Embodiment 1

[0030] Weigh 4.56kg of construction dregs, 1.6kg of cement, 0.96kg of gypsum, 0.48kg of superfine stone powder, 0.4kg of mineral powder, 2200g of water demand, and 11.4L of polystyrene particles, and place them in a stirrer at room temperature (25°C) Stir for 3 minutes to obtain the mixture, and then vibrate and form it to make a lightweight block of 100mmⅹ100mmⅹ100mm to obtain the experimental component F1. The curing system is standard curing. The effects achieved by curing for 7 days and 28 days are shown in Table 1.

Embodiment 2

[0032] Weigh 4.56kg of construction dregs, 2.0kg of cement, 0.48kg of gypsum, 0.48kg of superfine stone powder, 0.4kg of mineral powder, 2200g of water demand, and 11.4L of polystyrene particles, and place them in a stirrer at room temperature (25°C) Stir for 3 minutes to obtain the mixture, and then vibrate and form it into a lightweight block of 100mmⅹ100mmⅹ100mm to obtain the experimental component F2. The curing system is standard curing.

Embodiment 3

[0034] Weigh 4.56kg of construction dregs, 1.6kg of cement, 0.48kg of gypsum, 0.48kg of superfine stone powder, 0.88kg of mineral powder, 2200g of water required, and 11.4L of polystyrene particles, and place them in a stirrer at room temperature (25°C) Stir for 3 minutes to obtain the mixture, and then vibrate and form it to make a lightweight block of 100mmⅹ100mmⅹ100mm to obtain the experimental component F3. The curing system is standard curing. The effects achieved by curing for 7 days and 28 days are shown in Table 1.

Abstract

The invention relates to a civil construction material, in particular to a construction muck lightweight building block, which is characterized in that the construction muck lightweight building blockis prepared from the following components in parts by weight on a dry basis: 50 to 80 parts of construction muck, 15 to 25 parts of cement, 10 to 20 parts of mineral powder, 10 to 20 parts of gypsumand 10 to 20 parts of ultrafine stone powder; and the volume of the polyphenyl granules is calculated according to the setting of the dry density of the lightweight building block, and the dry densitycan be 600kg / m<3>-1200kg / m<3>. According to the building muck lightweight building block, the building block for construction is prepared by taking construction muck and waste recycled materials as raw materials, so that the construction waste soil can be recycled, secondary treatment is avoided, and the main purposes of reducing the cost, saving resources and protecting the environment are achieved; and the construction waste soil accumulated around a construction site can be effectively consumed, the cost is saved, and a new way for treating the waste soil is provided.

Description

technical field [0001] The invention relates to a civil construction material, and relates to a preparation method of the civil construction material. Background technique [0002] At present, the amount of construction waste produced in our country is more than billions of cubic meters each year, and a considerable amount of construction waste is piled up and dumped around the urban ring road and the urban-rural junction every year, which has a great impact on the city appearance, environmental sanitation and ecological environment. big negative impact. [0003] The construction of the construction dregs disposal site can only temporarily store dregs, and if the dregs cannot be effectively utilized, the amount of dregs accumulated will become larger and larger. The muck disposal field requires personnel management and occupies a large amount of land. If it is not properly disposed of, it will cause great environmental and economic problems. Therefore, it is necessary to c...
