preparation example Construction

[0021] The preparation method of the imitation marble brick prepared by the construction waste, the specific method steps are:

[0022] (1) The construction waste with high concrete content is processed into general quality recycled coarse aggregate and general quality recycled fine aggregate through primary crushing and secondary crushing, and then processed into high quality recycled coarse aggregate and recycled powder through particle shaping material, and then heat, mill and activate the obtained regenerated powder to obtain highly active regenerated micropowder;

[0023] (2) According to the weight parts of raw materials, it is composed of: cement: 150-210 parts, general quality recycled coarse aggregate and general quality fine aggregate: 400-800 parts, high activity recycled micropowder: 10-60 parts, water: 60-60 parts 120 parts are weighed and mixed, paved into a bottom layer, and the bottom layer is compacted by vibratory compaction, wherein general quality recycled ...

Embodiment 1

[0028] The selected bottom material has a strength grade of C20 and a thickness of 40mm. It is prepared according to the following components by weight: 150 parts of cement, 400 parts of normal quality recycled coarse aggregate and normal quality recycled fine aggregate, 10 parts of high activity recycled micropowder, and 60 parts of water. The selected surface material has a strength grade of C30 and a thickness of 8mm. It is made according to the following components by weight: 150 parts of cement, 400 parts of high-quality recycled coarse aggregate, 10 parts of high-activity recycled fine powder, and 60 parts of water. When the imitation marble brick is prepared according to the above component ratios, the flexural strength of the imitation marble brick can reach 6.5MPa.

Embodiment 2

[0030] The selected bottom material has a strength grade of C20 and a thickness of 40mm. It is prepared according to the following components by weight: 180 parts of cement, 600 parts of normal quality recycled coarse aggregate and normal quality recycled fine aggregate, 40 parts of high activity recycled fine powder, and 90 parts of water. The selected surface material has a strength grade of C30 and a thickness of 8mm. It is made according to the following components by weight: 180 parts of cement, 500 parts of high-quality recycled coarse aggregate, 300 parts of high-activity recycled fine powder, and 80 parts of water. When the imitation marble brick is prepared according to the above component ratios, the flexural strength of the imitation marble brick can reach 4.4MPa.

Abstract

The invention provides an imitation marble brick prepared by the construction waste. The brick comprises a three-layer structure, which is successively a superficial layer, a surface layer material and a bottom layer material. The superficial layer is obtained by polishing after the surface layer material is coated with a curing agent; the surface layer material comprises high-quality recycled coarse aggregate; and the bottom layer material comprises general-quality recycled coarse aggregate and general-quality recycled fine aggregate. Meanwhile, the invention provides a manufacture method ofthe imitation marble brick. The recycled material produced by the construction waste accounts for more than 80% of the total materials. The flexural strength of the prepared imitation marble brick is4-6.5 MPa, and the surface marble pattern is durable in use.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to an imitation marble brick prepared from construction waste and a preparation method thereof. Background technique [0002] The current common technical route in my country's construction waste resource industry is to process construction waste into recycled coarse aggregate, recycled fine aggregate and recycled micropowder, and then apply them to make recycled concrete, mortar, blocks and other building materials. On the other hand, my country's natural resources are scarce, and natural marble resources are becoming increasingly exhausted. At present, concrete pavement bricks made of natural stone aggregates are polished and polished to obtain imitation marble bricks. Because the recycled aggregates contain old mortar layers, the process methods are not suitable. , the quality cannot be guaranteed when making imitation marble tiles, so the invention provides a kind of imitation m...
