preparation example Construction

[0022] The invention relates to a non-burning antique green brick, which can be reused as a resource to reduce environmental pollution and avoid safety accidents such as landslides. The performance indicators of the solid waste non-burning antique green brick meet the standard requirements. The preparation method is simple and convenient.

[0023] The fire-free antique green brick includes a base layer and a surface layer. The base layer contains the following components: residual mud, recycled aggregate and cement; the surface layer contains the following components: white Portland cement, slag powder, recycled fine aggregate, Iron Oxide Black and Iron Oxide Green.

[0024] Wherein, the mass ratio of the components in the base layer of the non-fired antique green brick is as follows: 8-42 parts of residual mud, 52-85 parts of recycled aggregate and 3-20 parts of cement. Preferably, the mass ratio of the components in the base layer of the non-fired antique green brick is as ...

Embodiment 1

[0041]Fully mix 200kg of ordinary cement, 400kg of residual mud, 400kg of recycled coarse aggregate, and 300kg of recycled fine aggregate, add 100kg of water, and continue to stir evenly to obtain a base layer mixture; mix 50kg of White Portland cement, 20kg of slag powder, 10kg of regenerated fine aggregate, 2kg of iron oxide black and 6kg of iron oxide green are thoroughly mixed, add 4kg of water, and continue to stir evenly to obtain a mixture for the surface layer . First put the mixture of the base layer into the mold, put it on the press and press it under the pressure of 30MPa, then spread the mixture of the surface layer on the base layer, put it on the press and press it under the pressure of 30MPa, and finally natural curing for 28 God, the topping is about 12.3mm thick.

[0042] Detect the performance indicators of unfired antique green bricks: test its appearance quality, density, and compressive strength, and the results are shown in Table 1.

Embodiment 2

[0044] Fully mix 120kg of ordinary cement, 200kg of residual mud, 480kg of recycled coarse aggregate, and 40kg of recycled fine aggregate, add 60kg of water, and continue to stir evenly to obtain a base layer mixture; mix 55kg of White Portland cement, 10kg of slag powder, 15kg of regenerated fine aggregate, 6kg of iron oxide black and 2kg of iron oxide green are fully mixed and mixed, and 3kg of water is added and continued to stir evenly to obtain the mixture of the surface layer . First put the mixture of the base layer into the mold, put it on the press and press it under the pressure of 30MPa, then spread the mixture of the surface layer on the base layer, put it on the press and press it under the pressure of 30MPa, and finally natural curing for 28 God, the topping is about 11.7mm thick.

[0045] Detect the performance indicators of unfired antique green bricks: test its appearance quality, density, and compressive strength, and the results are shown in Table 1.

Abstract

The invention relates to a baking-free antique black brick and a preparation method thereof. The baking-free antique black brick comprises a basic layer and a surface layer, wherein the basic layer iscomprises clay residues, recycled aggregates and cement; the surface layer comprises white portland cement, slag powder, recycled fine aggregates, black iron oxide and green iron oxide. The clay residues are adopted to serve as one of the production raw materials of the baking-free antique black brick, the utilization rate and the additional value of the clay residues are improved, and the utilization of building waste resources is improved; moreover, the baking-free antique black brick prepared from the method can meet various performance indexes, and is suitable for masonry engineering anddecoration engineering; the production process is simple, the disposal efficiency is high, the treatment capacity is high, the field application effect is good, and the baking-free antique black brickhas good economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an unfired antique green brick and a preparation method thereof. Background technique [0002] With the continuous progress of society and the rapid development of science and technology, the construction industry is also developing vigorously. The reconstruction of old cities, the establishment of new cities, the laying of roads and bridges, and the construction of subways promote the urbanization process. Construction waste has also increased substantially. However, a large amount of residual sludge will cause many problems in the process of transportation and treatment. For example, during the transportation process, it will not only pollute the urban road surface and affect the road landscape, but also the dust in the residual sludge will enter the air with the wind and affect the urban air quality. . The more common way to deal with the residual sludge is to tra...
