A kind of chemically foamed silt light soil and its production method

Abstract

The invention discloses a chemically foamed silt light soil and a production method thereof. Added components are sequentially added to a uniformly stirred high-moisture-content solidified soil slurry, and the chemically foamed silt light soil is obtained after stirring, blowing and curing. , the high water content solidified soil mud is obtained by mixing 90~150 parts of inorganic composite binder, 800~1000 parts of high water content mud and external components; 0-5 parts, 1-4.5 parts of plasticizing component, 0.05-0.1 part of hydrophobic component and 4-10 parts of foaming component. The invention adopts chemical foaming to prepare silt light soil, and the foaming component is inorganic material, which is scientific and environment-friendly, does not require dilution and high-pressure treatment, and has low dosage. In actual construction, the self-flowing property of silt light soil mud is fully utilized, which can be filled into small gaps and holes, and the pouring construction efficiency is high, and the integrity of the board is strong. The silt light soil produced has the advantages of small bulk density, high strength, small volume shrinkage, high silt utilization rate, good self-compacting property, strong water stability, and outstanding thermal insulation performance.

Description

A kind of chemical foamed silt light soil and production method thereof Technical field: The invention belongs to the application technology field of novel building materials, be specially a kind of chemical foaming mud light soil and production method thereof Law. Background technique: [0002] In order to meet the construction needs, under the premise of ensuring structural safety, engineering construction is developing towards lightweight and economical. The silt light soil is a pore structure formed inside the silt light soil by physical or chemical means. This pore structure can It can be light solid particles (EPS particles) or some kind of gas (air, oxygen, hydrogen, etc.). It is because of this porosity The existence of silt light soil makes the silt light soil have better lightness (the density is lower than that of water); at the same time, the silt light soil also has self-compacting, Severity and strength adjustability, shock absorption and noise reducti...

AI Technical Summary

Problems solved by technology

[0007] It can be seen from the above representative patents that the silt light soil prepared by the existing physical foaming method mostly uses foaming components and water diluted in advance according to a certain ratio, and then foamed under high pressure. not only need auxiliary mechanical equipment (foaming machine), but also need to be prepared under high pressure; and after the foaming foam is prepared, the storage time is short, and there will be certain defoaming and bleeding, which is different from the slurry When mixing and stirring, the consumption of foam is increased; more importantly, because of the instability of the foam, it is necessary to add foam stabilizing components, and the addition of foam foam is relatively high, generally more than 70% of the volume of high water content mud
