Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to specific embodiments.
Example one
A method for manufacturing a pavement brick by utilizing construction waste comprises the following steps:
A. mixing the crushed construction waste, asphalt pavement waste and wood waste to serve as aggregate, and adding fluorite ore to serve as a reinforcing agent;
B. adding water into the raw materials, stirring by using a stirrer, aging for 72 hours, and then extruding and molding by using a vacuum brick machine;
C. cutting the formed semi-finished product by an automatic blank cutting machine, and finally sintering at the high temperature of 850-.
The mass proportions of the construction waste, the asphalt pavement waste, the wood waste and the fluorite ore are respectively 55-57%, 17%, 25% and 1-3%.
The fineness of the construction waste and the asphalt pavement waste is below 2mm, and the fineness of the wood waste is 0.5-1 mm.
The construction waste can be replaced by waste incineration ash with the same mass ratio.
The asphalt pavement waste can be replaced by fly ash with the same mass ratio.
The invention takes the construction waste, the asphalt pavement waste and the wood waste (waste wood furniture, sawdust and the like) which are crushed and sieved as aggregate, adds fluorite ore as reinforcing agent in a certain proportion, mixes the raw materials, adds proper amount of water, stirs the mixture by a stirrer, ages the mixture for 72 hours, extrudes and forms the mixture by a vacuum brick machine, uses an automatic blank cutter to cut the mixture into required shape and size, and finally carries out high-temperature sintering at 850 ℃ and 900 ℃. Compared with the processing of common pavement bricks, the pavement brick provided by the embodiment meets the requirements of pressure resistance and water seepage resistance, and reduces the production cost. The raw materials of the formula are derived from building and industrial wastes, so that the treatment problem of building waste and industrial slag discharge is solved, the problem of environmental pollution caused by the building waste can be relieved, the land occupation caused by landfill is reduced, and the cyclic utilization of the building waste is realized.
The fineness and the mixing amount of the construction waste, the asphalt pavement waste and the wood waste are strictly controlled, otherwise quality problems such as cracks, water seepage and the like of products can be caused. The crushing fineness of the construction waste and the asphalt pavement waste is required to be below 2mm, and the fineness of the wood waste is 0.5-1 mm.
Compared with the prior art, the invention greatly utilizes the construction and industrial wastes, obviously reduces the production cost, and effectively solves a series of problems of forming, drying, product water seepage and the like in the prior art. The technology can be used for producing high-quality and low-cost footpath bricks, and can also be used for producing curbstones, tree pool cover plates and the like.
In the embodiment, 17% of waste asphalt is blended, so that the plasticity of the pavement brick product is properly improved, and the thermal performance, the compressive strength and the water seepage resistance of the product are improved. In the embodiment, 25% of the wood garbage is mixed, and the wood garbage has certain heat, so that the product roasting requirement can be met only by mixing a small amount of raw coal during high-temperature roasting in the later period, thereby being beneficial to saving energy, reducing the production cost and reducing the air pollution. The fluorite mineral powder is added in the formula by 1-3 percent, mainly aiming at reducing the roasting temperature of the product (the compressive strength of the product cannot be reduced when the roasting temperature is reduced by 50-80 ℃), ensuring the strength of the product, and reducing the energy consumption and the environmental pollution caused by burning coal by reducing the roasting temperature.
Example two
The difference between the embodiment and the first embodiment is that the construction waste can be replaced by the waste incineration ash with the same mass ratio. This embodiment can retrieve the waste incineration lime-ash and recycle, has further improved the recovery rate of recycling of discarded object.
