preparation example Construction

[0056] In the present invention, there is no special limitation on the preparation method of the regenerated water-resistant putty powder, which can be prepared by the preparation method of the composition well-known to those skilled in the art.

[0057] The present invention also provides the application method of the regenerated water-resistant putty powder described in the above technical solution, comprising the following steps:

[0058] Portland cement, waste aerated concrete powder, lime calcium powder, double fly powder, talcum powder, hydroxypropyl methylcellulose, dispersible latex powder, magnesium aluminum silicate Al 2 MgO 8 Si 2 Mix with dry powder polycarboxylate superplasticizer to obtain the regenerated water-resistant putty powder;

[0059] After the regenerated water-resistant putty powder is mixed with water, construction work is carried out.

[0060] In the present invention, the water is preferably tap water or drinking water.

[0061] In the present i...

Abstract

The invention provides regenerated waterproof putty powder and an application method thereof, which belong to the technical field of building materials. The regenerated waterproof putty powder is prepared from the following components in parts by weight: 220 to 350 parts of Portland cement, 400 to 680 parts of waste aerated concrete micro powder, 50 to 150 parts of ash calcium powder, 50 to 150 parts of heavy calcium carbonate powder, 50 to 120 parts of talcum powder, 2 to 7 parts of hydroxypropyl methyl cellulose, 3 to 8 parts of dispersible latex powder, 3 to 7 parts of magnesium aluminum silicate and 2 to 8 parts of dry powder polycarboxylate superplasticizer. Waste aerated concrete micro powder is used as a main filler, heavy calcium carbonate powder and talcum powder are used as secondary fillers, white cement and ash calcium powder are used as main film-forming substances, hydroxypropyl methyl cellulose, dispersible latex powder, magnesium aluminum silicate and a dry powder polycarboxylate superplasticizer are used as functional aids, and the putty powder has the characteristics of good crack resistance, high bonding strength, favorable water resistance and favorable decorative effects.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a recycled water-resistant putty powder and an application method thereof. Background technique [0002] Aerated concrete blocks are widely used in modern buildings. With their light weight and good thermal insulation effect, they have become one of the important building materials for vigorously promoting the reform of new wall materials in my country. However, after the aerated concrete blocks have reached the end of their service life or the demolition of old houses, a large number of discarded aerated concrete blocks have been produced. The traditional method is to simply backfill and stack them, which not only takes up a lot of land resources, but also It has caused serious pollution to soil and water resources. In addition, the compressive and flexural strength of the aerated concrete block itself is low, and it is easy to be damaged during the production proces...
