Embodiment Construction

[0007] In 100 parts of the main slurry composed of fly ash and lime mixed with water, according to the mass ratio, add 10 parts of volcanic tuff powder and 10 parts of steel slag powder as reinforcing agents, and then add 1 part of polyvinyl formal and carboxymethyl Base cellulose 0.5 part as a thickener, then add 0.1 part of calcium stearate and 0.1 part of a mixture of triethanolamine oleate as a foam stabilizer, after fully stirring, add 3 parts of 5% sodium carbonate aqueous solution to the slurry As a foaming agent, add 50-60 grams of degreasing aluminum powder as an air-generating agent at the end, put the prepared slurry into the mixer and stir, inject into the mold after stirring, and become foamed calcium silicate concrete wall material after steaming.

[0008] The technical principle of batching of the present invention:

[0009] The volcanic tuff and steel slag added in the ingredients are active, which can increase the strength of calcium silicate concrete. It can ...

Abstract

The invention provides a compounding method of a foamed silicon-calcium concrete wall building block, which comprises the following steps: in 100 parts of main body slurry formed by mixing fly ash, lime and water, based on the mass ratio, adding 10 parts of volcanic tuff powder and 10 parts of steel slag powder serving as filler, adding 1 part of polyvinyl formal and 0.5 part of carboxymethyl cellulose serving as thickener, adding 0.1 part of calcium stearate and 0.1 part of oleic acid-triethanolamine mixture serving as foaming stabilizer, sufficiently stirring, adding 3 parts of 5% sodium carbonate water solution serving as foaming aid into the slurry, and finally adding 50-60g of degreased aluminum powder serving as gas former; and adding the prepared slurry into a stirrer, stirring, performing injection molding, and performing steam curing to obtain the foamed silicon-calcium concrete wall material. The foamed silicon-calcium concrete wall building block prepared by the invention is high in strength and uniform in pore size distribution, and saves cement. The compounding method provided by the invention is suitable for being used as a foamed silicon-calcium concrete wall building block making method.

Description

technical field [0001] The invention proposes a batching method in the field of wall materials in the field of building materials, specifically a batching method for foamed calcium silicate concrete wall blocks. Background technique [0002] At present, foamed calcium silicate concrete wall blocks usually use fly ash and lime as the main materials, and aluminum powder is added to the mixed slurry for foaming, and foamed calcium silicate concrete wall blocks are made through steam curing. In order to increase the strength, cement is added to the main material, and the cost is increased after adding cement. In actual production, washing powder is added to the mixing slurry as a foam stabilizer. Since washing powder is an anionic surfactant, although it can stabilize the foam, it affects the strength and does not promote the sufficient foaming of the aluminum powder. It also has no thickening effect on the slurry, so it is easy to collapse during the production process, affec...
