Problems solved by technology

[0002] my country's solid waste production is huge and has been increasing year after year. With the growth of solid waste, a number of enterprises engaged in solid waste treatment have been spawned. Most of the enterprises have relatively single solid waste treatment technology and even weak technical force, resulting in solid waste treatment. In the process of secondary pollution, land occupation or the economic benefits of solid waste treatment are not obvious
At present, the treatment of solid waste is still dumping, burying or simple sorting of solid waste, and using effective components to produce single products with low value, such as brick making, mineral powder, road construction utilization, etc.
[0003] It can be seen that the current existing technology has the following problems in the recycling of solid waste: 1. The selection of types of solid waste is relatively narrow, and only part of the solid waste is used
2. The technology for solid waste treatment is weak and single, failing to maximize the utilization rate of solid waste resources, and the treatment of solid waste is not thorough, resulting in secondary solid waste pollution; 3. The products produced by using solid waste are traditional Products with low market competitiveness

Embodiment 1

[0034] Embodiment 1. Using solid waste to prepare steam-free concrete

[0035] 1. Solid waste processing to prepare functional materials

[0036] (1) Pretreatment of solid waste: After collecting quarry debris, tailings, tunnel slag, construction waste, etc., they are broken up and sorted into fine particles and massive particles. Specifically, the first is the sorting of color, such as sorting the broken particles of red bricks separately as raw materials for clinker production; Waste materials such as soil contained in the clinker are directly used as raw materials for the production of clinker; ②25mm-100mm blocky particles enter the production system to produce coarse and fine aggregates; ③>100mm particles are returned again for breaking up and sorting again.

[0037] (2) Aggregate production: the massive particles in step (1) are made into coarse and fine aggregates (replacing stones and Machine-made sand); particles with a particle size between 4.75-31.5 mm can be used ...

Embodiment 2

[0069] Embodiment 2. Using solid waste to prepare self-compacting concrete

[0070] 1. Solid waste processing to prepare functional materials

[0071] The processing of solid waste is the same as in Example 1.

[0072] 2. Preparation of self-compacting concrete

[0073] The self-compacting concrete prepared by the inventive method is compared with the existing self-compacting concrete effect as follows:

[0074] The formula of the composite cementitious material of the present invention: 30% of clinker, 10% of red mud, 10% of burnt coal gangue, 40% of stone powder, 10% of gypsum, and 1.5% of powder activator.

[0075] The clinker comes from the preparation of the aforementioned step (3), and the stone powder comes from the collection of the coarse and fine aggregates in the aforementioned step (2).

[0076] In the self-compacting concrete raw material of the present invention, the fine aggregate prepared in step (2) is used to replace machine-made sand, and the coarse aggre...

Embodiment 3

[0081] Example 3: Using solid waste to prepare self-leveling mortar

[0082] 1. Solid waste processing to prepare functional materials

[0083] The processing of solid waste is the same as in Example 1.

[0084] 2. Preparation of self-leveling mortar

[0085] The self-leveling mortar prepared by the method of the present invention is compared with the existing self-leveling mortar effect as follows:

[0086] The formula of the composite cementitious material of the present invention: 10% of clinker, 20% of burnt coal gangue, 20% of red mud, 40% of stone powder, 10% of gypsum, and 1.5% of activator.

[0087] In the self-leveling mortar raw material of the present invention, the fine aggregate prepared in step (2) is used to replace machine-made sand.

[0088] The DM10 self-leveling mortar prepared by the method of the present invention is compared with the existing ones, and the results are shown in Table 5:

Abstract

The invention provides a method for producing a functional material by solid waste as well as application. Various kinds of solid waste are recycled, and are scattered and sorted to select block granules of 25 to 100 mm, and crude aggregate and fine aggregate are prepared by an aggregate production system; and the produced stone powder is collected for later use. After the crude aggregate and thefine aggregate which are prepared from the sorted fine granules and the blocky granules are ground and calcined to prepare cement clinker. The cement clinker and the stone powder are used for preparing a cementing material. A composite admixture, the crude aggregate, the fine aggregate, the cement and water are used for preparing autoclaving-free concrete, self-compacting concrete, self-leveling mortar and the like. By the method, the solid waste is completely utilized and secondary solid waste pollution is avoided. By the method, components derived from the solid waste are used for producinga product capable of replacing the traditional product, the cost-reducing and effect-improving effects are exerted in the application fields of the product, and the energy-saving and environment-friendly industry orientation is met.
