Embodiment 1

[0021] A regenerated building waste brick, comprising the following raw materials in proportions by weight: 30 parts of cement, 65 parts of fine aggregate, 55 parts of coarse aggregate of regenerated brick, 1 part of polypropylene fiber, 100 parts of construction waste aggregate, and 10 parts of kaolin 1 part, 30 parts of fly ash, 1 part of water reducer, 1 part of early strength agent, 1 part of antifreeze and 15 parts of water.

[0022] Preferably, the cement is P.O42.5 ordinary Portland cement.

[0023] Preferably, the water reducer is a polycarboxylate high-efficiency water reducer.

[0024] Another technical problem to be solved by the present invention is to provide a kind of preparation method of construction waste recycled brick, comprising the following steps:

[0025] 1) Prepare cement, fine aggregate, recycled brick coarse aggregate, polypropylene fiber, kaolin, fly ash, water reducer, early strength agent, antifreeze and water, pre-wet the mixer cylinder, and then...

Embodiment 2

[0031] A regenerated brick from construction waste, comprising the following raw materials in proportions by weight: 37.5 parts of cement, 72.5 parts of fine aggregate, 62.5 parts of coarse aggregate of regenerated brick, 3 parts of polypropylene fiber, 15 parts of kaolin, and 40 parts of fly ash , 3 parts of water reducer, 3 parts of early strength agent, 3 parts of antifreeze and 20 parts of water.

Embodiment 3

[0033] A regenerated building waste brick, comprising the following raw materials in proportion by weight: 45 parts of cement, 80 parts of fine aggregate, 70 parts of coarse aggregate of regenerated brick, 5 parts of polypropylene fiber, 100 parts of construction waste aggregate, and 20 parts of kaolin 5 parts, 50 parts of fly ash, 5 parts of superplasticizer, 5 parts of early strength agent, 5 parts of antifreeze and 25 parts of water.

[0034] The beneficial effects of the present invention are: the rational utilization of resources solves the problems of waste of resources and environmental pollution caused by landfilling and stacking of construction waste, provides strong technical support for the effective utilization of construction waste, and improves the efficiency of recycled brick-and-bone construction. The mechanical properties and working properties of permeable concrete after molding are good, the compressive strength, flexural strength and splitting strength chang...

Abstract

The invention relates to the technical field of regenerated bricks, and discloses a construction waste regenerated brick which comprises the following raw materials in parts by weight: 30-45 parts of cement, 65-80 parts of fine aggregate, 55-70 parts of recycled brick coarse aggregate, 1-5 parts of polypropylene fibers, 10-20 parts of kaolin, 30-50 parts of fly ash, 1-5 parts of a water reducing agent, 1-5 parts of an early strength agent, 1-5 parts of an anti-freezing agent and 15-25 parts of water. The invention further relates to a preparation method of the construction waste regenerated brick, which comprises the steps of 1) preparing cement, fine aggregate, regenerated brick coarse aggregate, polypropylene fibers, kaolin, fly ash, a water reducing agent, an early strength agent, an anti-freezing agent and water, pre-wetting a barrel of a stirrer, then putting the regenerated brick coarse aggregate, the cement and the fine aggregate into the stirrer, pre-stirring for 2-3 minutes, uniformly stirring to obtain a mixture for later use, uniformly dispersing the polypropylene fibers into the obtained mixture, and carrying out dry mixing for 1-2 minutes to obtain mixed powder. According to the construction waste regenerated brick and the preparation method thereof, the purpose of higher strength is achieved.

Description

technical field [0001] The invention relates to the technical field of recycled bricks, in particular to a recycled brick from construction waste and a preparation method thereof. Background technique [0002] Regenerated bricks are made of broken ruins as aggregates, mixed with cut wheat straw as fibers, cement, sand, etc., and made into lightweight blocks by the original brick factory in the disaster area, and are used as reconstruction materials for the disaster area. The material "regeneration" of waste materials is also the spiritual and emotional "regeneration" of post-disaster reconstruction. [0003] The existing construction waste recycled bricks have low cost and good environmental protection effect, but in the actual use process, the strength of the existing construction waste recycled bricks is not high enough, and although the preparation method is simple, the quality of the recycled bricks cannot be better guaranteed, so A construction waste regenerated brick ...
