Problems solved by technology

However, the overall performance of the masonry materials obtained in this way still needs to be improved, especially the sound insulation performance is average.
Moreover, this method is not closely integrated with the production process of foamed ceramics, and the foamed ceramic waste needs to be processed and transported to the concrete mixing station for processing, which is likely to cause secondary pollution

Embodiment 1

[0034] The foamed ceramic waste used in all the embodiments of the present invention is the waste produced by the applicant (Jinyi Lvneng New Materials) foamed ceramic plate production line, including unqualified waste and cutting and polishing in the production process of foamed ceramics crumbs.

[0035] The foamed ceramic waste is crushed with a crusher, and then the crushed material is screened to obtain granular waste and powdery waste, wherein the particle size of the granular waste is 1mm-30mm, and the particle size of the powdery powder is <1mm .

[0036] Weigh 325 cement, granular waste and powdery waste according to the following mass percentages: 50% of 325 cement, 20% of granular waste, and 30% of powdery waste, add water and mix uniformly to make a slurry.

[0037] Select a foamed ceramic plate with a specification of 2000mm*1000mm*20mm, set a surrounding edge with a height of 60mm around it, then pour the slurry, shake and smooth it, and maintain it in a humid en...

comparative example 1-1

[0039] The slurry is prepared according to the proportioning process in Example 1, and the above slurry is poured into a conventional mold for vibration and compaction to obtain a masonry material product of the desired shape. In this example, we made a plate with a specification of 2000mm*1000mm*80mm, and maintained the plate in a humid environment for at least 15 days to obtain a plate-shaped material that can be used for wall masonry. Its cross-sectional structure is shown in the attached figure 2 As shown, granular foamed ceramic waste 2 is wrapped in concrete 1 . We tested the board, and the air sound insulation is 38dB. In terms of this thickness, the sound insulation performance of the material is average.

Embodiment 2

[0046] Under the condition that the ratio of raw materials is determined, the particle size of granular waste is related to the compressive strength and air insulation volume of masonry materials. We test this. Select the following mass ratio: 325 cement 40%; granular waste 20%, powdery waste 40%.

[0047] 2-1. The particle size of granular waste is 5mm-10mm.

[0048] 2-2. The particle size of granular waste is 10mm-15mm.

[0049] 2-3, The particle size of granular waste is 15mm-20mm.

[0050] 2-4, the particle size of granular waste is 20mm-25mm.

[0051] 2-5, the particle size of granular waste is 25mm-30mm.

[0052] Other processes, such as embodiment 1, are prepared into a masonry material with a thickness of 80mm, and the sound insulation performance of the test is as follows:

[0053] 2-1: The air insulation volume is 47dB.

[0054] 2-2: The air insulation volume is 49dB.

[0055] 2-3: Air insulation volume 50dB.

[0056] 2-4: Air insulation volume is 45dB.

Abstract

The invention relates to the field of waste solid recycling, in particular to a method for producing a masonry material from foamed ceramic waste. The method comprises the following steps that: (1) foamed ceramic waste is recycled, crushed and screened for use, granular waste and powdery waste are obtained through screening, the particle size of the granular waste ranges from 1 mm to 30 mm, and the particle size of the powdery waste is smaller than 1 mm; step 2) the following raw materials in percentage by mass: 15-60% of cement, 5-40% of granular waste and 0-50% of powdery waste are weighed;(3) water is added, and the materials and water are mixed to prepare slurry; and (4) the slurry is molded, the foamed ceramic material is used as a mold during molding, and the molded mold and a slurry cured material are compounded into a whole, so that the masonry material can be obtained. Compared with the prior art, the masonry material obtained through the method has good sound insulation performance.

Description

technical field [0001] The invention relates to the field of recycling waste solids, in particular to a method for producing masonry materials by using foamed ceramic waste. Background technique [0002] Foamed ceramics is a ceramic material with closed pores, which has the characteristics of light weight and heat preservation, and is often used as a wall insulation material. At present, the process of industrialized production of foamed ceramics has become increasingly mature. Adding high-temperature foaming agent to the raw materials for ceramic production, cutting and polishing after high-temperature firing can obtain foamed ceramic plates. Commonly used high-temperature foaming agents include silicon carbide, carbon powder, iron oxide, etc. At present, most of the foaming agents used in industrial production are silicon carbide powder or polishing slag containing silicon carbide. Foamed ceramics will expand rapidly during the sintering process, and problems such as crac...
