical problem

Embodiment 1

[0031] According to the mass ratio, 25 parts of clay, 50 parts of cement, 20 parts of microsilica, 1 part of polypropylene fiber, 2 parts of lithium carbonate, and 2 parts of calcium chloride triethanolamine mixed solution are put into a mixer and fully stirred to form a slurry; The foaming agent and water are formulated into a foaming liquid in a ratio of 1:50, and the foaming liquid is foamed; the prepared foam is added according to 50 times the total volume of the solid components and stirred evenly, and the uniform slurry is poured into Molded in the mold, demolded after 1.5 days of curing and cut to the required size. Then place it at room temperature for curing for 28 days to make a lightweight porous concrete block. The lightweight concrete block is measured according to the standard of GB / T11968-1997 "Autoclaved Aerated Concrete Block", and the light weight is about 900kg / m 3 , the strength is about 8MPa, the dry shrinkage value is 0.25mm / m, and the thermal conductivi...

Embodiment 2

[0033] Weigh 15 parts of clay, 30 parts of cement, 10 parts of microsilica fume, 1 part of polypropylene fiber, 1 part of water glass, and 1 part of calcium chloride triethanolamine mixed solution according to the mass ratio, and put them into a mixer to fully stir to form a slurry; The foaming agent and water are formulated into a foaming liquid at a ratio of 1:50, and the foaming liquid is foamed; the prepared foam is added according to 70 times the total volume of the solid component and stirred evenly, and the slurry is poured directly Into the top floor of the building, after curing, it becomes a foam concrete roof insulation board. After testing, it meets the industry standard requirements for light weight, strength and heat transfer coefficient.

Embodiment 3

[0035] Weigh 20 parts of clay, 40 parts of cement, 15 parts of silica fume, 2 parts of polypropylene fiber, 2 parts of water glass, and 2 parts of calcium chloride triethanolamine mixed solution according to the mass ratio, and put them into a mixer and stir them evenly to form a slurry; The foaming agent and water are formulated into a foaming liquid at a ratio of 1:50, and the foaming liquid is foamed; the prepared foam is added according to 60 times the total volume of the solid component and stirred evenly, and the slurry is poured directly Into the building floor heating project, after curing, it becomes the foam concrete floor heating insulation layer. After testing, it meets the industry standard requirements for light weight, strength and heat transfer coefficient.

Abstract

The present invention relates to an air conditioning type foam concrete material and a preparation method thereof. The air conditioning type foam concrete material comprises a solid component and foaming agent foams, wherein the solid component comprises, by mass, 15-25 parts of clay, 30-50 parts of cement, 10-20 parts of micro-silicon powder, 0.5-1 part of fibers, 1-3 parts of an early strength agent, and 1-3 parts of coagulant, the volume of the foaming agent foams is 50-70 times the total volume of the solid component, and the foaming agent foams are prepared by foaming a foaming agent aqueous solution obtained by mixing a foaming agent and water according to a mass ratio of 1:50. Compared with the air conditioning type foam concrete material in the prior art, the air conditioning type foam concrete material of the present invention has the following characteristics that: the clay material is adopted as the aggregate to prepare the foam concrete, and the characteristic that the clay and the concrete have microscopic pores is effectively utilized so as to produce the excellent thermal insulation property, such that the light weight material having effects of excellent thermal insulation and humidity adjustment can be prepared, and can be directly used for the non-load-bearing structure position requiring the thermal insulation effect.

Description

technical field [0001] The invention relates to a foam concrete in the technical field of construction engineering, in particular to an air-conditioning foam concrete prepared from clay materials and its application. Background technique [0002] With the increasingly severe use of resources in the world, building energy conservation has become a new topic and development direction of modern buildings. As the roof insulation layer of the non-load-bearing parts of the building, floor heating projects, cushions and floor insulation layers, people tend to use foam concrete materials. Foamed concrete is a porous lightweight material made of cement and other mixed materials mixed with water and then mixed with foam made of foam agent, and then hardened. Simple and many other advantages. In recent years, foam concrete has developed rapidly, and many patented products have appeared. For example, Chinese patent publication number: CN101973779A, patent name: a preparation process ...
