Abstract

The invention provides a compound concrete foaming agent and its preparation method and application. 1.5-2.5 parts of anhydrous sodium carbonate, 3.5-4.5 parts of industrial caustic soda, 3-5 parts of triethanolamine, 0.2-0.5 parts of industrial grade hydrochloric acid, 53.5-55.8 parts of water; the B component is: triethanolamine 0.2- 0.5 parts, 8-10 parts of sodium sulfate, 12-15 parts of sodium nitrite, 10-25 parts of calcium chloride, 54.7-64.5 parts of water. The composite concrete foaming agent of the present invention can not only increase the amount of foaming agent, but also compensate the concrete strength and solidification time; it can not only produce ultra-low-capacity foamed concrete, but also use a large amount of waste residues such as industrial and construction waste , to produce lightweight foamed concrete.

Description

technical field

[0001] The invention belongs to the field of building materials, and relates to a composite concrete foaming agent and its preparation method and application, in particular to a foaming agent that can increase the amount of foaming agent and compensate the strength and solidification time of concrete. It is a composite foaming agent for producing ultra-low-capacity foamed concrete, and a large amount of waste residues such as industrial and construction waste can be used to produce lightweight foamed concrete. Background technique

[0002] To prepare lightweight foamed concrete, it is first necessary to prepare a foaming agent with a large amount of foam and strong foam stabilizing ability. After foaming by mechanical means, it is mixed with concrete and cast into shape. The lightweight foamed (or foamed) concrete produced by the foaming agent is a porous material with a porosity of up to 85% and a thermal conductivity of 0.15-0.21 / (m.k). At present, there a...
