Example Embodiment

[0034] Example 1: Preparation of non-steam curing concrete using solid waste

[0035] 1. Solid waste processing and preparation of functional materials

[0036] (1) Pretreatment of solid waste: After collecting quarry debris, tailings, tunnel slag, construction waste, etc., it is broken up and sorted into fine particles and massive particles. Specifically, the first is color sorting. For example, the red brick broken particles are separately sorted out as raw materials for the production of clinker; the rest are broken up and sorted into fine particles ① 100mm, return again, and be broken up and sorted again.

[0037] (2) Aggregate production: the block particles in step (1) are made into coarse and fine aggregates (instead of stones and aggregates) using an aggregate production system (for example, application number 201610284827.9, an integrated production system for artificial sand and gravel aggregates) Machine-made sand); particles with a particle size of 4.75-31.5mm instead of...

[0069] Example 2: Using solid waste to prepare self-compacting concrete

[0070] 1. Solid waste processing and preparation of functional materials

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

[0072] 2. Preparation of self-compacting concrete

[0073] The effect comparison between the self-compacting concrete prepared by the method of the present invention and the existing self-compacting concrete is as follows:

[0074] The composite cementing material formula of the present invention: 30% clinker, 10% red mud, 10% coal gangue, 40% stone powder, 10% gypsum, and 1.5% 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 aggregate production process 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 instead of machine-made sand, and the coarse aggreg...

[0081] Example 3: Preparation of self-leveling mortar using solid waste

[0082] 1. Solid waste processing and preparation of functional materials

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

[0084] 2. Preparation of self-leveling mortar

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

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

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

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a method and application of using solid waste to produce functional materials. Background technique [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 dumped, buried or simply sorted, and the effective components are used to produce single products with low value, such as brick making, mineral powder, road construction and so on. [0003] It can be seen that the current existing technology has the followin...
