Embodiment 1

[0047] A steam-free foamed concrete block is prepared by adding water to the following raw materials:

[0048] 600 kg of ceramic polishing waste, 149.4 kg of sand powder, 250 kg of cement, and 0.6 kg of cement foaming agent.

[0049] Its production process is as follows (such as figure 1 shown):

[0050] 1. Take raw materials

[0051] Take 600 kg of ceramic polishing waste. The particle size of ceramic polishing waste is 200-500 mesh. Ceramic polishing waste can be directly extracted from the sedimentation tank in the ceramic tile production process. If it is extracted from the sedimentation tank, 600 kg of ceramic polishing waste In terms of net content, that is, the net content of ceramic polishing waste is 600 kg after removing the water. Ceramic polishing waste can also be obtained from the waste pile. If there are other sundries in the ceramic polishing waste, the sundries should be removed; take 60 ~ 149.4 kg of 200-mesh sand powder, which can be pre-processed into 60...

Embodiment 2-6

[0067] Compared with Example 1, the main difference of Examples 2-6 is that the proportions of each component of the raw materials are different, and other process technical characteristics are the same as Example 1, and the specific raw materials and portions used in Examples 2-6 are as shown in Table 1 below .

Embodiment 7-18

[0069] Compared with Example 1, the main difference of Examples 7-18 is that the raw material is to use stone powder or sand powder and stone powder to replace the sand powder in Example 1, and other technical characteristics are the same as in Example 1, and Examples 7-18 Concretely used raw materials and portions are shown in Table 1 below.

Abstract

The invention discloses a steam-curing-free foam concrete building block, which is prepared by water and the following raw materials in parts by weight: 50-60 parts of ceramic polishing waste, 15-20 parts of sand flour or / and rock flour, 25-30 parts of cement and 0.06-0.2 part of cement foaming agent. The invention further discloses a preparation method of the building block, comprising the steps of taking the above raw materials, preparing a sizing agent, diluting the foaming agent, preparing pulpy foam concrete, molding, demolding, curing and the like. The steam-curing-free foam concrete building block of the invention has the characteristics of light weight and high strength, good heat preservation and thermal insulation performance, good sound insulation and fireproof performance, low elasticity and seismic resistance, fast construction speed and the like. In addition, the invention can turn waste into wealth and protect the environment.

Description

technical field [0001] The invention relates to a wall block and a preparation method thereof, in particular to a steam-free foamed concrete block and a preparation method thereof. Background technique [0002] At present, in the production process of architectural ceramics (mainly flat tiles), three major pollutions are mainly produced: waste water, waste gas and solid waste. Among them, the solid waste is mainly the (fine powder) wet waste produced by the polishing and grinding process in the process of manufacturing ceramic flat tiles, which is called ceramic polishing waste, also referred to as waste porcelain mud. A general-scale ceramic tile factory produces more than 100 tons of polishing waste a day. In the current ceramic industry, dozens of enterprises are often concentrated in one industrial area, and more than one thousand tons of polishing waste are produced every day. Due to the lack of timely treatment and utilization of these wastes, this waste has been con...
