Building waste prefabricated part and preparation method thereof

Abstract

The invention provides a building waste prefabricated part and a preparation method thereof. The building waste prefabricated part is prepared from the following raw materials of 50 to 80% of buildingwaste, 1 to 5% of domestic garbage, 5 to 15% of cement, 5 to 9.6% of water, 0.5 to 4% of fly ash, 1 to 3% of high-efficiency water reduction agent, 0.1 to 0.5% of defoaming agent, and 0.5 to 1% of silicon ash. The building waste prefabricated part can be used for replacing the concrete prefabricated parts to provide building materials of ground tiles, cutting blocks or curbs and the like with high strength; the building waste can be treated in a harmless way at low cost, and the good economic benefit and social benefit are realized.

Description

technical field [0001] The invention relates to a construction waste prefabricated part and a manufacturing method thereof, in particular to floor bricks and blocks made of construction waste, and belongs to the field of green building material manufacturing. Background technique [0002] With the acceleration of the pace of modernization in our country, construction waste is increasing day by day. Compared with domestic waste, the reuse of construction waste in my country has not attracted much attention. Most of them are transported to the suburbs for open-air stacking or landfilling without any treatment, and stacking and landfilling require a lot of land acquisition and garbage removal. At the same time, the scattering and dust in the process of clearing, transporting and stacking have aggravated the environmental pollution. The amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated on the basis of 500-600 ton...

Problems solved by technology

However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees, garbage removal and transportation fees, and at the same time, during the process of clearing, transporting and stacking Problems such as the scattering of dust and flying dust and sand have caused serious environmental pollution.

[0003] At present, most of such a huge amount of construction waste in our country is transported to the suburbs or villages without any treatment, and is disposed of by random open-air stacking or direct landfill. Phenomenon that seriously affects the image of urban and rural areas
